DIETARY IN HEALTH AND DISEASE. CHAPTER I. FOOD AND ITS RELATIONS TO THE HUMAN BODY. A knowledge of dietetics is protective. Dietetics deals with the derivation of the greatest nutritive values from a proper combination of foods at a minimum amount of effort upon the part of the body. Nutritive values are liable to damage in the preparation of food. Food supply to the human body is primarily a selective problem. The processes by which the body makes use of the food may become so prejudiced by dietetic error that certain serious disturbances result. Dietetics is the science of feeding. It involves a study of the functions of food, its composition, selection, preparation and service. It should extend to the study of the processes by which foods are utilized in the human body. Function of Food.—Foods are materials which when taken into the body: 1. Yield energy to the tissue cells. 2. Build and repair tissues. 3. Regulate the body processes. The energy of the tissue cells is derived from the food- stuffs. It is converted in these cells in the process of their growth and repair. Functional activity involves the break- ing down of tissue material and the consequent liberation of 18 FOOD AND ITS RELATIONS TO THE HUMAN BODY energy. Catalytic and oxidative processes are involved in these transformations. Oxidation of waste materials may be compared to the combustion of fuel. An end-result is the maintenance of body temperature, regulated not only by the production of heat as the result of tissue change, but also through the agencies of heat loss by radiation, conduction and evaporation from the body surfaces by aid of the circu- lation, the respiration, secretion and excretion. Certain food materials are susceptible of storage in the tissues, and these stores may be mobilized in underfeeding, fasting, starvation or disease. Losses of weight result. The functional processes involved in the utilization of food, the conversion of energy, the development and break- ing down of tissue cells are termed metabolism. Metabolism has two phases: (a) Anabolism, or the building up of tissue complexes. (b) Ivatabolism, or the breaking-down of tissue materials. Classification of Food.—Foods may be classified in two principal groups: Inorganic Foods.—Water, oxygen, mineral matter. Organic Foods.— Proteins, fats, carbohydrates. Composition of Food.—Fifteen chemical elements are found in the human body. A table of these chemical elements, for a person weighing 148 pounds, is as follows: Pounds. Oxygen 92.4 Carbon 31.6 Hydrogen . . .14.6 Nitrogen 4.6 Phosphorus . . 1.4 Calcium 2.8 Sulphur 0.24 Iodine ..... a trace Pounds. Chlorine 0.12 Sodium 0.12 Iron 0.02 Potassium .0.34 Magnesium . . 0.04 Fluorine 0.02 Silica a trace The first four are the most important, as they are necessary in the building of muscular and fatty tissue. Certain others COMPOSITION OF FOOD 19 are chiefly used in the structural framework of the body, as the bones, teeth and cartilage. These elements form food compounds which are classified as follows: Proteins. —This is the most important food group. It is composed of carbon, hydrogen, oxygen, nitrogen and sulphur. The animal kingdom supplies the proteins, w7ith a few excep- tions. The typical protein foods are milk, eggs, meat, cheese, fish, legumes and cereals. The legumes are vegetable pro- teins and consist of peas, beans and lentils. Cereals which are high in protein content are oatmeal, rice and cornmeal. Carbohydrates.—These foods contain carbon, hydrogen and oxygen. They are divided into three groups: starches, dextrins and sugars. The carbohydrates are energy con- tributors. They are derived almost entirely from the vege- table kingdom. Fats.—The fats contain carbon, hydrogen and oxygen. The oxygen is present only in small amounts. These foods are also called the “hydrocarbons.” Fats are obtained from both animal and vegetable foods, and are also energy pro- ducers. The principal fats are olein, palmitin and stearin. Mineral Matter.—Minerals are found in varying quanti- ties in foods. The salts of the tissues and body fluids are: sodium and potassium chlorides, sulphates, phosphates and carbonates; calcium and magnesium phosphates and carbo- nates. The calcium and magnesium enter into the structure of the framework tissues of the body. The salts are found in greatest quantity in the green vegetables, cereals, milk and the red meats. Water.—Water is found not only in free form, but in food- stuffs. It consists of hydrogen and oxygen in the propor- tions of 2 to 1. It is not only a tissue food, but a diluent, a solvent, an agent of transfusion, circulation, suspension, heat regulation and waste elimination. 20 FOOD AND ITS RELATIONS TO THE HUMAN BODY Vitamins.—Vitamins constitute the sixth group necessary to health and development. They contribute by unknown means to tissue growth and repair. They are variably sus- ceptible to the influences of heat and storage. They are most definitely secured in fresh uncooked foods. The vita- mins are divided into three known classes: Vitamin Content of Food from Experiments of Dr. J. F. McClendon. Fat soluble A. Water solu- Water solu- Found in (a) Growth. (b) Anti- ophthalmic.

Milk approaches to an ideal food, as it contains the five food principles in a most digestible form and supplies vitamins. It has, however, a high-water content, which renders it too dilute a food for adult use. It lacks mass, a necessary feature for the promotion of motility. It is essential that a certain moderate amount of protein food be taken. The nitrogen taken into the body and the nitrogen excreted should balance. When the intake exceeds the output, it usually means that nitrogenous tissue is being built. The reverse indicates the breaking down of nitrog- enous tissue. A normal appetite is something of a guide to food selection. Cereals, lacking in fat, suggest the addition of cream, milk and butter; meats, lacking in carbohydrates, suggest the association with them of bread or potatoes. Preparation of Food.—The preparation of food is a vital matter. Food values may be improved or impaired by application of heat. The carbohydrates are rendered more digestible by cooking; the proteins are coagulated and their food values diminished upon the application of too high or prolonged heat. The fats are impaired by intense heat, a chemical change taking place which produces substances irritating to the gastro-intestinal tract. The Service of Food.—This suggests a study of the esthetic side of the food problem. Experiments show that food values are enhanced or impaired by their influence upon the special senses. Food by its appeal to the sight, smell and taste of the patient stimulates the flow of the digestive juices, and thus it is readily utilized. Distribution of Food in the Body.—Food is distributed in the body by the blood and lymph. The blood consists of red and white corpuscles and plasma. The red corpuscles carry oxygen from the lungs; the white corpuscles are food 22 FOOD AND ITS RELATIONS TO THE HUMAN BODY carriers and defense agencies against.microorganisms. The plasma of blood and lymph contains water, salts, dextrose, soluble proteins, emulsified fats, etc., all of nutritive value. It carries, also, carbon oxide and both nitrogenous and non- nitrogenous forms of waste material for elimination through the organs of excretion. A considerable mass of the debris of food, by way of undigested or indigestible material, together with large numbers of bacteria which tend to the destruction of this debris, remains to be removed from the lower bowel. Adjuvants of Food.—To human food, substances of indiffer- ent nutritive value are commonly added as variants of flavor and promoters of appetite and digestion. These include spices and other condiments and certain stimulating bever- ages such as tea, coffee, etc. BIBLIOGRAPHY. McCollum: The Newer Knowledge of Nutrition (Macmillan).

The processes by which the body makes use of food are digestion, absorption, assimilation, metabolism and elimina- tion. Digestion.—The sum of the changes which food undergoes to put it into such a form that it can be absorbed and dis- tributed is called digestion. By cooking and other means of preparation a certain measure of this work may be accom- plished, and this external digestion made to save the labor of the digestive tract. In digestion the following changes take place: 1. Solid or semisolid foods are reduced to soluble form. 2. Carbohydrates are broken down into single sugars; some indigestible material remains which is valuable in the dietary. It may be called roughage. It is helpful to the digestion in that it stimulates the intestinal lining by direct contact and provokes vigorous muscular reactions by mass. It carries along with it other forms of debris which have not the necessary bulk to provoke peristalsis. 3. Proteins are reduced to proteoses, peptones and finally to polypeptids and amino-acids. 4. Fats break down into glycerol and fatty acids. 5. Salts only require solution and dilution, to which water contributes, as it does to the solution and transfusion of other products of digestion. Aids to Digestion. — I )igestion may be aided in a number of ways: 24 USE OF FOOD 1. Food should be thoroughly masticated, thus assisting dilution and solution and increasing its surface of exposure to and permeation by the digestive juices. 2. Concentrated foods such as candy, cheese or nuts should be taken in combination with other foods which serve to dilute them. 3. Food should not be eaten when one is fatigued or suffering from severe nervous strain. 4. Digestion is influenced by the amount of food taken at a time; quantity proportioned to the capacity of the stomach promotes ready digestion. 5. Well-balanced meals are more easily digested than those in which single foods are served in excess. 6. Food well cooked and artistically served promotes the flow of “appetite juices,” and so favors digestion. 7. In extreme cases of faulty digestion, food may be pre- digested; peptonized milk, twice-baked bread and emulsified fats are illustrations of methods. Physical and Chemical Features of Digestion.—Digestive changes take place, in the alimentary canal, as the result of the mechanical disintegration of food by the teeth and by the muscular movements of the stomach and intestinal walls and by its dilution with the water of the digestive fluids. By these measures the easier penetration of the food by the digestive juices is secured. The chief factors in the chemical digestion of food are the ferments or enzymes which are present in the digestive juices. These juices are secreted by the salivary and gastric glands, the pancreas, the liver and the intestinal glands. The enzymes are associated with proteins and are them- selves digested in turn by the action of successive ferments. Each ferment acts only upon one class of substance. ASSIMILATION 25 Place of action. Place of origin. Secretion. Enzymes. Function. Chemical reaction. Mouth Salivary glands Saliva Ptyalin Converts starch into maltose Alkaline. Stomach Gastric follicles Gastric juice Pepsin Rennin Converts proteins into proteoses and peptones Coagulates casein of milk Acid. Small intestine Pancreas Pancreatic juice Amylopsin Trypsin Lipase Converts starch into maltose Splits proteoses into peptones, polypep* tids and amino- acids Splits fats into fatty acids and glycerin Alkaline. Small Intestinal Intestinal Maltase Changes double su- intestine glands juice Lactase Sucrase Erepsin gars to dextrose, levulose, galactose, etc. Splits peptones into amino-acids Small intestine Liver Bile None Emulsifies and pro- motes absorption of fats Alkaline. Bile.—The bile in addition to emulsifying and promoting the absorption of fats, stimulates peristalsis, limits bacterial growth, and neutralizes the acid output of the stomach. Absorption.—No absorption takes place in the mouth and ordinarily none in the stomach. This process takes place in the small intestine and to certain extent in the large bowel. The surface of the small intestine is furnished with tiny projections called villi. These villi contain capillary blood- vessels and lymph radicals, through the thin walls of which digested foods are absorbed into the blood and lymph stream, and are thus distributed to the tissue cells. The leukocytes, or white cells of the blood and tymph, assist in taking up food materials, and especially fats. Assimilation.—This is the process by which the tissue cells select or appropriate food materials. It is a function of all living cells. 26 USE OF FOOD Metabolism.—This is the function by which food material, so assimilated, is converted into tissue material and by which the latter is ultimately changed into waste material. Elimination.—The kidneys, the skin and the air passages are organs of elimination. The large intestine absorbs water and salts and evacuates the remaining debris of digestion. It is not, properly speaking, an organ of excretion. BIBLIOGRAPHY. Pettibone: Physiological Chemistry (Mosby). Carter, Howe and Mason: Nutrition and Clinical Dietetics (Lea & Febiger). Friedenwald and Ruhr: Diet in Health and Disease (Saunders). CHAPTER III. WATER. Sources of Water.—The composition of water is two parts of hydrogen to one part of oxygen. Its sources are lakes, rivers, springs, wells or rainfall. Water is pure in its first molecular state hut collects impurities readily as a result of its highly solvent power. Water which comes from a great height or a great depth is considered the most certainly pure. As water dissolves solids, liquids and gases, therein lies its danger of contamination, and especially if the water travels far from its source. The rain-water collected at the close of a storm is pure but tasteless, owing to the lack of mineral matter and oxygen. Water coming from surface sources may carry with it the products of decomposition of organic matter, impurities resulting from sewage or animal excreta, physical impurities of various sorts and a greater or less percentage of minerals. Classification. —1. Soft ivater is a relative term: it is water containing a small, but variably small, amount of mineral matter. Water regarded as soft in one part of the country may be regarded as hard in another. 2. Hard water is water containing calcium or magnesium salts to excess. It is not good for drinking purposes unless boiled. These salts can usually be precipitated sufficiently by boiling to make it possible to use a hard water for drinking purposes. Hard water is unpleasant to the skin if used for bathing purposes. Bladder and kidney-stone cases are said to be more prevalent in localities where hard water is habitu- ally used for drinking. 28 WATER 3. Mineral water is water coming from the soil rich in minerals, and carries with it salts of iron, magnesium, sodium, potassium, lithium, etc. Mineral waters are not advised as beverages for constant use, but are sometimes used in large quantity for medicinal purposes over periods of time. Occurrence of Water in the Body.—Two-thirds of the body weight is water. Water exists in combination with other materials in the body, and as free water it is eliminated. Under ordinary conditions the body maintains a certain water equilibrium, and the quantity of water taken into the body determines more or less closely the quantity eliminated by the skin, the air passages, kidneys and large intestine. The quantity contained in the body fluids and held in the tissue cells may be temporarily increased in considerable measure. Water retention is one of the factors in the devel- opment of edema or dropsy. Uses in the Body. —1. Water enters into the composition of all the tissues and fluids of the body. 2. It dilutes the blood and the lymph, serving as an agent of the circulation. 3. It is a vehicle for the elimination of waste material from the body. 4. It acts, through its evaporation from the body surfaces, as a regulator of body temperature. 5. It aids digestion by the dilution of foods and of the digestive fluids. 6. It aids in absorption and assimilation as an agent of transfusion. Quantity Required by the Body.—If there is a deficiency of water the body suffers. Six to eight pints of water a day is needed; almost half of this can be counted upon as being taken in with the food, as foods that are to all appearances solid contain 20 per cent or more of water and many contain METHODS OF PURIFICATION 29 as high as 90 per cent. Water should be taken freely between meals, early in the morning and at night. Moderate quan- tities may be ingested with meals without prejudice to digestion. Dietetic Uses. — 1. Hot water is advised in the treatment of indigestion; it increases the dilatation of arterioles in the stomach and intestines. 2. Cold water is stimulating to the digestive organs of people who are in good health and serves to promote elimi- nation. 3. Lukewarm water (90° F.) acts as an emetic when taken in large quantities. 4. Whenever fluid has been actively withdrawn from the tissues by hemorrhage or diarrhea, water is immediately and freely given to compensate the loss. 5. In fever, water supply is urged to meet the greater loss it evolves. 6. In event of the retention of nitrogenous waste material, water is often given with the idea of promoting a free flush of the tissue cells. 7. In certain disorders such as cardiac cases with edema, or in nephritis with edema, water is restricted. It is also restricted by some physicians in hypertension on account of its increase of the volume of the blood. 8. If constipation is due to too great an absorption of fluid from the contents of the large intestine, certain sub- stances such as agar-agar, vegetable fiber foods, etc., are given as convenient water retainers. Methods of Purification.—Distillation is one of the surest methods. Distilled water should be aerated to render it palatable. It is used in compounding medicines, in times of epidemic and on board ship. 30 WATER Filtration.—Tliis method is only reliable when competent and clean filtering materials are used. However, the history of epidemics shows that localities in which filtered water is used will be free from water-borne diseases while those using unfiltered water will not. A filter must be kept in perfect condition, whether it is of the small domestic type attached to the faucet in the home or the large sand-beds used in filtering a city water supply. Chemical Action.—This is the least desirable method. It is harmless, but frequently alters the taste of the water. Chemicals are used as coagulants of the physical and bac- terial impurities and as sterilizers of water. Heat Sterilization.—This is a reliable method. While boiled water tastes flat, it can be aerated by pouring it from a height. Boiling also tends to eliminate an excess of lime. For ordinary purposes, distilled water, soft water or boiled water are not recommended except in times of epidemic danger. The few grains of lime salts to the gallon that ordinary drinking water contains are not objectionable. Rosenau: Preventive Medicine and Hygiene (Appleton). Hutchinson: Food and Dietetics (Wm.

Minerals or salts are contained in the ordinary mixed diet in sufficient quantity to maintain nutri- tion, with the exception of sodium chloride. The mineral supply comes from both vegetable and animal foods. Some- where in the growth of the plant the inorganic salts are built into its structure and often changed into organic salts that can be utilized. Sodium chloride is obtained from the evaporation of sea water or from mines. 2. Vegetables and cereals are rich in phosphorus, iron and calcium. 3. Animal foods are rich in phosphorus, iron and sulphur. 4. Fruits and vegetables contain vegetable salts, as citrates, malates, tartrates and benzoates. These organic salts are readily decomposed, their acids are oxidized, while their bases combine with carbon dioxide to form carbonates and so serve to increase the alkalinity of the body fluids. 5. Water is another source of mineral matter. Mineral waters are classified according to the inorganic salts they contain, as lithia waters, iron waters, sulphur waters, etc. The lithia waters are supposed to be valuable in gout and in certain disorders of the kidneys, and iron and sulphur waters to improve conditions of the blood and the skin. These, however, are therapeutic rather than dietetic measures. Occurrence in the Body.—From 4 to 5 per cent of the body weight is of mineral matter. It is found in all tissues and fluids, but especially in the bones, teeth and cartilage. It is found in the various compounds of sodium, potassium, phosphorus, calcium, sulphur, magnesium, chlorine and iron. The minerals only require dilution and solution for their 32 MINERAL MATTER digestion and absorption. They are eliminated mainly through the kidneys. Uses in the Body. —1. Relation of Inorganic Salts to Physio- logical Processes. —(a) Rigidity and growth of the skeleton. The inorganic salts have a definite relation to normal body structures and to normal physiological processes. The rigidity of the skeleton, the hardness of the teeth and the resistance of cartilage, for example, depend on the deposi- tion of salts, chiefly calcium phosphate and calcium car- bonate. Growth of the above structures during childhood and their repair in later life are accomplished by laying down inorganic salts in a framework of living cells. (b) Digestion.—In digestion the salts play their role in various ways. The hydrochloric acid essential to gastric digestion is thought to be derived from the sodium chloride intake. Clotting of milk in the stomach depends on the presence of calcium, without which no coagulation occurs. (c) Metabolism.— The metabolic exchange which occurs between the living cells and the body fluids, and the passage of these fluids through the vessel walls into the tissue spaces and back again, are accomplished by means of osmosis, which is governed by the salt concentration of the fluids involved. The osmotic pressure of the cells and body fluids, which is so important in cell nutrition, must be regulated by the salt content. The cells of the body are constantly bathed in plasma which escapes from the vessels to a very large extent as a result of differences in osmotic pressure. A nicety of balance between the osmotic pressure of the blood and of the intercellular fluid is required for the normal functions of the tissues bathed by this fluid. Any disturbance in this balance results in a pathological condition. Although the causes of edema are very imperfectly understood, still it is believed that an accumulation of salts in the tissues accounts for the drawing out of fluid from the bloodvessels into the tissue spaces. USES IN THE BODY 33 (d) Activation of Enzymes.—The activation of digestive enzymes such as trypsin may depend upon the salts in the intestinal tract. (e) Irritability of Muscles and Nerves.— The irritability of muscle and nerve tissues has been shown to depend in part upon the calcium, sodium and potassium present. (/) Blood.—Iron in the hemoglobin molecule, although small in amount, is essential to the important oxygen- carrying function of the blood. 2. Relation to Protective Physiological Mechanisms. — (a) Normal Alkalinity of Blood.—The normal alkalinity of the blood is maintained by an excess of sodium bicarbonate, which affords what is called the “buffer value” of the blood. The acid products of metabolism are rendered neutral with- out changing the alkalinity of the blood and the tissue juices, the sodium bicarbonate constituting a “buffer” or factor of safety against a dangerous tendency toward acidosis. In a series of experiments on dogs, fatal results were produced by absolute salt starvation. Upon the decomposition of protein in the body the sulphur which it contains forms sul- phuric acid, which under a normal diet would have united with the basic salts of the foods. These basic salts being absent, the acid unites with the basic elements of the living cells, producing acidosis and serious nutritional derange- ment. (b) Clotting of Blood.—The salts are made use of in certain normal protective body mechanisms such as the clotting of blood, which depends on the presence of calcium. 3. Relation to Protective Mechanisms in Pathological Processes. — (a) Repair of Fractured Bones.—In the repair of destructive or pathological processes the salts are often used. The parts of a fractured bone are reunited by laying down new bone with its salt content to bridge the separated parts. 34 MINERAL MATTER (b) Calcification in Tuberculosis.—In tuberculosis of the lungs, diseased areas often heal and finally become obliter- ated by the deposit of calcium salts. 4. Relation to Deficiency Diseases. —When for any reason the salt content of the diet is inadequate, or when the body loses the power to synthesize the salts present in the food, well-defined pathological conditions result. In rickets the mechanism of laying down calcium phosphate in the bones is at fault and results in the soft bones of the rachitic child with his soft, box-shaped head and bowed legs. Acid- and Base-forming Elements in the Dietary.—The question of acid-forming and base-forming elements in the diet is an important one. In the course of metabolic trans- formation the chlorine, sulphur and phosphorus of the food- stuffs yield acids, whereas the sodium potassium, calcium and magnesium yield bases. The normal dietary should be one which should yield at least sufficient base-forming ele- ments to neutralize the acids formed. If these acids are not neutralized by the bases of the diet they must be neutralized by the fixed bases of the tissues. We then have a serious pathological condition which embraces one of the most harmful features of acidoses. Meat and eggs are rather pronounced acid-forming foods, whereas the grain prod- ucts are acid-forming to a less degree. Milk is a base- forming food while vegetables and fruits are base-formers to a marked degree. The reason the fruits, which may be initially acid, yield an excess of bases on oxidation is the fact that their acidity is caused by organic acids, present for the most part as acid potassium and sodium salts, and these salts, readily dissociated by carbon dioxide, yield potassium carbonate and bicarbonate. Dietetic Uses of Salts.—Aside from the constant need of minerals, there are conditions under which the body needs a larger supply. DIETETIC USES OF SALTS 35 1. Growing children need the calcium salts for bone- building and the phosphorus and the iron salts to maintain rapid tissue-building in general. Eggs, cereals, milk and vegetables are indicated. 2. Convalescents or anemic patients require iron and phosphorus. 3. During pregnancy and lactation, larger supplies of calcium and phosphorus are necessary, or the calcium for the development of the child may be drawn from the mother’s structure. 4. In edema sodium chloride is withheld from the diet. The body maintains a certain concentration of this salt, therefore if the intake of sodium chloride is reduced, elimina- tion of water from the body results. Foods rich in iron. Per cent.

In the animal foodstuffs they are found in any quantity only in the liver and muscles in the form of glycogen, while very minute quantities of dextrose are in solution in the blood and of lactose in milk. Definition.—The carbohydrates are compounds of carbon, hydrogen and oxygen. The C is in the form of C6 or some multiple of 6 and the H and O are always in the proportion to form water. The four typical groups in this class of physio- logical or dietetic interest are starches, dextrins, sugars, vegetable gums and woody fibers. Classification.—A classification of the carbohydrates based upon their chemical composition, but in physiological order, is as follows: (a) Polysaccharids or starch group, C6Hio05. 1. Starch. 2. Cellulose. 3. Dextrins. (b) Disaccharids or double sugar group, Ci2H220n. 1. Sucrose. 2. Lactose. 3. Maltose. (c) Monosaccharids or single sugar group, C6IIi206. 1. Dextrose. 2. Levulose. 3. Galactose. 38 CARBOHYDRATES Detailed Study of Each Group. —1. Starch, sugar and woody fiber are found together in plants. Starch is the reserve or stored food material of plant life. It is found in the store- houses of plants as the roots, seeds and underground stems. It is partly changed to dextrin or to maltose by the action of diastase as the seed ripens and the plant grows. The starch granule is covered with a delicate envelope of cellu- lose. Hot water and long cooking break down this covering, which otherwise makes the starch impossible of digestion. Cellulose is of value to the diet, as it contributes bulk to the food, encouraging muscular activity in the intestines. It constitutes the structural framework of plant cells and is abundant throughout the vegetable kingdom. 2. Dextrins are formed in the hydrolysis of starch to dex- trose. They are readily soluble in water. Glycogen is a form of dextrin and serves as a reserve food supply, stored in the liver and other tissues of animals. It is readily converted into dextrose. 3. Gums are amorphous carbohydrates which exist in the juices of nearly all plants. They have the property of taking up water and forming a thick, sticky mass. 4. Maltose is a vegetable and digestive product obtained by treating gelatinized starch with a ferment. In the body the ferments are ptyalin and amylopsin; in plants, diastase. Diastase is a substance formed from the albumin of seeds during germination. Maltose is much sweeter than glucose. In its physiological form it is the least liable to fermentation of the double sugars. It is easily split into two molecules of dextrose. 5. Lactose, or milk sugar, is found in the milk of all mam- mals. It is obtained in commercial form by evaporating clear, fresh whey from which all fat and albumin have been removed. It is less sweet and soluble than cane sugar; it CLASSIFICATION OF VEGETABLE FOODS 39 feels gritty in the mouth and does not ferment so easily as cane sugar. 6. Sucrose (cane sugar, beet sugar) is one of the most important and popular forms of food. It is obtained from both the sugar cane and the sugar beet. It is absorbed in the form of dextrose and levulose. In strong solutions it irritates the alimentary canal and is apt to undergo fermen- tation. According to Hutchinson, 4 ounces of sugar can be taken by a healthy individual per day. More is rapidly excreted by the kidneys, giving rise to glycosuria. However, the “carbohydrate limit,” or capacity for handling carbo- hydrate food, varies with the individual. 7. Dextrose, glucose and grape sugar are found in: (a) Grapes, dates and figs. (b) In smaller quantity in nearly all fruits and honey. (c) In the blood, lymph and tissues of all animals in very small amounts. 8. Levulose (fructose or fruit sugar) is similar to dextrose, except that it turns the ray of polarized light to the left. It is a sugar found in fruits and honey and is very expensive and hard to crystallize. 9. Galactose is a result of chemical reaction. It is obtained by splitting one of the members of .the disaccharid group, lactose, by the agency of certain acids or ferments. Galac- tose does not ferment easily. Classification of Vegetable Foods. —1. Cereals are the most valuable of vegetable foods. They are ground or pounded into flour or meal. Those commonly used are: wheat, rye, maize, barley, rice, millet, oats and buckwheat. 2. Legumes are sometimes called the “meat of the vege- table kingdom,” as they contain a liberal amount of protein. Peas, beans and lentils are the best known of the legumes. Although they contain much protein, they are perhaps less 40 CARBOHYDRATES easily digested than meat, a point upon which authorities differ. 3. Routs, tubers and bulbs may be grouped together. These are valuable table vegetables on account of their high starch content, but because of their high-water and low-protein content are inferior to either the cereals or to the legumes. Examples of these foods are: Roots: beets, radishes, carrots, turnips, parsnips. Tubers: potatoes, Jerusalem artichokes. Bulbs: onions, leeks, chives, garlic, shallots. 4. Green vegetables are valuable, not because of their nutrients, but because of their variety and the bulk they lend to the dietary. They contain valuable salts. Those containing sulphur (cabbage) should be avoided by those of weak digestion. Examples of green vegetables are: lettuce, cabbage, spinach, celery, cauliflower and cress. 5. Fruits. (a) Orchard fruits. 1. Pome fruits. Apple (crab apple), pear, quince. 2. Drupe fruits. Apricot, cherry, date, nectarine, peach, plum, persimmon. 3. Citrus fruits. Citron, grapefruit, kumquat, lemon, lime, mandarin, orange and tan- garin. (b) Vine fruits. 1. Grapes. (c) Small fruits. 1. Blackberry, black-cap, blueberry, barberry, cranberry, currant (red and white), currant (black), dewberry, elderberry, gooseberry, huckleberry (whortleberry, bilberry), logan- berry, mulberry, raspberry, service berry (red and white), squawberry, strawberry. DIGESTION 41 To this list may be added: (d) Miscellaneous fruits: 1. Agave (alligator pear), banana, bread-fruit, fig guava, mango, olive, papaw, pomegranate, pineapple. (e) Garden fruits: 1. Citron, cucumber, egg-plant, vegetable marrow, melon, cantaloupe, muskmelon, watermelon, pumpkin, squash, tomato. 6. Nuts are high in fat, carbohydrate and protein values. They are a very concentrated form of food, and if carefully prepared are not difficult of digestion. Nuts are usually eaten raw and should be thoroughly masticated or ground. Chestnuts contain much starch and are more digestible if cooked. 7. Fungi. Two varieties eaten are: 1. Mushrooms, which have little food value and are not readily digested. 2. Truffles, which are an underground fungus. They are valuable as flavoring agents, and are grown in France, Italy and England. There are several varieties, the black being the finest. 8. Lichens.— Iceland moss is the most important of the lichens. It is grown in the Arctic regions and used as a food, but it is very difficult of digestion. 9. Algce.—Irish moss is the most important of the algse. It is a form of seaweed which is used in invalid cookery.1 Digestion.—Carbohydrates are broken down and eliminated as C02 and H20. The various starches, dextrins, etc., are reduced to dextrose by the enzymes and as such are absorbed 1 Bailey, E. H. S.: Source, Chemistry and Use of Food Products. 42 CARBOHYDRATES and pass into the hlood stream. The blood from the intes- tines passes into the portal vein and is carried to the liver. In the liver and the muscle tissues is stored the reserve supply of carbohydrate material in the form of glycogen. It is readily reconvertible into dextrose and is available whenever the body needs this reserve fuel. If more carbo- hydrate is taken than is immediately needed, or than can be stored as glycogen, it is probably transformed into fat and stored as adipose tissue. Occurrence in the Body.—Carbohydrate material is formed as glycogen in the liver and muscles, exists as dextrose in the blood and is formed as lactose, or sugar of milk, in the mam- mary glands. Uses to the Body. —1. Carbohydrate is a body reserve in the form of glycogen. 2. It supplies heat and energy in an economical, readily digested and easily mobilized form. 3. An excess of carbohydrate is probably converted into adipose tissue. Dietetic Uses. —1. Strained carbohydrate cereals are used when there is any inflammation of the food tract. 2. Coarse carbohydrates are used to stimulate peristalsis when there is deficient motility. 3. Concentrated carbohydrates are given when high caloric diets are necessary, as in emaciation or during con- valescence. 4. Carbohydrates are restricted in obesity and diabetes. 5. Twice-cooked carbohydrates, as breadstuff's, are given in cases of digestive disturbance. 6. Fresh fruit, fresh vegetables and cereals in the diet are a protection against certain of the deficiency diseases. Examples: scurvy, beriberi, etc. DIETETIC USES 43 Foods Arranged Approximately According to Percentage of Carb ohyd rates. 1 5 per cent. 10 per cent. 15 per cent. 20 per cent.

Sources.—Fats are obtained from both the animal and the vegetable kingdom. In the animal, fats are formed in the connective tissues and in small amounts in the blood and surrounding certain of the abdominal viscera. Foodstuffs of animal origin which classify as fats are butter, bacon, cream, egg-yolk, cod-liver oil, suet, lard and bone marrow. Bone marrow is a highly nutritious and easily assimilated fat and is often added to the dietary of fevers of long dura- tion if the digestion is not impaired. It is valuable in anemia, as it contributes organic iron as well as hemoglobin and other blood-forming substances. It is obtained commer- cially from the short ribs of young growing cattle and is prepared in combination with glycerin. Fat is found in egg-yolk in the form of lecithin. Lecithin is combined with vitellin and is classified under the con- jugated proteins as lecitho-protein. Lecithin is a necessary constituent of every living cell. Commercially it is prepared from the yolk of the egg or from brain tissues. The fats of vegetable origin are found largely in seeds and nuts. They are almost entirely in the form of oils, and are easily digested. Examples of these fats are: olive oil, cottonseed oil, peanut oil and cocoanut oil. Classification.—Fats may be classified as: 1. Fixed or true fats, which leave a grease stain. 2. Volatile oils, which leave no stain. Flavoring extracts are examples of the latter. Fixed Fats.—The fats are made up of C H O, the O being small in proportion to the C and II. Fats may be CLASSIFICATION 45 called salts, since they are in the combination of a base and an organic fatty acid. The base with which the fatty acid unites is always glycerin, but the fatty acid varies. There are many of these salts, but those physiologically important are stearin, palmitin and olein. Animal fats are usually combinations of these several salts, the texture of the material indicating which salt is present in the greatest quantity. 1. The salts which classify as stearins are solid fats, white or light yellow in color. Tallow is an example of this form. These fats have a high melting point and are not as digestible as the fats with a melting point nearer the body temperature. The fatty acid in stearin is stearic acid. 2. The salts of the palmitin group are softer than the stearin fats and have a lower melting point. Butter is an example of palmitin. The fatty acid in palmitin is palmitic acid. 3. The oleins are oils at ordinary temperature, having a very low melting point. This makes them the more available as foods. Olein is composed of oleic acid and glycerin. It is interesting to note that all of these fats, melted, solidified and melted again, have acquired a slightly higher melting point. This makes them a little less easy of diges- tion. The following table indicates the extent of the utilization of these substances in the body in relation to the melting point of the fat: Melting point. Percentage Fat.1 ° C. loss in feces. Pure stearin 60 91-86 Stearin and almond oil 55 10.6 Spermaceti 53 31.0 Mutton fat 50-51 9.2 Lard 43 2.6 Pork fat 34 2.8 Goose fat 25 2.5 Olive oil fluid 2.3 1 Carter, Howe and Mann: Nutrition and Clinical Dietetics (Lea & Febiger), 46 FATS AND OILS Summary of Characteristics. —1. Fats are composed of C H O. Because of the fact that they contain only a small amount of O in proportion to their C and H they are some- times called the “hydrocarbons.” 2. They have a variable melting point. 3. True fats leave a grease stain. 4. The oils may be subjected to intense heat without burning, hence their value as cooking agents. 5. They are easily decomposed. Rancid fat gives a dis- agreeable odor, due to the separation of the acid from its base. 6. The stearins are colorless and tasteless, but the oleins have a dark yellow color and a characteristic taste. 7. They are insoluble in water. 8. They are valuable in cooking, since they act as carriers for other materials. Cookery of Fats.—Fats are considered more digestible uncooked than as hot cooked fats. The hot fat tends to penetrate the food mass and render it more difficult of digestion, while materials combined with uncooked fats are masticated and readily disintegrated. Fat that has been subjected to too intense a heat has undergone certain chemical changes, the products of which are irritating to the intes- tinal tract. Fats heated and resolidified are not as available food materials as before heating. Digestion of Fats.—Fats are emulsified and saponified in the process of digestion. Emulsification is a physical change while saponification is a chemical one. An emulsion is a fine physical subdivision of fat particles held in suspension in some favorable medium. Milk is an example of emulsified fat. In emulsion fat is already partially digested and will be readily split into fatty acids and glycerin. Fats so split are readily absorbed or their fatty acids inav combine with DIGESTION OF FATS 47 the alkalis of the bile and the pancreatic juice to form soft soaps, which in turn serve to promote the emulsification of unemulsified fats in the bowel. Subsequent to their absorp- Fig. 1.—Diet kitchen. tion the split fats are resynthesized. Cream or milk and butter, in combination with other foods, eggs and olive oil, are examples of desirable fats because they are easily digested. 48 FATS AND OILS Occurrence in the Body.—An average of one-fifth of the body weight is fat. Its storage, however, is not constant. The proteins are eliminated to the point of maintaining the nitrogenous equilibrium of the body. Carbohydrates are utilized only up to the carbohydrate limit of the individual; the mineral and the water content of the body remains fairly constant, but the utilization of fat varies. Adipose tissue is in the nature of a reserve fund drawn upon under starvation or illness. In excess it becomes a signal of danger. People of mature age and sedentary occupation should watch their weight and avoid the tendency to excessive increase. Fat-soluble A Vitamin.—This is found in cream, milk, egg- yolk, in yellow corn and butter. It is believed to be an anti- rachitic vitamin. Such foods are especially important in the diet of children, since bone formation is a rapid and neces- sary process at this age. The fat-soluble vitamin seems to withstand heat. Uses of Fat to the Body. —1. Fats that are not oxidized for energy production are stored chiefly in the connective tis- sues. The body is inclined to utilize its carbohydrate supply for its energy requirement and reserve its storage fat. 2. The organs of the body are frequently protected by layers of fat. These act as non-conductors of heat and therefore as a protection against cold. 3. Fats promote growth and certain fats aid the body in its utilization of the mineral supply in the construction of the hard parts of the body. 4. The fats with a low melting point are very completely utilized forms of food. 5. Fats are mild laxatives and lubricate the alimentary canal. Dietetic Uses. —1. Fats are useful in the diet of children. They contain growth-promoting vitamins which are essen- DIETETIC USES 49 tial to their development. Children, on account of their great activity, require a high caloric diet and fats supply a concentrated food. 2. Diabetic patients are given a diet high in fat to satisfy the caloric requirement. The carbohydrates are restricted in this condition and the fats supply caloric values in their place. 3. In rickets and other deficiency diseases the fat soluble A containing foods are indicated. 4. In tuberculosis, anemia, during convalescence in wast- ing diseases and in visceral optoses, finely divided fats are given to force the feeding of the replacing tissues for those damaged by disease. 5. Fats are required by those exposed to severe cold or doing manual labor. G. Certain oils are laxative and are given for this purpose. 7. Fats in excess cause gastritis and diarrhea. 8. Fats are restricted in disorders of the liver, as the bile is important in the digestion and absorption of fats. BIBLIOGRAPHY. Pettibone: Physiological Chemistry (Mosby).

Source.—Proteins are built in the vegetable tissues; their nitrogens are derived from the soil or air. Proteins in the diet are secured from vegetable foods which have constructed their own protein or from animal food built up from the same vegetable proteins. Protein food comes from: 1. Animal Foods: meat, fish, fowl, eggs, milk and cheese. 2. Vegetable Foods: legumes (peas, beans, lentils), grains, and the rapidly growing part of the organism as buds or sprouts. Composition.—Proteins are very complex and differ greatly in composition. They are difficult to study as living proteins, because they differ from the products they break into as soon as life leaves the body. The average protein is com- posed of carbon, hydrogen, nitrogen, oxygen, sulphur and traces, sometimes of phosphorus and iron. Description.—In the living organism, proteins are in liquid or semisolid form. Under certain conditions products of protein metabolism are imperfectly eliminated and accumu- late in the body. For example, urea and creatin in nephritis and uric acid in gout. Classification of Proteins.—A classification of proteins adopted by the American Society of Biological Chemists is as follows: 1. Simple proteins. (a) Albumins: in egg white, milk, blood. (b) Globulins: myosin, fibrinogen, fibrin. (c) Glutelins: gluten, avenin. CHARACTERISTICS 51 (d) Protamins: gliadin, zein. (e) Albuminoids: keratin, collagen, elastin. (/) Histones: globin of hemoglobin. 2. Conjugated proteins are proteins linked with some non- protein substance. (a) Glyco-proteins: mucin and mucoids. (b) Phospho-proteins: casein and vitellin. (c) Chromo-proteins: hemoglobin (blood). (d) Nucleo-proteins: nuclei of cells. (e) Lecitho-proteins: vitellin. 3. Derived Proteins.—These are formed from other pro- teins, physiologically by ferment action, involving a cleavage of their molecular form. (а) Meta-proteins. (б) Proteoses. (c) Peptones. (d) Peptids. (e) Amino-acids. Test for Proteins.—To egg albumen add concentrated nitric acid and warm. A yellow precipitate results. Characteristics. —1. Simple proteins are soluble in cold water or cold salt water. 2. Gelatins absorb cold water and are dissolved by hot water. 3. Hot water coagulates simple proteins. 4. Dry heat coagulates proteins. Proteins are rendered relatively indigestible by coagula- tion under heat. They take on a tough, tenacious quality and become mechanically difficult unless reduced to powder. It is true that in the preparation of meat the outside surface is exposed to intense heat for a short time, but the heat is then rapidly reduced. This sacrifices the outside surfaces, but serves to retain the juices which, being converted into 52 PROTEINS steam, render the meat more tender. The general rule for the cooking of proteins calls for a moderate temperature. Putrefaction.—Proteins are susceptible to bacterial action. This is a form of decomposition and very dangerous products may result. Protein foods must be carefully watched for indications of decomposition. Uses in the Body. —1. To build and repair tissues which contain nitrogen. 2. To build up and store (transitorily) nitrogenous material. 3. To supply the protein constituents of body fluids, including blood and lymph. 4. To produce energy under emergency, involving an exhaustion of carbohydrates or fat storage. Dietetic Uses. —1. To repair tissue waste in destructive diseases, as tuberculosis. 2. To repair the tissues in convalescence from continued or acute disease. Precautions. —1. An excess of protein food may cause digestive disturbances. Proteins of choice in invalid-feeding are those of milk and eggs, as they do not contain stimulating extractives and are in easily digested form. 2. Proteins are restricted in acute kidney conditions, when the products of protein metabolism fail, more or less, of elimination. 3. In hypertension the diet in protein is kept low, barely maintaining a nitrogenous equilibrium. The purins are restricted. 4. In skin and asthma cases, skin tests may be used to determine protein sensitization. Offending proteins may be eliminated from the diet and avoided as a protection against future attacks. The Digestion of Proteins.—The changes in digestion are both physical and chemical and are somewhat influenced by CHEMICAL DIGESTION OF PROTEIN 53 the method of cooking to which the food has been sub- jected. Mastication is important in breaking up the food mass, so that the digestive juices may more thoroughly penetrate it. It serves, also, to break up the connective tissue. Chemical Digestion of Protein.—Protein food passing into the stomach is penetrated by the gastric juice. Gastric digestion does not begin until the food has been neutralized by the hydrochloric acid of the secretion. The enzyme pepsin splits protein to proteoses and peptones, intermediate products of protein digestion. Trypsin, a much stronger ferment of the pancreatic juice, carries the digestion of pro- teins to completion in the small intestine. It splits proteins into proteoses, peptones, if not already so converted, and splits these into polypeptids and amino-acids. Erepsin, in the intestinal juice, assists the digestion by also converting the peptones and polypeptids into amino-acids. BIBLIOGRAPHY. Hutchinson: Food and Dietetics (Wm. Wood & Co.).

Factors Which Control the Food Requirement.—There are several factors which determine the food requirement of the body. The quantity of food necessary to maintain nutrition is influenced by age, sex, occupation, climate, weight and the extent of body surface. Functional activity involves the expenditure of energy. Certain forms of function are constant or continuous, as digestion, respiration, circulation and the various changes of metabolism. The energy to produce all forms of work is supplied by the food. Foods are defined as substances, which when taken into the body build and repair tissue and supply the body with energy. The conversion of food into tissue involves a series of chemical changes which liberate heat. The fuel value of food is calculated in calories. A calorie is the amount of heat required to raise the temperature of 1 kilogram of water to 1° Centigrade. Caloric Value of Food.—To determine the caloric value of food, multiply its fat, carbohydrate and protein content, converted into grams, by the number of calories yielded by each gram. 1 gram of protein yields four major calories. 1 gram of carbohydrate yields four major calories. 1 gram of fat yields nine major calories. A kilogram is 1000 grams and equals 2.2 pounds. For practical purposes, consider 30 grams equal to 1 ounce. WEIGHT 55 Example: Caloric Food. Amount. Protein. Fat. Carbohydrate, value. Butter . . 30 gm. 1.0% 85.0% 0% 0.3 gm. 25.5 gm. X4 X9 1.2 229.5 230.7 Another method which may be used is: divide the caloric value per pound by 10, obtaining the caloric value per ounce; dividing this again by 30 to obtain the caloric value per gram. Example: Butter 3605.0 calories per pound. 225.0 “ “ ounce. 7.5 “ “ gram. Weight.—Age, weight and height are considered together. Weight is the index to the condition of the body and the food requirement is indicated by its loss or increase. A table giving the number of calories allowed for each kilogram of body weight is as follows: 1 to 6 months 100 6 to 12 “ 85 1 year 70 2 years 70+-65 3 to 7 years 65 7 to 12 “ 60 12 years to maturity: (a) Period of structural activity 50 (b) Period of functional activity: For female 55 For male 60 (c) Maturity 37-55 (d) Old age 35-40 In old age the body needs more fuel in proportion to its weight than at maturity. An estimate, indicating the varying daily caloric require- 56 THE CALORIC VALUES OF FOOD merits according to the amount and form of functional activ- ity, as computed by Tigerstedt,1 is: 2001 to 2400 calories (shoemaker). 2401 to 2700 calories (weaver). 2701 to 3200 calories (carpenter). 3201 to 4100 calories (farm laborer). 4101 to 5000 calories (excavator). 5000 calories (lumberman). Climate.—Climate has much to do with both the quality and the quantity of the food required. It is a recognized physiological fact that the digestion is less robust in spring than during the winter months. With the passing of the cold weather there is a relative lack of interest in food. This should be met by a radical change of diet. The spring diet should be lighter and easier of digestion and should contain green vegetables and fresh fruits. These foods contain valuable minerals. As the mild weather approaches the body has less need of the fuel foods, which make it possible to decrease the amount of fats and heavy carbohydrates. In warm climates especially water is an important food. Because of the rapid evaporation of moisture from the skin, it is necessary to meet the loss with a large supply of fluid food. In these climates are found the succulent fruits and vegetables, which consist largely of water, Nature seemingly adapting the food produced by the locality to the needs of its people. In the temperature zone the people do more active work than the less robust people of the south, and here, conse- quently, are used the more nutritious fruits. These carbo- hydrate foods are the most active. They do not represent 1 Excerpt from a Text-book of Human Physiology, translated by John Murlin, M.D., p. 141 (courtesy of D. Appleton & Co.). SEX 57 however, the largest energy producers, as the fats represent, weight for weight, more than twice the amount of heat that the proteins and carbohydrates contribute. The value of fats as heat producers has been established. Arctic travelers carry a supply of chocolate which, aside from the fact that it does not freeze and does not require cooking, contains a large supply of fat. Age.—During the early years of life the demand for food is high because of the rapidity of growth. A child under two years of age requires proportionately twice the amount of food that the adult needs. The food requirement is relatively high during childhood, gradually decreasing according to the rate of growth. Atwater states that a child under two years requires three-tenths the food of an adidt man at active muscular work; that a child of two to five years requires four-tenths the food of an adult man at active muscular work; that a child of six to nine requires one-half the food of an adult man at active muscular work; that a boy ten to eleven or a girl ten to twelve requires six-tenths the food of a man at active muscular work; that a woman at light work, a boy of twelve or a girl of thirteen to fourteen requires seven-tenths the food of a man at moderately active muscular work; that a man at light muscular work or a boy fifteen to sixteen years old requires nine-tenths the food of a man at moder- ately active muscular work, and that a man at hard muscular work requires one-fifth more food than a man at moderately active work. Sex.—Caloric need is influenced by the amount of body surface, the tall individual losing more heat through radia- tion than the short, heavy one of the same weight. Women lose proportionately to weight and size more heat by radia- 58 THE CALORIC VALUES OF FOOD tion than do men; and also because their body processes are more rapid than those of men. Although women require eight-tenths the amount of food that men require, yet, weight for weight, their demand for food is greater. No one factor can control the caloric requirement of the individual, but weight, sex, occupation, build, age and climate must all be considered in providing an adequate diet.

These should be solved hand-in-hand to secure the most desirable results. To have a scientific knowledge of cooking we must understand: 1. The composition of food materials and their uses in the body. 2. The general principle of cooking applicable to each class of foods, so that we know what kind of heat to apply, how much and for how long a time. 3. The best methods of keeping foods from decomposing and of detecting decomposition when it has already set in. 4. The economical use of cooking utensils, fuel, etc., so that time and money may be saved. 5. The proper proportions of food materials used in any given recipe. Reasons for Cooking. —1. That food may be rendered more digestible. 2. That harmful bacteria may be destroyed. 3. That fiber in vegetable foods and connective tissue in animal foods may be softened and broken down. 4. That food may be made more attractive. 5. That flavor be developed. Esthetic Values of Food.—The esthetic values of food are enhanced: 1. By the development of flavor in food. 2. By the appropriate service of food. SELECTION OF FOOD 67 3. By a suitable color scheme. 4. By the aid of decoration. The esthetic value of food may be enhanced or impaired in the cooking process. This applies to all cookery, but it must be emphasized in the preparation of food for the sick, in whom appetite is variable and for whom every effort must be made to make food service attractive. Selection of Food.—Fresh fruit and vegetables lend variety and are nicely decorative. Salads give a note of color and desserts may be so served as to be ornamental.

Fahrenheit is used in cookery in regulating the tempera- ture of a room or in taking body temperature. The freezing point is 32° above zero. The boiling point is 212°. 2. Centigrade is used by most scientists. The freezing point is zero. The boiling point is 100°. To Change from One Scale to Another. Above 0° C. or 32° F. F. to C. Subtract 32, multiply by 5, divide by 9. Example: Change 212° F. to C. 212°—32° = 180° 180° X f = 100° C. C. to F. Multiply by 9, divide by 5, add 32. Change 100° C. to F. 100° X | = 180° 180° + 32° = 212° F. CARE OF THE LABORATORY 69 Between 0° and 32° F. and 17.75° and 0° C. F. to C. Subtract from 32, multiply by 5, divide by 9. C. to F. Multiply by 9, divide by 5, subtract from 32. Rules for Measuring. —1. All measurements are to be made level unless otherwise directed in the recipe. 2. In measuring solid materials with a teaspoon, table- spoon or standard measuring cup, fill the measuring utensil with the material and then level off with a knife. 3. Half a spoonful is obtained by dividing a level spoonful lengthwise through the center. 4. A quarter of a spoonful is obtained by dividing a half spoonful through the center crosswise. 5. An eighth of a spoonful is obtained by dividing a quarter spoonful diagonally. G. A third of a spoonful is obtained by dividing a level spoonful twice crosswise. Care of the Laboratory. — Routine Methods of Cleaning Gas Stoves.—Ordinary brown wrapping paper, newspaper or tissue paper, cut in squares 6" x 6", can be used to remove the deposit made by water spilled on the stove. Kitchen Utensils.—Kitchen utensils may be kept in good condition with the liberal use of hot water, soap and ammonia or washing-soda solution (hot water 1 gallon and sal soda 1 pound). Sapolio may be used when substances are burned on or when the utensil is smoked. Soda solution also removes burnt substances. In cooking cocoa or milk, if utensils are well rinsed with cold water first the coating is easier removed. Iron Rust.—To remove iron rust from iron or steel, scrub with sweet oil and emery powder; coat with sweet oil and allow it to stand twenty-four hours. To Remove Grease from Unpainted Wood.—Apply soda dis- solved in cold water. Wash off with hot water. Apply soap powders. 70 FOOD PREPARATION To Remove White Spots from Polished Wood.—Sponge off with spirits of camphor; follow by rubbing with oil and turpentine. To Remove Ink Stains from Wood.—Apply some absorbent starch, blotting paper, etc. When no more ink is absorbed, rub spots with lemon pulp, javelle water or common salt. Wash off with cold or tepid water. Painted, Varnished and Oiled Woodwork.—Clean with weak solution of ammonia. Three per cent solution: 30 cc (2 tablespoonfuls) ammonia 1000 cc (1 quart) water. Wash a small surface at a time and wipe dry with cloth. White paint should be cleaned with whiting applied with moistened cloth or sponge. Clean a small surface at a time and wipe dry immediately. Porcelain.—Remove grease and dirt with kerosene; remove kerosene with hot water and soap. Iron stains may be removed from porcelain by rubbing the spot with a 10 per cent solution of hydrochloric acid, removing the acid with sodium carbonate (washing soda), 5 per cent solution. 3 tablespoonfuls soda ( = 50gms.) 1 quart water (=1000 cc) Glass Windows, etc.—Wash with kerosene and water (1 tablespoonful kerosene to 1 quart water); or cover glass with coating of whiting or Bon Ami, allow to dry and then wipe off and polish. Nickel.—Nickel may be kept bright by frequent washing with hot water and soap. It may occasionally be rubbed with sodium bicarbonate and kerosene made into a paste. Copper and Brass.—Use formula: kerosene, 1 pint; whiting 4 ounces; oxalic acid, 2 teaspoonfuls; alcohol, 4 ounces. This preparation is very efficient. Rules for Washing Dishes. —1. Collect all dishes to be washed, scrape them clean, wipe off grease with soft paper and pile dishes of a kind together. CARE OF SINK 71 2. Soak dishes that have held eggs, milk or starchy mate- rials in cold water. Those that have held sugar in hot water. 3. Have two pans of hot water, one for washing dishes and one for rinsing. 4. Have a clean place ready for dry dishes. 5. Be sure that your dish cloth is perfectly clean and have a separate one for china and for the kitchen utensils. G. Dishes should be washed in the following order. (а) Glass: wipe directly from soapy water to make them shine. (б) Silver: same as glass. (c) Fine china: rinse well and wipe. (■d) Heavier china: rinse well and wipe. (e) Small kitchen utensils: knives and forks should be scoured with brick, sapolio or kitchen cleanser. (/) Large kitchen utensils, rinse well; dry thoroughly before putting away. 7. Do not wet the cogs of egg beaters. 8. Wash tea and coffee pots carefully with clean, hot water; rinse well. 9. Change dish water when necessary during washing process. 10. Do not let soap soak in dish pan. 11. Wash dish pan thoroughly; wipe dry before putting away. 12. Rinse out dish towels and cloths and hang in the sun, if possible, after every washing. Care of Sink. —1. A good porcelain sink with open plumb- ing is the easiest to keep clean. 2. Keep an enamel sink strainer in the sink and pass all waste material through it. After each meal when you clean the sink, empty strainer, wash well and wipe dry. 3. After every meal wash sink thoroughly with hot soapy water. Remove stains with Dutch Cleanser. 72 FOOD PREPARATION 4. Once a week pour a strong solution of sal soda cup soda to 2 quarts hot water) down the sink pipe. Flush with boiling water. Care of the Refrigerator.—The refrigerator must be kept perfectly clean or it becomes a good breeding place for germs. The following points, if carefully followed, will ensure this perfect cleanliness: 1. Never put hot food or food with strong odors into the ice-box. 2. Keep perishable materials like butter, eggs and milk in the lower part of the box, as the current of air is toward the top. Keep foods with stronger flavors, if necessary on top shelves. 3. Put leftover foods away in the smallest utensils possible. 4. Watch carefully each day for any signs of decomposition in food and remove at once. 5. Keep the ice-box cold and at an even temperature. Do not let all the ice melt before box is replenished. This warms the box and requires a large quantity of ice to cool it. 6. If anything is spilled in the ice-box wipe it up at once. 7. Once a week remove contents of box; remove shelves and wash in hot soda or borax water; put shelves to dry in a warm place or in the sun. Wash inside of box carefully and dry well. Pour hot soda water down the trap and see that it is free from sawdust or any accumulation from the ice water. 8. If ice water appears in the bottom of your refrigerator your drain pipe is clogged up. Clean out the drain with a bottle brush or skewer, then flush with hot soda water as directed. Care of the Garbage Can. —1. The garbage can should be kept as clean and inoffensive as possible. 2. ITse a galvanized can with a tight-fitting cover. 3. Place garbage can outside if possible. DUTIES OF HOUSEKEEPERS IN DIETETIC CLASSES 73 4. Empty garbage from the kitchen after each meal. Do not let it stand in kitchen even in winter. If there is no rule to the contrary in your locality, place the garbage in a clean paper before depositing it in the can. 5. The garbage can may be lined with clean newspaper. This makes it easier to keep clean. 6. All liquids must be strained from refuse before placing it in the can. 7. Once a week scald out the can with boiling water to which some disinfectant or deodorant has been added. Dry in the sun with cover off. Duties of Housekeepers in Dietetic Classes. —1. Have gen- eral oversight of class cooking at the large range. Light the oven when required and turn it off when it is no longer needed. 2. Clean gas stove, if necessary, after class period. 3. Responsible for condition of laboratory sink. Keep it free from dishes during class period and distribute such dishes and utensils to members of the class for cleaning. Wash sink and drain board, polish faucets and leave this part of the room in perfect condition. 4. Keep supply table in order during and after class. Clear table when supplies are no longer needed and wash with hot water and soap. 5. Leave refrigerator in order. Sweep laboratory if neces- sary. CHAPTER XI. BEVERAGES. Beverages as a class are valuable because of the water they contain. This is especially true during acute illness and during convalescence from acute illness, as the water helps to rid the body of the toxins resulting from infection; it tends toward the better digestion of food; and it provides for the restoration of fluid lost to the body in the course of the dis- ease. Besides, each class of beverages has a particular func- tion or functions to perform in the body. Beverages may be divided into four groups: 1. Acid B ever ages.—Acid beverages, fruit juices combined with plain or carbonated water. These are not only refresh- ing, but they furnish valuable salts and tend to promote the alkalinity of the tissues. Example: orangeade. 2. Stimulating Beverages.—Stimulating beverages, reliev- ing fatigue, warming the digestive tract and preparing it for the reception of solid food. They have no food value in themselves, but are usually accompanied by cream and sugar. Examples: tea, coffee, broth. 3. Farinaceous Beverages.—Farinaceous beverages, which furnish some values in the form of starch. They are cooked, thinned, strained cereals, served as gruels. They have a sedative effect on the walls of the alimentary canal and give variety to a limited diet. They may be diluted with cream and butter, giving them a higher caloric value. Example: oatmeal gruel. 4. Albuminous Beverages.—Albuminous beverages, these are high in food value and form a means of giving food in a RECIPES 75 highly concentrated form. Those made with the entire egg are especially high in food value, while those made with the white alone are simpler and easier of digestion. Example: fruit albumin, eggnog. RECIPES. Lemonade. 1 lemon; 2 teaspoonfuls sugar; 1 cup boiling water. Wash the lemon, roll until soft. Cut in two with a silver knife. Squeeze out the juice; add sugar and boiling water. Cover well and chill. PlNEAPPLEADE. Add to recipe for lemonade: | cup of pineapple pulp; cup boiling water; sugar to taste. Strain before serving. Pick over moss and soak in cold water to cover for half an hour. Remove from water, add 1 cup of cold water and cook in the top of a double boiler about twenty minutes. Add this to lemonade. Any other fruit drink may be treated in the same way. Irisii-moss Lemonade. Bran Water. Soak l cup of bran in 1 cup of cold water overnight and strain. Add to lemonade. Vichy or Soda Water. Stir J teaspoonful Vichy powder or \ teaspoonful soda into lemonade just before serving. Do not have the glass too full. Serve immediately. This has a slightly laxative effect. 76 BEVERAGES Cooked Eggnog. 1| cups of milk; 1 egg. Heat the milk in a double boiler. Add the beaten egg. Stir until mixed and remove from fire. Season and chill. This serves to disguise the egg if the patient objects to the raw-egg flavor. Eggnog. 1 egg; 2 teaspoonfuls of sugar; f cup of milk; f teaspoonful of lemon extract; few grains of salt. Beat the egg until foamy; add sugar and milk and then flavoring extract. Tea. 1 teaspoonful of tea; 1 cup of boiling water. Scald teapot, which should be of silver, crockery or granite ware. Put in the tea; add boiling water and let it infuse for five minutes. Do not boil. Tea, like coffee, contains tannin, a harmful astringent; thein, a stimulating property; and essential oils, which give it flavor. Boiling or too long steeping brings out the tannin, which is the undesirable thing. Coffee. 2 tablespoonfuls of coffee; | cup of cold water; \ egg; 1 cup of boiling water. Scald the coffee-pot. Wash the egg, break and beat slightly; dilute f egg with 2 tablespoonfuls of cold water and mix with the coffee. Add the boiling water and stir. Boil three minutes. Let it stand over low flame for ten minutes. Add 1 tablespoonful of cold water. Serve. Coffee contains a stimulating property, caffein; a harmful tannin, which is bitter to taste and retards the flow of the RECIPES 77 digestive juices; and essential oils, which give each kind of coffee its characteristic flavor. Breakfast Cocoa. 1 pint of scalded milk; 3 tablespoonfuls of cocoa; § cup of boiling water; 2 tablespoonfuls of sugar. Mix the cocoa and sugar in a saucepan. Stir in the water gradually and boil for five minutes. Add the milk and cook for five minutes, or until smooth, in a double boiler. Beat well with a Dover beater. | square Baker’s chocolate; 1 cup of milk; | tablespoonful of sugar; f cup of boiling water; salt. Scald the milk. Melt chocolate in a small sauce-pan placed over hot water. Add sugar, salt and gradually boiling water; when smooth, place on the range and boil for one minute. Add to the scalded milk; beat with Dover egg beater and serve in chocolate cups with whipped cream. The cocoa seeds or beans are enclosed in a pod, each pod containing from twenty to forty beans. These beans are fermented for several days to develop their flavor, then dried and roasted and finally ground fine. In making cocoa some of the fat of the bean is removed after grinding. In the making of chocolate, it is put up in the raw or bitter form or is flavored and sweetened before running it into the molds. Both have a slightly stimulating effect, because of a mild principle, theobromin, similar to caffein, which they contain. Chocolate. Barley Water. 1| teaspoonfuls of pearl barley; 2 cups of cold water. Soak the barley in cold water overnight. Drain and add 78 BEVERAGES fresh water. Boil in the water until quantity is reduced to two-thirds of a cup. Strain, serve hot or cold or use to dilute other gruels. This may be seasoned with salt, fruit juice or wine. Arrowroot Gruel. Dissolve J teaspoonful of sugar and \ teaspoonful of salt in a cupful of water. Mix \ tablespoonful of arrowroot flour with a little cold water and combine with mixture. Boil for twenty minutes, stirring constantly; then add a cupful of milk, bring to the boiling point, strain and serve hot. Oatmeal Gruel. I cup of oatmeal; 2 cups of water; § teaspoonful of salt. Boil directly over the fire for thirty minutes. This will probably cook down to one-half. Strain; add 1 cup of milk, re-heat and serve in a china cup. Gruel is colorless and needs a gaily colored cup. Flour Gruel. Proceed as in making arrowroot gruel, using instead a tablespoonful of wheat flour. Flavor with lemon juice, cin- namon, nutmeg or vanilla. Farina Gruel. Proceed as above, using instead a tablespoonful of farina, and boil for about ten minutes before adding milk. Cracker Gruel. Use 2 tablespoonfuls of cracker crumbs and proceed as above. Cook only two or three minutes and do not strain. RECIPES 79 Chocolate Shake. Combine \ cup of cocoa and 2 cups of water. Boil for twenty minutes. Add 1 cup of sugar and boil for five minutes. Add J teaspoonful of vanilla and chill. For a chocolate shake, put 2 tablespoonfuls of syrup, 1 egg, cup of milk and i cup of crushed ice in a Mason jar. Instead of the crushed ice, 2 tablespoonfuls of ice-cream may be used. Shake well, strain and serve cold. Salt crackers may be served with the beverage. In some cases it is well not to serve so heavy a beverage, and then only the white of the egg may be used. Fruit Albumin. Combine the juice of | an orange; \ a lemon; \ teaspoonful of sugar; white of 1 egg; | cup of chopped ice. Shake in a covered jar. Serve very cold. Albuminized Tea. Rinse out teapot with boiling water. Put in tea, pour on boiling water. Let stand in a warm place for five minutes. Pour off the liquid, add 1 egg white to each cup of liquid. Chill liquid before adding egg white. Albuminized drinks are used chiefly in cases of acute stomach and intestinal disorder. They are nutritious and easily assimilated. For infants, use 1 egg white to 1 quart of chilled boiled water. Fruit Punch. 2 cups of water; chopped rind of lemon; 1 dozen straw- berries; 2 quarts Apollinaris; 2 cups of sugar; juice of 8 lemons; 1 can of pineapple; \ pound of candied cherries. Boil the water, sugar and lemon rind for ten minutes. 80 BEVERAGES Strain, cool, add lemon juice and chopped pineapple. Place a large square of ice in punch bowl. Pour mixture over it. Add Apollinaris water last. Fruit Punch. 4 cups of cold water; 2 cups of chopped pineapple; \ cup of lemon juice; 2 cups of sugar; 1 cup of orange juice. Boil water, sugar and pineapple for twenty minutes. Add the fruit juice, cool, strain and dilute with ice water. Any of the following may be used: box strawberries or raspberries, mashed. 1 cup of cherries. \ cup of grapefruit juice. 2 cups of peaches mashed. CHAPTER XII. CREAM SAUCES. Cream or white sauces are of two kinds, depending upon their use in cookery: 1. Medium cream sauce, used for cream soups and scal- loped dishes. 2. Thick cream sauce, used for vegetables, fish and meat. Method of mixing materials. 1. Scald milk in double boiler. 2. Melt butter in sauce pan. 3. Add flour to melted butter. 4. Add scalded milk slowly. 5. Stir mixture until smooth and thick in double boiler. 6. Add seasonings. 7. Use wooden spoon to stir the mixture. Medium Thin Sauce. 1 tablespoonful of butter; 1 cup of milk; 1 tablespoonful of flour; j teaspoonful of salt; few grains of pepper (white or paprika). Thick Cream Sauce. 2 tablespoonfuls of butter; 1 cup of milk; 2 tablespoonfuls of flour; | teaspoonful of salt; few grains of pepper (white or paprika). Hot Sandwich Roll. Stale finger rolls may be used. Cut center from rolls and fill them with creamed mushrooms. Set in broiler of gas range after filling and toast top of roll. Garnish with parsley. 82 CREAM SAUCES CREAM SOUPS. Cream soups are combinations of thin white sauce and strained vegetable pulp. They form a light and easily digested form of food for the sick. The vegetables most suitable for use in cream soups are: potatoes, peas, celery, tomatoes, beans, asparagus, corn and spinach. Onions are used for flavoring if desired. Food Values.—Cream soups are high in food value. The milk or cream furnishes protein and fat in a digestible form, while the vegetables furnish starch and mineral salts. These soups are not suitable for use at a heavy meal, but for luncheon or extra nourishment between meals. General Directions for Preparing Cream Soups. —1. Cook the vegetables in boiling salted water until soft enough to press through a sieve. 2. Make a white sauce by melting the butter, adding the flour and then the scalded milk slowly. Cook the white sauce thoroughly, stirring it during cooking. This is neces- sary to cook the starch in the flour. 3. Combine the cooked white sauce and the cooked and strained vegetable pulp; add seasoning, strain if desired and serve at once. After standing for any length of time, cream soups are apt to separate. Cream of Celery Soup. 1 cup of milk; 1 tablespoonful of flour; 1 tablespoonful of butter; £ teaspoonful of salt; 1 small slice of onion; £ cup of celery; 1 cup of boiling water; pinch of paprika. Cook the celery, cut into small pieces, in boiling water until tender. Let the water boil away toward the end of the cooking. Make the white sauce; combine with it the cooked CREAM SOUPS 83 celery, put through a vegetable strainer; add the seasonings and serve at once. A spoonful of whipped cream may be put on top for a garnish. Cream of Corn Soup. 1 cup of milk; 1 tablespoonful of flour; 1 tablespoonful of butter; 1 cup of cold water; \ teaspoonful of salt; pinch of paprika; | cup of corn; small slice of onion. Cook the onion, corn and cold water together for about twenty minutes. Make a white sauce by melting butter, adding flour and then scalded milk slowly, cooking until smooth and thick. Strain the corn and add to the white sauce. Mix well, add the seasonings and serve. Cream of Tomato Soup. 1 cup of milk; 1 tablespoonful of butter; 1 tablespoonful of flour; 1 teaspoonful of sugar; | cup of tomato; | teaspoonful of salt; pinch of pepper; | teaspoonful of soda. Heat the tomato and the sugar together. Make the white sauce by melting the butter, adding flour and then scalded milk slowly. Mix well and serve as soon as possible, as it is apt to separate. Use whipped cream or finely chopped parsley for a garnish. Cream of Spinach Soup. 1 tablespoonful of chopped cooked spinach; § cup of milk; 1 tablespoonful of butter; f tablespoonful of flour; | tea- spoonful of salt; pinch of paprika. Add the spinach to the milk and bring it to the scalding point. Melt the flour and the butter in the double boiler; add milk mixture to them, mix well; add the seasonings, strain and serve. 84 CREAM SAUCES Rice Soup. tablespoonfuls of rice; 1| tablespoonfuls of butter; 1 stalk of celery; \ teaspoonful of salt and pepper; 2 cups of milk; \ small onion; f bay leaf. Scald milk, add well-washed rice and cook in double boiler for thirty minutes. Melt butter; add sliced onion; do not brown; then the celery and rice with the milk; add bay leaf, cover and let stand on back of range. Cream of Pea Soup. 1 cup of milk; 1 tablespoonful of butter; | tablespoonful of flour; | cup of canned peas; f teaspoonful of salt; few grains of pepper; \ teaspoonful of sugar; \ cup of cold water. Drain the peas and rinse them thoroughly; add the sugar and cold water and simmer for ten minutes. Rub through a sieve; add to the white sauce, made by melting butter, adding flour, and then scalded milk slowly. Cook until thick and smooth. Add seasonings; strain into a hot cup and serve at once. Cream of Potato Soup. 1 cup of milk; 1 small slice of onion; \ cup of mashed potato; few grains of celery salt; \ tablespoonful of butter; l teaspoonful of salt; few grains of pepper. Scald the milk and the onion together. Strain the milk slowly into the potatoes; add the butter and the seasonings; stir until well mixed; heat and strain' into a hot cup. A little parsley may be added for a garnish. Cream of Asparagus Soup. | cup of asparagus tips; 1 cup of milk; 1 tablespoonful of butter; 1 tablespoonful of flour; § teaspoonful of salt; few grains of pepper. CREAM SOUPS 85 Cook the asparagus tips in a little water until tender. Strain them, add to the milk; melt butter, add flour; then milk and asparagus slowly. Add the seasonings and the yolk of egg well beaten. Let the mixture cook for two minutes after the egg is added; then strain it through a sieve before serving. A little whipped cream may be used for a garnish, or beaten in before serving. Cream of Cauliflower Soup. 1 cup of milk; | tablespoonful of butter; f tablespoonful of flour; | cup of cooked cauliflower; J teaspoonful of salt; pinch of paprika. Melt the butter, add flour and then scalded milk slowly. Add cauliflower, chopped finely. Stir constantly until thick and smooth; add seasonings; strain and serve. Oyster Stew. 1 cup of oysters; \ teaspoonful of salt and pepper; cups of milk; 1 tablespoonful of butter. Scald the milk. Put oysters in strainer over the bowl; wash carefully with as little water as possible. Pick over oysters to remove particles of shell. Heat the liquor strained from oysters to the boiling point; strain through cheese- cloth. Add liquor and oysters to scalded milk; season and serve immediately. CHAPTER XIII. EGGS. Food Value.—The egg represents a concentrated and a fairly ideal form of food. Aside from supplying protein and fat, the egg is rich in lime, iron, sulphur and other minerals. Digestibility.—Cooking may impair or improve the food value of eggs. Raw egg white does not stimulate the flow of the digestive juices and is not considered as digestible as an egg cooked at 160° F. Cooking at a higher temperature densely coagulates the albumen and lessens its digestibility. An egg cooked at too high a temperature requires approxi- mately twice the time for digestion that an egg cooked at an ideal temperature does.

Pack in sawdust, salt or bran, small end down. 3. Put up in water glass. 1 Eggs and Their Uses as Food, Farmers’ Bulletin, No. 128. This table shows that the fat is found in the yolk. It is in the form of lecithin. The protein is in the form of albumin and globulins. COOKERY OF EGGS 87 COOKERY OF EGGS. Soft-cooked or Coddled Eggs. Put the egg in one pint of boiling water, cover. Remove from the fire and let it stand eight minutes. Baked Eggs. Break egg into a well-buttered cup or casserole; sprinkle with salt, dot with teaspoonful of butter, add f tablespoon- ful of cream. Bake in pan of hot water in moderate oven until white is set. Egg Nest. Toast bread. Separate egg. Beat white to a froth; add salt. Spread toast with butter and put white of egg on in shape of nest. Make a depression in center, put in j tea- spoonful of butter and drop in yolk. Cook in moderate oven three or four minutes. This may be served with tomato sauce. Poached or Dropped Eggs. Toast a square or round of bread. Break egg into a dish, then drop into a shallow pan two-thirds full of boiling salted water. When there is a film on top and white is firm, remove egg to toast, using a skimmer. Garnish. Creamed Eggs. Beat egg until light, add \ cup of milk, a little salt and 1 teaspoonful of melted butter. Put into the top of a double boiler and stir constantly until mixture thickens. Serve on toast or hot rice. 88 EGGS Foamy Omelet. Separate egg and beat white to a froth. Beat yolk until light, add 1 tablespoonful of milk; salt and pepper to taste; lightly fold in the white. Put 1 tablespoonful of butter into hot omelet pan; when melted, add egg mixture. Gently shake pan so that egg will not adhere to it; loosen edges with spatula and when delicately brown on bottom, set pan in hot oven one or two minutes, to dry omelet on top. Fold omelet half over and serve immediately. Chopped meat, parsley or prepared sauce may be spread on omelet before folding. CUSTARDS. Soft Custard. 2 cups of scalded milk; 2 tablespoonfuls of sugar; § tea- spoonful of vanilla; 3 egg yolks; | teaspoonful of salt. Beat eggs slightly, add sugar and salt, stir into hot milk slowly; pour into double-boiler. Cook, stirring constantly until thick enough to coat spoon. Strain and stir in vanilla. If custard begins to curdle, put top of double boiler in cold water. Beat mixture with Dover egg-beater. Baked Custard. 1 quart of milk; 4 to 6 eggs; | cup of sugar; f teaspoonful of salt. Beat eggs and stir in dry ingredients and then hot milk. Pour into buttered molds. Set in pan of hot water. Bake in moderate oven for twenty to thirty minutes. To test when cooked, insert paring knife dipped in center of custard. CUSTARDS 89 It will come out clean when custard is firm. Custard baked too fast or too long will be honey-combed and will break down. Beef-tea Custard. 1 cup of hot beef stock; yolks of 3 eggs; \ teaspoonful of salt; seasonings, if allowed, of parsley, spices, celery, etc. Prepare as for boiled custard; stir constantly until thick. Serve hot or cold. CHAPTER XIV. MILK. Water, Protein, Fat, Carbohydrate, Ash, Material. per cent. per cent. per cent, per cent, per cent.

The casein contains phosphate and lime. The carbohydrate of milk is in the form of lactose or milk sugar, and the fat is in a finely divided state, which rises to the top in the form of cream. Vitamins are present in milk, and these, as well as the protein constituents of the milk, are destroyed by high temperature. The conclusion is that fresh raw milk is preferable to pasteurized or ster- ilized milk. Food Value of Milk.—While milk contains all of the food principles, they are not present in correct proportions to sustain adult human life. Human milk is a perfect food for infants, but for adults the proportion of sugar is not high 1 U. S. Department of Agriculture, Farmers’ Bulletin, No. 363. Pasteurized milk 91 enough to give the proper amount of energy, and the propor- tion of water is so great that very large quantities of milk have to be taken in a day to furnish food for tissue-building and for energy production. Digestibility of Milk.—Milk forms a curd in the stomach as a result of the action of rennin in the gastric juice. If milk is taken in very rapidly the curd is heavy and dense. If it is taken in slowly and combined with other food, as cereal water, the curd is light and flocculent. Commercial rennet is obtained from the lining of the stomach of the calf, and is used to make desserts. Souring of Milk.—Milk sours because lactic acid bacteria which develop in it changes the sugar in the milk to lactic acid. This acid causes the casein to precipitate in the form of a curd. The liquid part contains sugar and salts and is known as whey. Certified Milk.—This is milk containing not more than 10,000 bacteria per cubic centimeter. Such milk can be produced only in model dairies. Pasteurized Milk.—Pasteurized milk is deficient in the anti- scorbutic vitamin, the absence of which in infant food tends to produce infantile scurvy. Consumers are protected, however, by pasteurization, since the process destroys bac- teria resulting in typhoid, scarlet fever, septic sore throat and bovine tuberculosis. Pasteurized milk is prepared by holding it at from 145° F. to 165° F. for thirty minutes and chilling it immediately. There will be less vitamin destruc- tion if it is kept at the lower temperature. The home method of pasteurization is as follows: 1. Sterilize bottles, fill them with milk and insert stoppers of baked cotton. If milk comes bottled, it may be left in the original container and a hole may be made in the cover through which to insert a milk thermometer. 92 MILK 2. Set the bottles on a rack in a large pan of cold water and heat until the contained milk is 145° F. Hold this temperature for thirty minutes. 3. Chill by putting pan under faucet and allowing cold water to gradually replace the hot. Place on ice immediately. Sterilized Milk.—In boiled milk there is a precipitation of the mineral salts; the casein is rendered less susceptible to the action of rennin and pepsin and a part of the albumin is precipitated. Sterilized milk is milk held at 212° F. for one and a half hours. This destroys bacteria of the Bacillus coli group, but it renders the milk very indigestible. The pediatrists believe that milk boiled for from two to ten min- utes is sufficiently protected for infant-feeding. This milk, however, cannot be said to be entirely sterile. Koumyss.—This is an imitation of fermented mares’ milk, used as a beverage in certain localities in Europe. Patients who cannot tolerate whole milk may be able to digest koumyss. Its casein is in an easily digestible form; the carbon dioxide gas it contains encourages the action of the stomach, and the alcohol formed is slightly stimulating. Koumyss. 1 quart of milk; \ yeast foam cake; 1 tablespoonful of lukewarm water; 2 tablespoonfuls of sugar. Add the sugar to the milk and the yeast, the latter having been dissolved in lukewarm water. Mix thoroughly. Pour into sterile bottles within two inches of the top. Cork securely in bottles having a patent top. Let them stand at the ordinary room temperature for six hours. Place on ice for twenty-four hours. Peptonized Milk.—This may be made by either one of the following methods: PEPTONIZED MILK 93 1. The immediate process in which the peptonizing powder is merely shaken into the milk and the milk then iced. 2. Partial Peptonization.—Take 1 tube of Fairchild’s pep- tonizing powder, \ cup of cold water and 2 cups of fresh cold milk. Shake the water and the powder together in a jar; add the milk and shake again. Set jar in warm water; keep temperature at 130° F. for twenty minutes. Put on ice at once. This may be served with any seasoning pre- scribed by the physician. 3. Completely Peptonized Milk.—Milk is completely pep- tonized by placing the mixture in No. 2 at a temperature of 120° F. maintained for two hours. This method is apt to develop a bitter taste. Malted Milk. 1 tablespoonful of Horlick’s malted milk; 2 tablespoonfuls of tepid water; salt. Make a paste with the above; add 1 cup of water, cold or hot, or of milk, to which cream may be added. Add the liquid gradually; stir briskly; serve prefer- ably hot. Junket. 1 cup of fresh milk; 1 teaspoonful of cold water; J junket tablet. Crush the junket tablet. Heat the milk until lukewarm. Add the junket, dissolved in cold water. Keep in a warm place until firm. Chill. Serve plain or with whipped cream, nutmeg or cinnamon. Lemon Whey. 1 pint of hot milk; 4 tablespoonfuls of lemon juice; 2 tea- spoonfuls of sugar. 94 MILK Add the lemon juice mixed with sugar to the milk. When milk has curdled, strain it through cheesecloth. Cottage Cheese. 1. 1 quart of sour milk; \ teaspoonful of salt; 2 table- spoonfuls of cream. Heat to the boiling point the sour milk. Remove from the fire and allow it to stand until the curd separates from the whey. Strain through a cheesecloth. Press until dry. Add the salt and cream and mix well. This makes one-half cup of cottage cheese. 2. 1 quart of sweet milk, 1 rennet tablet. Heat, to hike warm, the sweet milk. Remove from the fire. Dissolve rennet tablet in 1 tablespoonful of cold water and add to the warm milk. Allow the mixture to stand at room temperature until firm—about one hour. Strain through a cheesecloth. Press until dry. CHAPTER XV. STARCH-CEREALS-VEGETABLES. Cooking of Starch.—The covering of the starch granule is a delicate form of cellulose. Hot water and long cooking break down this covering and make the starch digestible. Each granule of starch must be held apart, as in an emulsion, by some material such as sugar, fat or cold water, to prevent a tendency to lumping when the starch is treated with heat and water. Examples of food preparations in which lump- ing is prevented by mixing starch with sugar is cornstarch pudding, water in the making of gravy, combining starch with a fluid fat as in a cream sauce. Blanc Mange. 1 quart of scalded milk; \ cup of cornstarch; \ cup of sugar; few grains of salt; 2 tablespoonfuls of cold water or milk; whites of 3 eggs (if desired). For chocolate blanc mange, melt 1 square of chocolate and add 4 tablespoonfuls of sugar to recipe. Mix starch, sugar and salt with water, stir into hot milk. Stir until the mixture thickens. Cover and let it steam for twenty minutes. If the whites of eggs are used, beat stiff and fold into the pudding after removing from fire; add flavoring; pour into mold; chill quickly. Cooking of Cereals.—Boil for ten minutes directly over the flame in a large quantity of water, already boiling and to which salt has been previously added. Stir until well mixed with a fork. Then put it in the top of a double boiler and 96 STARCH—CEREALS—VEGETABLES allow it to cook the required length of time. Fruit may be added to the cereal half an hour before removing it from the fire; as, for example, figs, dates, apples, prunes. Cooking of Vegetables. —1. Put vegetables in boiling water, using as small an amount as possible, excepting in the case of the more strongly-flavored vegetables. 2. Leave the skins on if possible while cooking. 3. Remove from the fire when tender and drain at once. 4. Keep covered while cooking to retain the flavor. 5. Add salt when half-cooked in order to keep vegetables tender. 6. Strongly-flavored vegetables should be cooked in a large amount of water and the water should be changed two to four times. Small pieces of bread, potato or char- coal tied in a cloth will absorb some of the flavor if placed in the water. 7. Water in which vegetables of not too strong flavor have been cooked should be saved and used in soup-making. It contains valuable principles. Boiled Potatoes. Select potatoes of uniform size, scrub and remove spots, put into boiling water, boil for twenty minutes, or until tender. Drain off the water, shake the pan over the fire to make the potatoes dry and mealy. Remove skins and serve in a hot uncovered dish. Mashed Potatoes. Mash boiled potatoes in a hot buttered dish; add season- ings and a little hot milk. Beat with a fork to make light and creamy. COOKING OF VEGETABLES 97 Scalloped Potatoes. Wash, pare and cut potatoes into thin slices; place in buttered baking dish; sprinkle with salt and pepper; dredge with flour and dot with small pieces of butter. Repeat these layers until the dish is almost full. Add hot milk until it may be seen through top layer. Bake one hour, or until potatoes are soft, in a moderate oven. Baked Potatoes. Select potatoes of uniform size; wash and scrub; prick to allow steam to escape. Bake in a hot oven forty-five to fifty minutes. When baked, break open slightly; serve on folded napkin. Aspakagus. Wash, cut into two-inch pieces. Cook in boiling salted water until tender; put in flower end of stalks when stalks are partly cooked, as they require less time for cooking. Drain off water, season, arrange on toast, pour over wdute sauce, if desired, or drawn butter. Carrots. Wash and scrub; cook entire and then cut into j-incb cubes. Cook in boiling water until soft, about one hour. Serve with white sauce. When possible, boil carrots whole; when cold cut into cubes and reheat in sauce. Put onions in cold water. Remove skins under water. Drain, put in boiling salted water; cook ten minutes. Drain, cover again with boiling water; do not cover dish while cooking. Boil until tender, drain; add small quantity of hot milk, butter and seasonings. Boiled Onions. 98 STARCH—CEREALS—VEGETABLES Carrot Mounds. Cut carrots, either before or after cooking, into small cubes of | inch. Drain carefully and season with salt and pepper. Stick pieces together with thick white sauce. Press mixture firmly into a well-buttered bowl; let it stand in hot oven five minutes. Invert on plate, garnish with parsley or small green peas. Surround with white sauce. Turnip Cups. Scoop out center from flat turnips which have been pared. Boil the whole; remove from water the minute they are done. Dry out over low flame; season; fill cavity with tiny cubes of turnip and carrots (and peas if at hand). Heat the filling first in a small amount of butter; also season highly and garnish with parsley. Serve, as individual dish, with white sauce. Spinach Balls Boil spinach until tender; drain, add to thick white sauce. Form into balls, serve with white sauce as a garnish or use hot mayonnaise in place of white sauce. Stuffed Onions. Boil until nearly tender; drain and cool. When they can be comfortably handled, remove centers, chop fine and mix with bread crumbs and any chopped meat, as ham, chicken or veal. Pack centers quite full; put a few buttered crumbs on top. Bake about twenty minutes, basting every five minutes. Serve as a garnish for roast pork, mutton or chops. COOKING OF VEGETABLES 99 Cabbage au Gratin. Cook cabbage; shred into buttered baking dish. Pour white sauce on and mix slightly. Add salt, red pepper and grated cheese if desired. Cover with buttered crumbs and bake twenty minutes. Stuffed Tomatoes. Wipe and remove thin slices from stem end of six medium- sized tomatoes. Take out seeds and pulp; sprinkle inside of tomatoes with salt and let them stand inverted for one hour. Cook for five minutes 2 tablespoonfuls of butter with | tablespoonful of chopped onion. Add \ cup of finely chopped cold chicken or veal, \ cup of stale bread crumbs and tomato pulp; season to taste. Cook five minutes; add one egg, slightly beaten. Cook one minute. Refill tomatoes with mixture. Place in a buttered pan; sprinkle with buttered cracker crumbs and bake twenty minutes in a hot oven. Stuffed Potatoes. Cut slices from the top of six medium-sized baked pota- toes. Scoop out inside; mash, add 2 tablespoonfuls of butter, salt, pepper and 3 tablespoonfuls of hot milk. Then add whites of 2 eggs, well beaten. Refill skins and bake for five to eight minutes in a very hot oven. Potatoes may be sprinkled with grated cheese before putting in the oven. Rice. Wash rice in cold water by scrubbing between the hands. Sprinkle the washed rice in six times its volume of boiling water; boil until rice is tender; drain, cover with cold water. Drain again and shake dry over fire or dry in the oven. This 100 STARCH—CEREALS—VEGETABLES may be served as a potato substitute or combined with eggs and fruit as a pudding. It is sometimes served as a dessert, in cereal bowls, with butter and maple syrup. Hollandaise Sauce. \ cup of butter; 2 egg yolks; 2 tablespoonfuls of lemon juice; \ teaspoonful salt; few grains cayenne pepper; § cup of boiling water. Put butter in bowl; cover with cold water; wash, using a wooden spoon. Divide in three pieces; put one piece in top of a double boiler with yolks of eggs and lemon juice; stir constantly until butter is melted; add second piece of butter, and, as it thickens, a third piece. Add water, cook five minutes and season. CHAPTER XVI. GELATIN. Food Value.—Gelatin is an incomplete protein. It lacks tyrosin and tryptophan, without which it cannot perform all the functions of a true protein. It is obtained by boiling collagen. While gelatin itself is lacking in full food value, it can be used as a vehicle to carry other foods. Effect of Water on Gelatin.—Gelatin does not dissolve, but softens and swells in cold water. It dissolves completely in hot water and thickens upon cooling. Boiling will destroy this thickening property. Tomato Jelly. cups of cooked tomato; 1 slice of onion; 1 stalk of celery; 1 bay leaf; 2 cloves; \ teaspoonful of salt; § cup of cold water; 1 piece of red pepper; f cup of mushroom par- ings; 1 tablespoonful of vinegar; 2 tablespoonfuls of gelatin.

Dissolve in boiling water; add sugar and lemon juice. Chill until quite thick and then beat to a froth. Add whites of eggs, beaten stiff, and con- tinue beating until stiff enough to hold its shape. Pile in sherbet cups and pour soft custard over it. Almond Cream. 1 cup of heavy cream; \ cup of hot milk; \ cup of cold milk; 2 teaspoonfuls of vanilla; 1 tablespoonful of gelatin; 1 pound of chopped almonds. Soak gelatin in cold milk, dissolve in hot milk; cool and add cream. Beat until stiff; add brown, blanched almonds and serve in cups lined with lady-fingers. CHAPTER XVII. DESSERTS. Food Value.—These preparations may be highly decorative and lend a gay touch to the tray that will appeal to the patient. Aside from this, they contribute an appreciable amount of food value. They are generally built on egg, cream or gelatin foundations and highly sweetened. It is fitting that they should come at the close of a meal, since they quickly impair the appetite. Tapioca Cream. \\ tablespoonfuls of minute tapioca; 2 cups of scalded milk; 2 eggs; | cup of sugar; \ teaspoonful of salt; \ teaspoon- ful of vanilla. Wash tapioca; add salt and milk and cook in a double boiler until the tapioca is transparent. Beat eggs and add sugar. Whip the hot mixture into the beaten egg.

Preparation of Fresh Fruits. Whenever possible serve fresh fruits in their natural state— that is, uncooked. Their flavor is much better, they are more appetizing and, in most cases, they are as digestible as cooked fruit. 1. Berries.—Wash all berries when they come from the market before removing stems or hulls. Serve cold with powdered sugar and cream. 2. Oranges.—Wipe fruit with a clean damp cloth. Serve in any of the following ways: (a) Remove the juice and strain into a cold glass. Add sugar if necessary. (b) Cut in halves; loosen pulp by cutting into sections. Remove seeds, sprinkle with powdered sugar, chill and serve. A spoonful of sherry may be added to grapefruit if desired. (c) Peel, remove all white skin, then break the fruit pulp APPLE SNOW 109 carefully into sections. Arrange in a circle around a mound of powdered sugar. The skin may also be removed from the sections before serving if desired. (d) Orange and grapefruit cocktail. Mix equal parts of diced orange and grapefruit pulp. Sprinkle with sugar; add a few drops of lemon juice. Serve in chilled glasses, garnished with a sprig of fresh mint or a Maraschino cherry. 3. Watermelon— Cut small balls from the ripest part of the melon with a vegetable cutter. Arrange in a mound on a fresh grape leaf, or pile in a sherbet glass and garnish with mint. 4. Apples.—Apples are seldom used raw in serving fruit to the sick. They may, however, be cooked in a number of digestible and appetizing ways: Baked Apples. Select as many good apples of uniform size as may be needed. Wash, pare and core them. Place them in a granite baking dish, fill the center of each apple with sugar, add a piece of butter on the top of each. Add enough water to cover the bottom of the pan. Bake in a hot oven until soft, basting often with the juice in the pan. Chill and serve plain, with whipped cream or with soft custard. Apple Snow. Pare, core and cut four apples into quarters. Cover with boiling water. Cook slowly until apples are very soft and water has almost evaporated. Cool, put through a vege- table sieve; add powdered sugar to taste and fold in half as much whipped cream as you have apple pulp. Chill and serve. 110 DESSERTS Apples, Cuban Style. Pare and core sound tart apples. Steam until almost tender; remove to a buttered baking dish; fill cavities with cocoanut; stick apples with blanched almonds; baste with syrup made of sugar and water and lemon juice. Finish cooking in a hot oven, basting often. Serve garnished with jelly or whipped cream. Banana Baked in the Skin. Open skin of banana on one side enough to loosen it entirely except at the end. Put it into a shallow pan; sprinkle with sugar and a little lemon juice. Bake until the skin is delicately browned and the pulp quite soft. Garnish with a spoonful of jelly and whipped cream. Baked Bananas. Remove the skin from a banana and scrape to remove coarse pulp. Melt 2 tablespoonfuls of butter in a granite baking pan; put in the banana, sprinkle with sugar and a few drops of lemon juice. Bake slowly, turning the banana once and basting during cooking. Serve cold. Senna Prunes. Prepare senna infusion by putting half an ounce of senna leaves into a pan provided with a cover. Pour over the leaves 1 quart of boiling water and allow it to stand for half an hour. Strain and pass enough water through the strainer to make the infusion measure 1 quart. Soak 1 pound of prunes in this infusion overnight. Cook prunes until soft, adding enough water to have 1 quart of juice when the cook- ing is over. Patients may be given this in decreasing doses, beginning with 6 prunes and 6 teaspoonfuls of juice, for breakfast and supper, and gradually cutting it as the need for a laxative lessens. CHAPTER XVIII. FROZEN DESSERTS. Patients are very grateful for frozen preparations. They are a means of pushing the use of fluids, adding fruit juices to the diet and give an opportunity of selection. They contribute variety for the patient on liquid diet. Frozen desserts include: 1. Ices: fruit juices sweetened, diluted with water and frozen. 2. Sherbets: fruit juices sweetened; diluted with water and combined with beaten whites of eggs. Milk may be used in place of water. 3. Frappe: ices frozen coarsely to a granular consistency; equal parts of salt and ice are used and the freezer turned rapidly. 4. Philadelphia cream: cream sweetened, flavored and frozen. 5. Custard ice-creams: custard foundation combined with cream and flavoring. 6. Parfait, whipping cream, beaten until stiff; combined with egg white into which has been beaten the hot syrup, flavored, placed in a mold, packed in salt and ice (using 2 parts of ice to 1 of salt) and allow to stand three hours. In freezing creams, ices, etc., use 3 parts of ice to 1 of salt. Lemon Ice. 4 cups of water; f cup of lemon juice; 2 cups of sugar. Make a syrup by boiling the water and sugar for twenty- minutes. Add lemon juice, cool, strain and freeze. 112 FROZEN DESSERTS Orange Ice. 4 cups of water; 2 cups of orange juice; 2 cups of sugar; \ cup of lemon juice; grated rind of 2 oranges. Make a syrup as for lemon ice; add fruit juice and orange rind; strain and freeze. White Velvet Sherbet. The juice of 4 lemons; the thinly shaved peel of 1 lemon is soaked in the juice for half an hour. Strain the juice and add enough sugar to thicken mixture; add 1 quart of milk and turn at once into the freezer. Turn slowly at first and rapidly as it thickens. Raspberry Ice. 1 quart of raspberries; 1 cup of water; 1 cup of sugar; | cup of lemon juice. Sprinkle the raspberries with sugar; cover and let them stand for two hours. Mash, sqeeze through sieve, add water and lemon juice to taste; then freeze. Raspberry ice pre- pared in this way retains the natural color of the fruit. Strawberry Ice. Prepare the same as raspberry ice. Pineapple Frappe. 2 cups of water; 2 cups of ice water; 1 cup of sugar; 1 pint of grated pineapple; juice of 3 lemons. Make a syrup of the water and sugar, boiling it for fifteen minutes. Add the pineapple and lemon juice; cool; strain, and add ice water; freeze to a mush, using equal parts of ice and salt. CHOCOLA TE ICE-CREA M 113 Grape Frappe. 4 cups of water; 2 cups of grape juice; \ cup of lemon juice; 2 cups of sugar; f cup of orange juice. Prepare and freeze as for pineapple frappe. Philadelphia Ice-cream. 1 quart of cream; f cup of sugar; | teaspoonful of vanilla. Mix ingredients and freeze. Cranberry Frappe. 1 quart of cranberries; 2 cups of sugar; 2 cups of water; juice of 2 lemons. Cook cranberries in water for eight minutes, then force through a sieve. Add sugar and lemon juice and freeze to a mush. This may be served with a meat course of dinner in place of sauce or jelly. Vanilla Ice-cream. 2 cups of scalded milk; 1 cup of sugar; § teaspoonful of salt; 1 tablespoonful of flour; 1 egg; 1 quart of cream. Mix flour, sugar and salt; add egg slightly beaten and milk gradually. Cook in the top of a double boiler for twenty minutes, stirring constantly. When cool, add cream and flavoring; strain and freeze. Chocolate Ice-cream. Use recipe for vanilla ice-cream. Melt 2 squares of choco- late; add hot custard slowly; cool and add cream. 114 FROZEN DESSERTS Caramel Ice-cream. 1 quart of cream; 1 cups of sugar; 1 tablespoonful of flour; \ teaspoonful of vanilla; 2 cups of milk; 1 egg; | teaspoonful of salt. Prepare the same as for vanilla ice-cream, using only \ of the sugar. Caramelize remaining sugar and add slowly to hot custard. Freeze. Angel Parfait. 1 cup of sugar; whites of 3 eggs; f cup of water; 1 pint of heavy cream; 1 tablespoonful of vanilla. Make syrup of sugar and water, boiling to thread. Pour slowly on beaten whites; continue beating until mixture is cool. Add cream, beaten stiff; add vanilla; freeze. Maple Parfait. 4 eggs; 1 pint of thick cream; 1 cup of hot maple syrup. Beat eggs slightly; pour on maple syrup slowly. Cook until mixture thickens; cool, add cream, beaten until stiff. Mold, pack in salt and ice and let it stand for three hours. Rose Petal Mousse. 1 cup of sugar; whites of 3 eggs; 1 teaspoonful of rose extract; \ cup of water; fragments of rose petals from Groses. Boil the sugar and water until a thread will form. Add the rose petals; cool, beat into well-beaten whites of eggs. Flavor. When stiff, pour into mold. Pack mold in 3 parts of ice to 1 part of salt. Let it stand three hours. CHAPTER XIX. SALADS. Composition.—A salad formerly meant a green, crisp vege- table, dressed with oil, vinegar, salt and pepper. The term has now been changed to include cooked vegetables, fish, meat, eggs or fruit, served alone or in varying combination. Food Value.—Salads are extremely valuable as giving variety to the diet, especially when they are planned with proper relation to the rest of the meal. It can readily be seen that their cost is not great. The green salad plants— celery, endive, cress, cucumber, lettuce, onions romaine, with radishes and tomatoes—furnish the food basis. The salads also provide mineral salts and vitamins and furnish suitable roughage. All forms of salad dressing are high in food value, because of the easily assimilated fats which they contain in the form of cream, butter, olive oil, eggs, etc. Meat and fish salads contain a great deal of food value and should only be used as the principal dish of a meal. They are too heavy to serve as an additional course at dinner. Essential Points to be Observed in Making Salads. — 1. All materials for salads should be cold. 2. Greens should be fresh, crisp and thoroughly washed in cold water. 3. The combination of materials must be suitable and have some relation to the other parts of the meal. 4. Materials must be neatly cut, arranged and garnished. 5. The materials in the dressing must be well blended. The dressing should be neither too strong of oil nor of acid. 6. The salad materials and the dressing must be well mixed just before serving. 116 SALADS Classes of Salad Dressing. —1. French dressing, a combina- tion of oil, vinegar or lemon juice and seasonings uncooked. Suitable to serve with vegetables and fruits. 2. Cream dressing, a cooked dressing made of milk or cream, vinegar and seasonings. Suitable to serve with any kind of salad. 3. Mayonnaise, an uncooked dressing made of oil and yolks of eggs for a foundation and seasonings and acid added as desired. Best for use with meat and fish salads, although it may be used with any combination. To Serve with Salads.—Crisp toasted crackers; crisp toasted cheese crackers; cheese straws; cheese balls; small sandwiches of white, rye, brown or nut bread. SALADS AND SALAD DRESSINGS. French Dressing. \ teaspoonful of salt; 2 tablespoonfuls of vinegar; 4 table- spoonfuls of olive oil; \ teaspoonful of pepper or cayenne to taste. Blend the ingredients by beating with a silver fork in a salad bowl, or shake together in a bottle when dressing is not prepared at the table. Other seasonings may be added as desired. Almond Salad Dressing. 4 egg yolks, beaten stiff; 4 egg whites, beaten light; 1 cup of powdered sugar; \ teaspoonful of salt; juice of 2 lemons; \ cup of whipped cream. Separate eggs; beat, add sugar and continue beating; add salt and lemon juice. Cook in a double boiler until thick. SALADS AND SALAD DRESSINGS 117 Chill and add whipped cream and | teaspoonful of almond flavoring just before serving. This is to be served on fruit salads. Boiled Dressing. 1 teaspoonful of mustard; 1 teaspoonful of salt; 2 tea- spoonfuls of flour; | cup of milk; \\ teaspoonfuls of sugar; 1 teaspoonful of melted butter; 1 egg; § cup of hot vinegar. Mix dry ingredients; add butter, egg and vinegar slowly. Cook in a double boiler until the mixture begins to thicken. Add milk and cook until thick. Add butter last. Beat with a Dover beater to prevent curdling. Mayonnaise Dressing. 1 egg yolk; 2 tablespoonfuls of lemon juice or vinegar; few grains of cayenne; 1 pint of olive oil; f teaspoonful of salt. Beat egg yolks with silver fork on a plate; add salt and a few drops of lemon juice or vinegar. Add oil gradually, drop by drop, at first and stir constantly. As the mixture thickens, thin with lemon juice or vinegar. Add oil and acid alternately until all is used, stirring constantly. Ingredients must be well chilled and the dressing made in a cool place or the salad plate placed over a bowl of cracked ice. Fruit Salad. 1 can pineapple; 1 large stem malaga grapes; \ cup of walnuts; 1 orange; 1| cups of white cherries. Pile fruit lightly in lettuce cup. Swiss Salad. 1 cup of cold chicken in cubes; 1 cup of cucumber cubes; 1 cup of English walnuts; 1 cup of French peas. 118 SALADS Marinate with French dressing. Serve with mayonnaise in crisp lettuce leaves. Cress Salad. Mix water-cress with an equal quantity of chopped celery and serve with French dressing or mayonnaise. Vegetable Salad. Mix crisp lettuce or endive with sliced tomatoes, cucumbers green peppers and celery cut finely. French dressing may be used. CHAPTER XX. FLOUR MIXTURES. Digestibility.—Twice-cooked breads, as zwieback or toast, are dextrinized and therefore more available forms of food than fresh bread. However, there are occasions when the digestion is not impaired and some of the following recipes may be used: Toast.—Toast should be served as hot as possible. It is rendered less digestible by buttering before it is served. The fat penetrates the food material, and having been melted and cooled, will probably solidify again before being eaten. Both bread and butter thus become more difficult of digestion. Flour Mixtures.—Flour mixtures are combinations of flour with some liquid. Some kind of a leavening agent is always added, and usually one or more of the following materials: sugar, shortening, egg, fruit or nuts. These last named materials are added to make the mixture richer or to give it flavor. Flour mixtures are divided into the following classes, depending upon the proportions of flour and liquid used: Batter.— 1. Pour-batter contains 1 measure of flour to 1 measure of liquid. Examples: popovers. 2. Drop-batter contains about 2 measures of flour to 1 of liquid. Example: muffins. Dough.— 1. Soft dough contains about 2§ measures of flour to 1 measure of liquid. Example: baking powder biscuits. 2. Stiff dough contains 3 or more measures of flour to 1 of liquid. Example: bread. Leavening Agents.—There are three classes of leavening agents: 120 FLOUR MIXTURES 1. Air: introduced into flour mixtures by beating or by beating eggs and adding them to the mixture to be beaten. 2. Steam: heat of the oven changes the liquid in the mix- ture to steam. This expands and makes the mixture light, although the expansion is limited by the crust which forms on the outside. 3. Carbon-dioxide gas: this is produced by: (а) The use of soda with an acid, as in sour milk or cream of tartar. Baking powder contains 1 part of soda to 2 parts of cream of tartar and a little cornstarch to take up moisture and keep the powder dry. (б) Yeast. Flour.—There are two kinds of white flour: that made from spring wheat, and called bread flour, and that made from winter wheat, and called pastry or cake flour. The former is rich in gluten, which gives it elasticity and makes it the best for bread-making. The latter contains a higher percentage of starch, so that it is lighter and more suitable for cakes and pastry. Besides the white flours there are coarse flours, their quality depending upon the process of milling and the number of bran coats not removed. Graham and entire wheat flour are richer in protein and ash constituents than any of the white flours. While authorities differ upon the relative food value of coarse and fine flours, it is certain that dark flours, because of their larger bulk, are a very valuable addition to the diet of people of sedentary habits. Oven Tests.—1. Heat may be tested by an oven ther- mometer. 2. Heat may be tested by placing a hand in the oven and counting eight for very hot, ten for hot, twelve for moderate and sixteen for slow, referring to the limit of heat endurance. TO TEST COMPLETE BAKING 121 3. A very hot oven is one in which a piece of white paper turns brown in three minutes. All small hot breads require a hot oven. Large cakes and breads require a moderate oven. To Test Complete Baking. —1. The material shrinks from the side of the pan. 2. No depression is left after pressure with the finger. Baking Powder Biscuits. 1 cup of flour; \ teaspoonful of salt; \ cup of milk or water; 2 teaspoonfuls of baking powder; 1 tablespoonful of butter. Sift the dry ingredients; chop the butter in with two knives; add the liquid gradually; put the dough on lightly floured board; pat gently into round cake; roll out, keeping dough as soft as possible, to 1 inch of thickness. Cut with biscuit cutter; put on shallow tin. Bake for about thirty minutes. Popovers. 1 cup of flour; 2 eggs; 1 cup of milk; | teaspoonful of salt. Beat eggs very light; add milk and the sifted dry ingre- dients, beating constantly. Bake in hot well-greased gem pans in a hot oven for fifteen to twenty minutes. Shortcake. 2 cups of flour; 1 teaspoonful of salt; 2 tablespoonfuls of butter; 4 teaspoonfuls of baking powder; | cup of sugar; f cup of milk; 1 quart of berries. Sift the dry ingredients. Cut in the butter. Add fluid. Bake for thirty minutes. 122 FLOUR MIXTURES Nut Bread. 1 egg; | teaspoonful of salt; 4 teaspoonfuls of baking powder; 1 cup of nuts; \ cup of sugar; 1 cup of milk; 3 cups of flour. Cream the egg and sugar. Add the milk; add flour sifted with dry ingredients and bake in a moderate oven for forty- five minutes. This recipe may be made salt-free for one on a salt-free diet. Health Bread. 2 eggs; \ cup of molasses; | cup of sugar; 1 cup of cornmeal; 2 teaspoonfuls of baking powder in flour; \ cup of walnuts; 2 cups of milk; \ teaspoonful of soda in molasses; 1§ cups of bran; 3| cups of white flour; \ cup of raisins or figs. Beat the eggs and add other ingredients; mix well. Bake in two loaves in moderate oven for forty-five to sixty minutes. Bran Muffins. \\ cups of bran; f teaspoonful of soda; 3 eggs; 1| tea- spoonfuls of salt; 1| cups of buttermilk. Bake in one dozen muffin tins; press down well in tins and bake in moderate oven for thirty minutes. Bran Bread. 4 cups of sour milk; 1 cup of molasses; 3 teaspooufuls of salt; 3 level teaspooufuls of soda; | cup of sugar (or more). Mix above thoroughly. 3 cups of bran; 3 teaspoonfuls of baking powder; 5 cups of graham or wheat flour. Mix and add to the first mixture. Add raisins, figs, dates, nuts, etc., as desired. This should make three loaves. Bake slowly with, at first, a hot oven, from forty-five to sixty minutes. CHAPTER XXI. CAKE. Classification.—Cakes are of two kinds: 1. Cakes made on an egg foundation. These alone are used in invalid cookery. They include sponge cake, sunshine cake, angel cake and lady-fingers. 2. Cakes containing butter or some other fat. Examples are cup cake and pound cake. Success in cake-making is conditioned upon the following precautions: 1. L se only the best materials and pastry flour, if possible. 2. Measure accurately. 3. Have a uniform heat for baking: a slow oven for sponge cakes; a moderate oven for loaf cakes and a quick oven for cup cakes and layer cakes. 4. Grease tins thoroughly for butter cakes; do not grease tins for sponge cakes; and keep separate tins for sponge cakes, if possible. 5. Be careful to watch the cakes during baking. How to Tell When a Cake is Cooked.—1. Insert a tooth- pick or knitting needle; if it comes out clean and dry, the cake is done. 2. Press the cake gently with your finger; if it springs back into place and does not leave a dent it is done. 3. When the cake shrinks from the side of the pan it is done. The Four Stages of Cake-baking. —1. In first quarter of baking the cake begins to rise. 2. In second quarter of baking the cake continues to rise and begins to brown. 124 CAKE 3. In third quarter of baking the cake continues to brown. 4. In fourth quarter of baking the cake shrinks from pan. The Care of Cake after Baking. —1. Remove it at once from the pan to a board or table, covered with a clean cloth. 2. If the cake sticks to the pan, invert it and cover the bottom with a damp cloth. The cake will steam out. 3. Let cake cool thoroughly before putting on frosting. In invalid cookery only sponge cakes are used. Flour.—Pastry flour is recommended in cake-making. If it cannot be secured, substitute 2 tablespoonfuls of corn- starch for 2 tablespoonfuls of flour in each cup of flour called for in the recipe. Sponge Cake. 6 eggs; 1 cup of sugar; 1 tablespoonful of lemon juice; 1 tablespoonful of orange juice; f teaspoonful of salt; grated rind of | lemon; 1 cup of flour. Beat the eggs until thick and lemon colored; add sugar and continue beating. Use a Dover beater. Add lemon rind and fruit juice. Cut and fold in flour mixed and sifted with salt. Bake forty-five minutes in a slow oven. Remove from pan immediately the cake is baked. Hot Water Sponge Cake. Yolks of 2 eggs; 1 cup of sugar; f cup of hot milk or water; j teaspoonful of lemon extract; whites of 2 eggs; 1 cup of flour; teaspoonfuls of baking powder; | teaspoonful of salt. Sift the sugar. Beat the yolks until thick and lemon colored. Add half of the sugar gradually; continue beating. Then add water, the remaining sugar, lemon extract, whites of eggs beaten until stifl, and flour, mixed and sifted four SUNSHINE CAKE 125 times, with baking powder and salt. Bake for twenty-five minutes in moderate oven, in a buttered and floured shallow pan. Lady-fingers. 4 eggs; | cup of powdered sugar; 1 cup of flour; 1 teaspoon- ful of vanilla. Mix as for any sponge cake and press through a tube on a baking sheet covered with two thicknesses of paper. Make cakes 5" x l" in size. Dust with powdered sugar. Bake for ten to fifteen minutes, in a moderate oven, without browning. When cool remove from paper and brush over the flat sur- face with slightly beaten white of egg and put together. Angel Food. 1 cup of whites of eggs (about 10); 1 cup of fine granulated or fine powdered sugar; 1 cup of flour; teaspoonful of cream of tartar; 1 teaspoonful of flavoring. Sift the flour six times. Also sift the sugar six times. Beat whites until foamy. Sprinkle in cream of tartar and beat until dry. At this stage beat in of the sugar then fold in the rest. The beating should be continued until the mixture is stiff, but still retains its foarmy character. Then sprinkle flavoring over it and fold in flour. Bake in new unbuttered tin. Put in a hot oven, then decrease heat. Bake for thirty to fifty minutes. Sunshine Cake. Whites of 7 eggs; yolks of 5 eggs; 1 cup of sugar (granu- lated or powdered); § cup of flour; 1 teaspoonful of orange extract or 2 teaspoonfuls of orange juice; a few drops of lemon juice; f teaspoonful of cream of tartar. 126 CAKE Sift the sugar four times. Also sift the flour four times. Beat the yolks until thick and creamy. Beat the whites until foamy and add the cream of tartar and beat until dry. Meanwhile sprinkle half of the sugar into the whites, beating but not losing the puffy appearance. Fold in the rest of the sugar; slowly pour the yolks on the whites and mix by folding. Add flavoring. Fold in flour. Bake in an unbuttered pan for thirty-five to fifty minutes. Nut Wafers. 2 eggs; 1 cup of brown sugar; 1 cup of walnuts, chopped; | cup of flour; £ teaspoonful of salt. Beat the eggs, add the sugar and then the flour. Mix well and drop on inverted tins (buttered) from tip of tea- spoon. Bake in a quick oven for ten minutes. Fruit Cookies. 1 cup of sugar; 2 eggs; \ teaspoonful of soda; § cup of sweet milk; 1 teaspoonful of cloves; 1 teaspoonful of cinnamon; 1| cups of flour; 1 cup of raisins; | cup of butter.

Whites of 2 eggs; 1 tablespoonful of cornstarch; 1 cup of confectioners’ sugar; 1 tablespoonful of cream of tartar; 2 cups of cocoanut. Beat the eggs very stiff. Sift the sugar, cornstarch and cream of tartar in gradually, beating all the time. Stir in the cocoanut. Drop on buttered tins. Bake for fifteen .minutes in a very hot oven. WHITE FROSTING 127 Marshmallow Frosting. \ pound marshmallows; 1 cup of sugar; white of 1 egg; \ cup of water. Stand the marshmallows in the oven until theyrun together. Beat slowly into the egg. Make a syrup and add to the paste. White Frosting. White of 1 egg; 1 eup of sugar; 4 tablespoonfuls of cold water. Put all together in a double boiler and boil seven minutes; stir constantly and continue to stir after removing from fire until it begins to thicken, and then spread. CHAPTER XXII. MEAT Definition.—Meat is the flesh of animals used for food. The term is usually understood to include poultry and game. Physical Structure.—All meats have practically the same physical structure; that is, bone, cartilage, skin, connective tissue, muscular tissue, fat and juices. Different kinds of meat and different cuts from the same animal differ only in the arrangement of these physical parts. For example, the muscle fibers of beef and mutton are long and loosely con- nected, while those of pork and veal are short and compact. Protein Constituents of Meat.—These nitrogenous com- pounds may be classified as: Albumins and myosin, making up the lean part or flesh of the meat; collagen of connective tissue; and the ossein of bone, which yields gelatin. Nitrogenous extractives: a group of compounds which are soluble in water. These include urea and creatin, and are the chief ingredients in beef tea. Explanation of Fig. 2.

Except in such fat meats as pork or bacon, the protein content of meat averages 20 per cent. Mineral Content of Meat.—Meat is rich in phosphorus and iron, calcium, sulphur and sodium. Food Value.—Meat is economically the most important of the protein foods. The food value of meat depends upon the following points: 1. The kind of meat: chicken, for instance, is more easily digested than beef, because of its structure. 2. The cut of meat: the tender cuts from those portions of the animal little used are more digestible than the coarser cuts. 3. The care and feeding of the animal: underfed animals are poorly nourished and their meat lacks in nutritive value. 4. The method of cooking: tender cuts are cooked in dry heat to retain the juices; coarser cuts in moist heat to break down the connective tissue. Tests for Good Meat.—The lean part of good meat is firm, elastic, bright red and moist when exposed to the air. The tender cuts are fine-grained and finely marbled with fat. The fat is firm and of light straw-color, excepting around the kidney, where it is white and crumbly. Flabby, dark or coarse-grained meat with deep yellow fat indicates an old, underfed animal. Care of Meat in the Home.—1. Remove meat at once from the paper container to a clean platter or board. Paper absorbs the meat juices. 2. Keep it in a cool place until ready for use. 3. Wipe the meat with a clean cloth wrung out in cold water before cooking. Methods of Cooking Meat.—Meats are cooked in the follow- ing ways, depending upon the object to be attained. SCRAPED BEEF 131 1. To retain the juices, use tender cuts, as in broiling, baking and roasting. 2. To extract some of the juices and retain some, use the less tender cuts. Example: The rump. 3. To extract the juices, use the tough cuts or shank, as in the making of soups, broth or beef tea. Beef Juice. Select a piece of meat from the rump or upper part of the round. Cut into cubes about 2 inches square. Broil or warm slightly for one or two minutes, to set free the juices; then squeeze out juices by means of a press or lemon squeezer or potato ricer into a slightly warmed cup. Salt if neces- sary and serve at once. Serve in dainty china cups or in colored glasses to disguise the color of the juice. Beef Essence. Put half a pound of round steak, freed from fat, etc., through a meat grinder; put it into a glass fruit jar with one tablespoonful of cold water. Place the jar in a kettle of cold water. Heat gradually and keep at temperature of 150° F. for two hours. Strain and press the meat to obtain juice. Season with salt and serve immediately, or place on ice, where it will remain fresh for at least twelve hours. Note.—A small piece of raw beef, broiled slightly and then cut up and added to the above, improves the flavor. Scraped Beef. Cut a strip of sirloin or round steak half an inch wide. Lay it on a meat board and with a sharp knife scrape off the soft part until there is nothing left but the tough fiber. Sea- 132 MEAT son this pulp with salt and pepper. This may be used for making sandwiches or may be shaped into tiny balls or small flat cakes and pan-broiled with fat for two minutes, merely running a piece of suet over the pan to prevent the cakes from sticking. Beef Broth. 2 pounds of lean beef; 1 quart of cold water; teaspoonful of salt; pepper to taste. Wipe the meat, remove the skin and fat and cut the meat into small pieces. Put into a kettle with bones, add cold water and let it stand for two hours. Heat gradually to the boiling point and let it simmer for two to four hours. Do not allow it to boil. Season about half an hour before removing from the fire. Remove the fat by skimming through a cloth wet in cold water, or, better, by cooling the broth and letting the fat rise to the top, when it is easily removed. Roast Beef. Put the roast in a hot roasting pan. After the outside has been seared (ten minutes), season with salt and pepper. Baste about every fifteen minutes, cooking it for fifteen minutes to each pound. Cook a small roast rare. Broiled Steak. Wipe off and trim off superfluous fat. Heat the broiler very hot; rub it with a bit of fat and put in the steak. Have the broiler elose to the fire at first; turn twice in the first few minutes; remove to a greater distance from the fire; turn about six times. Eight to ten minutes are required to cook a rare steak. Garnish with slices of lemon, watercress or parsley. Maitre d'hotel butter may be spread upon steak. Sprinkle with salt when fully cooked. PAN-BROILED BACON 133 Maitre d’Hotel Butter. j cup of butter; \ teaspoonful of salt; § teaspoonful of pepper; \ tablespoonful of finely chopped parsley; f table- spoonful of lemon juice. Put the butter in a bowl and with a small wooden spoon work until creamy. Add salt, pepper and parsle}'-, and then lemon juice very slowly. Chops. Wipe and trim off superfluous fat. The small flank ends of loin chops may be cut off for the soup kettle or skewered around the rest of the chop. Bones of rib chops should be trimmed to uniform length; then scraped clean down to the eye of the meat. Cover bone with paper frill before serving. Mutton chops may be broiled the same length of time as for a rare steak. Lamb chops should be well done. Broil ten minutes for ordinary chop. Broiled Bacon. Place thin slices of bacon (from which rind has been removed) closely together in a fine wTire broiler; place broiler over a dripping-pan and bake in a hot oven until bacon is crisp and brown, turning once. Drain on brown paper. Pan-broiled Bacon. Place thin slices of bacon in a sauteing pan. Cook until crisp and brown, occasionally pouring off fat, and turning bacon frequently. Drain on brown paper. CHAPTER XXIII. FISH. Fish ranks next in value to meat among the protein foods. It is usually easier of digestion and contains fewer extrac- tives. This renders it a better food than meat for people taking little exercise. It has a high content of gelatin, which is lost if the fish is boiled. Therefore, it is better to cook it by means of dry heat. Selection.—Its freshness is the most important quality to be considered. The following points indicate freshness: firmness of flesh; brightness of eye; redness of gills; absence of unpleasant odor. To Prepare Fish for Cooking. —1. Even if cleaned well at the market, it should be wiped off thoroughly, both inside and out. 2. If the fish has not been scaled, scales are to be removed by working a knife over the fish, beginning at the tail and scaling toward the head. 3. If the fish is to be cooked whole the head and tail may be left on. 4. To remove the skin from a fish, slit the skin along the entire length of the backbone. Remove the fins. Then loosen the skin carefully with a small knife, working from the backbone, around one side at a time. 5. To remove the bones from a fish: after the skin is removed, begin at the tail and separate the flesh from the backbone on each side. Follow the ribs and work carefully toward the head. The entire backbone and ribs will come out together. METHODS OF COOKING 135 Methods of Cooking.—Broiling and baking are the most desirable methods of cooking fish. Large fish may be planked or stuffed whole. Small fish are best broiled or sauted. Clean a 4-pound haddock; sprinkle with salt inside and out; stuff and sew. Cut diagonal gashes on each side of the backbone and insert narrow strips of fat salt pork or bacon. Shape with skewers in the form of a letter S. Place on greased fish-sheet or on strips of cotton cloth in a dripping pan; sprinkle with salt and pepper. Bake for about one hour in hot oven, basting every ten minutes. Serve with drawn butter, egg, or Hollandaise sauce. Baked Haddock with Stuffing. Fisii Stuffing. \ cup of cracker crumbs; cup of stale bread crumbs; \ teaspoonful of salt; few drops onion juice; \ cup of melted butter; \ cup of hot water; | teaspoonful of pepper. Mix in order given. Clean the fish and cut in a long or short fillet. A fillet is a piece of fish freed from skin and bones. Roll if long and fasten with small wooden skewers or toothpicks. Sprinkle the fillet with salt and pepper; dip in egg and bread crumbs; saute and drain on brown paper. Serve with sauce tartar. Fried Fillet of Halibut. Pigs in Blankets. Season large oysters with salt and pepper; roll each tightly in a slice of bacon; fasten with toothpicks. Saute in hot omelet pan until the bacon is clear. Serve on triangles of toast with sauce, brown or tomato. 136 FISH Planked White Fish. Shad or white fish are the two common fish planked. Clean and split a 3-pound shad; put skin side down on a plank one inch thick and a little wider than the fish. Sprinkle with salt and pepper; brush with butter. Bake twenty-five minutes in a hot oven. Remove from the oven, spread with parsley and lemon and serve fish on plank. Blanked shad can be cooked in a gas range, having the flame over fish, or, in other words, broiled. Planked white fish of the Great Lakes has a high reputation. Garnishes. Lemon, parsley, tomato, tart sauces, hard-cooked eggs, cubed vegetables, water-cress, capers, nasturtiums, toast, shredded lettuce, potato roses, potato riced, potato balls and radishes. Horseradish Sauce. 4 tablespoonfuls of horseradish; 1 teaspoonful of powdered sugar; § teaspoonful of salt; | cup of hot cream or white sauce; 4 tablespoonfuls of bread crumbs; 2 tablespoonfuls of vinegar; \ teaspoonful of mustard (smoothed in water). Mix all the ingredients excepting the cream or white sauce. Cook in the top of a double boiler for five minutes. Just before serving add the cream or the white sauce. Tartar Sauce. 1 teaspoonful of lemon juice; 1 tablespoonful of Worcester- shire sauce; 2 tablespoonfuls of butter; j teaspoonful of salt; 1 tablespoonful of vinegar. Heat these all together in a bowl over hot water. Brown some butter in a frying pan and strain it into the mixture. CHAPTER XXIV. POULTRY. Poultry is the name given to all domestic birds used for food. This term includes: chicken, fowl, turkey, duck and goose. Chicken is the only one used to any extent in the diet of the sick. Selection.—Poultry one year old, or younger, is called chicken; over one year, fowl. Chickens weighing about one and one-half pounds are broilers. Young chickens have a smooth skin, soft feet, a large number of pin feathers, and the breast bone cartilage is soft and flexible. Fowl have scaly feet, long hairs, rigid breast bones and much fat around the internal organs. Digestibility.—The muscle fiber or flesh of poultry con- tains little fat. The fibers are also shorter than the fibers of mutton and beef. This makes them tender and easily digested. The white meat of chicken contains less fat and less connective tissue than the dark meat, and so it is more easily digested. Preparation. —1. Poultry should be dressed as soon as killed; the feathers come off more easily at that time. 2. The pin feathers may be removed with a sharp knife. 3. Singe the hairs, if any, by holding over a burning paper. 4. Cut off the head and feet. 5. Turn down the skin of the neck and cut off the neck close to the body; remove the crop and windpipe from the end of the neck. 6. Remove the tendons in the legs, one at a time, being careful not to tear the flesh. 138 POULTRY 7. Remove the oil bag from the tail. 8. Remove the internal organs carefully, being careful not to break the gall-bladder, which is attached to the liver and must be cut away without breaking. The lungs and kidneys lie in the hollow of the backbone and must be removed. Save the liver, the gizzard and the heart; these are called giblets, and are used in making dressing or gravy. Throw everything else away. 9. When everything has been removed, wash the bird carefully inside and out and wipe dry with a clean cloth. To Prepare Giblets for Cooking. —1. Press the heart to extract the blood and cut it open. 2. Remove the gall-bladder carefully from the liver. 3. Cut through the thick muscles of the gizzard and peel them off slowly without breaking through the inside lining. 4. Put them into cold salted water until ready for use. 5. When ready to cook, put the heart and the gizzard into cold water; heat quickly and cook at the simmering point until almost tender. Add the liver and cook until the giblets are tender. The liver does not require long cooking. To Truss a Fowl. —1. Draw the legs close to the body and either skewer them to or tie them to the tail. 2. Put another skewer through the wings and breast. To Cut a Fowl for Frying or Stewing. —1. Cut off the legs. Separate them at the joint between the drumstick and the second joint. 2. Cut off the wings and remove the tip of each. 3. Separate the wishbone with the meat on it from the breast. 4. Cut through the ribs on each side and separate the breast from the back. Cut through the breast in the center lengthwise and then the back through the center crosswise. 5. There should be 12 pieces. BROILED CHICKEN 139 Roast Chicken. Put a 4-pound bird on the rack in a roaster, ltub its surface with salt and spread upon the breast and legs 3 table- spoonfuls of butter creamed with 2 tablespoonfuls of flour. Roast in a hot oven, basting every ten minutes, until done. Use 2 tablespoonfuls of butter, melted in \ cup of hot water, for basting until enough fat comes out into the pan. Turn the chicken frequently so that it will brown evenly on all sides. When the breast meat is tender the chicken is done. This takes about one and one-half hours. Stuffing. 2 cups of bread crumbs; 2 tablespoonfuls of parsley (cut fine); 2 tablespoonfuls of celery (cut fine); 1 tablespoonful of onion (cut fine); | cup of hot water; 2 tablespoonfuls of melted butter; \ teaspoonful of salt; | teaspoonful of pepper; 1 egg. Add seasonings to the bread crumbs. Then add the melted butter, hot water and egg, well-beaten. Oyster Dressing. Add 1 pint chopped oysters, cleaned and drained, to above recipe. Broiled Chicken. Chicken for broiling should not weigh over 1| pounds. Split the broiler down the back. Break the joints; remove breast bone; clean and wipe well with a dry cloth. Season with salt and pepper and rub well with creamed butter. Put into hot broiler and broil for twenty minutes. Garnish with parsley and slices of lemon. 140 POULTRY Squabs. Singe the birds and make an incision, the length of the bird, down the backbone. Remove the contents and cut out small rib bones; cut through tendons at joints. Wash well and season. Spread the birds flat open on wire broiler and broil for ten minutes, turning four times. Garnish with parsley. Mock Fried. Use a spring chicken or capon. Parboil or steam until tender, then season; roll in flour or bread crumbs and saute until tender. Chicken a la Maryland. Cut in pieces; dust with salt, pepper and flour and sprinkle with lemon juice. Sprinkle with sliced onion, broken bay leaf and clover. Put some in the bottom of the pan also. Spread the chicken with butter or cover with thin slices of salt pork or bacon, held by toothpicks. Cover the pan tightly and cook for half an hour in a very hot oven. Cook the giblets separately in water and when soft, season. Mash and spread on toast. If the toast is hard, pour a little strained liquid from the giblets over it. Serve the chicken on these slices, garnish with parsley, serve with sauce made from the liquid in the pan and the giblet water. Season with onion, Worcestershire sauce or tomato, or a highly-seasoned tomato sauce. Jellied Chicken. Clean and cut up a 4-pound fowl. Cover with boiling water. Cook slowly until the meat falls from the bones, adding 1 teaspoonful of salt when half-cooked. Remove the meat from the bones. Pick the meat apart and mix the light and the dark, or use only the light if desired. Remove fat CHICKEN BROTH 141 from the chicken liquor; season it highly with salt, pepper and lemon juice. Cook slowly to reduce the broth to about one cupful. Butter a mold and pack the meat in solidly. Turn in the seasoned broth. Set it aside to cool. When ready to serve, dip the mold into warm water and turn out carefully. The chicken may be molded in individual molds and used cold in place of meat or salad. In hot weather it may be necessary to add 1 teaspoonful of gelatin soaked in 1 tablespoonful of cold water to be sure the chicken loaf will be stiff enough to slice. Chicken Broth. One medium sized fowl; 2 quarts of water. Cut lip the fowl as for stewing. Add the water, salt, white pepper, and, if desired, a little chopped onion or celery or both. Cook slowly for about five hours. Remove the meat and let the broth cool. When cold remove the extra fat. Put into glass jars and keep in a cool place until ready to use. If stock is not to be used at once, the fat may be left on. This makes an air-tight covering and helps to keep the stock fresh. CHAPTER XXV. MODIFIED RECIPES FOR CASES REQUIRING SPECIAL DIETARY CONSIDERATIONS. Modification of Recipes.—Rather than change the recipe until the product has lost its identity, it is preferable to modify the menu and eliminate such foodstuffs as are undesirable. Special diet cookery requires individualizing and rearranging of menus to satisfy the diet requirements of the various cases. For certain conditions such as diabetes, an effort has been made to contribute variety to the necessarily limited diet by the modification of recipes. An effort should be made to select food materials which are not dangerous to the patient and build up a combination of foods that represents as nearly as possible a normal meal. This requires ingenuity on the part of the nurse. Diabetic Cookery.—The problem in cooking for the diabetic is to keep within the individual’s carbohydrate limit and still to supply sufficient bulk of food so that the hunger will be satisfied. Such materials as bran, cellulose or agar-agar are valuable in that they are not absorbed and provide the diet with bulky material. Materials can be selected for diabetic cookery that have no food value as mineral oil for fats and agar for eggs, to bind other foodstuffs and coffee as a flavoring agent. It is possible to train a patient’s taste away from sugar. If there is too great a craving for sweets, saccharin can be substituted for sugar, 1 grain being sufficient to sweeten 1 quart of food.

CHAPTER XXVI. DIET FOR TIIE VARIOUS PERIODS OF LIFE. The life of the individual may be divided into five periods: infancy, childhood, adolescence, maturity and old age. Each of these periods has its dietetic needs. The caloric need is relatively higher in infancy than at any other period, because it is the period of most rapid growth. The feeding is an important factor in infancy. The mother’s milk is unquestionably the best food for the baby, and for a number of reasons: 1. The composition of human milk is perfectly balanced and cannot be perfectly imitated. 2. The curd of the human milk as it digests is softer and more flocculent than that of other milk. 3. Breast milk contains vitamins and other metabolic principles which are not found in substitutes. 4. It contains immune bodies which protect the baby, breast-fed babies having greater resistance and not being as susceptible to disease as those artificially fed. The following procedures for infant-and child-feeding1 are recommended: PREPARATION OF INFANT FEEDINGS. Before preparation of feedings: 1. Read the doctor’s orders. 2. Scrub the hands well. 1 The author is indebted to the Clinic in Pediatrics of the University Hospital for advice and assistance in formulating these procedures. PREPARATION OF INFANT FEEDINGS 155 3. Wear a clean gown. 4. Wear mask over mouth and nose in case of upper respiratory infection. 5. Use clean towels. Equipment for Preparation of Feedings.—Sterile towels; sterile forceps; sterile water; sterile cotton squares (4 inches square, to cover milk bottles); sterile absorbent cotton (2d grade—for plugs in nursing bottles); elastic bands; string tags to label bottles; sterile nursing bottles with racks; sterile milk bottles; scales and weights; paper napkins; medicine glass; aluminum saucepans; wooden stirring spoons; 1 knife; 1 fork; 1 teaspoon; 1 tablespoon; wire strainer; funnel; 2 graduates (1000 cc and 1500 cc); dairy thermometer; Dover egg-beater. Materials for Food Preparation. — Sugars.—Cane sugar; lactose; dextri-maltose; karo syrup solution; wheat flour; barley water; whole milk. All utensils used in the preparation of feedings should be separately stored and used for this purpose alone. Dish towels should be reserved for this purpose only, and these should be washed daily by the nurse who prepares the feedings. The utensils used to make feedings are to be boiled ten minutes and placed on a sterile towel ready for use. All milk, before and after its preparation, is to be kept on ice; bottles or any other containers of milk must not be left for any length of time uncovered. After a formula is prepared the best method is to put the amount ordered for each feeding into a separate nursing bottle. That is, if the baby’s order is for 120 cc at each of five feedings, put 120 cc of the prepared food in each of five nursing bottles. It is then ready for immediate use. Plug each bottle with cotton and keep it on ice, 156 DIET FOR THE VARIOUS PERIODS OF LIFE If there are not enough nursing bottles available to do this, the entire quantity for feedings may be put into a quart milk bottle, which is to be covered and placed on ice. Then the desired amount for each feeding may be poured out into a sterile nursing bottle and heated for use. Never heat the whole quantity prepared in the quart bottle. Heat only the amount required for each feeding in the small nursing bottle. A nipple should have three small holes, so that when the bottle is inverted the milk will just drip out slowiy. A No. 10 sewing needle heated red-hot over a flame makes holes of the proper size for ordinary use. Stick the blunt end of the needle into a cork; it can then be heated and handled with ease. Very thick milk mixtures, such as protein milk or lactic acid milk, require larger holes in the nipples. Occasionally a babe who nurses very slowly will also require a nipple with larger holes. A child should spend at least ten minutes, and not over twenty minutes, in taking an ordinary milk preparation. He should lie on his side or may be held in the nurse’s arms while feeding. The bottle must be tilted, so that the milk comes above the neck of the bottle or the babe will nurse in air. Never, under any conditions, prop the bottle and leave the babe alone with it. It is well to stop the feeding two or three times and hold the babe upright, gently patting the back to help him regur- gitate gas. This prevents vomiting. After use, the bottle and nipple are to be washed in cold the nipple is then to be boiled for two minutes and placed in a jar of sterile boric acid solution or and is ready for use at the next feeding. The bottle is to be boiled and plugged with sterile cotton, ready for its succeeding use. PREPARATION OF INFANT FEEDINGS 157 To heat milk to feed a babe, place the bottle containing the exact amount for one feeding in a pan of water at 105° F. for five minutes. Do not remove the cotton plug from the bottle or put the nipple on the bottle until it is ready for the baby’s feeding. The nurse who prepares feedings is responsible for the milk refrigerator. She must clean it well every day. Twice a week the ice and ice tray must be removed for more thor- ough scrubbing, and the drain must be flushed with sal soda. As soon as the milk is delivered in the morning the bottles must be washed and put on ice until time to prepare feedings. After the 2 p.m. feeding each day, if any prepared food remains unused it is to be thrown away and fresh prepara- tions used for the 6 p.m. feeding. Milk Mixtures in Common Use.—Malt Soup.—A. To a few tablespoons of milk add 5 level tablespoonfuls of wheat flour and rub to a thick paste. Make up to 11 ounces with whole milk by adding the milk slowly, stirring constantly, and putting the mixture through a strainer if there are any lumps in it. B. Dissolve 4 tablespoonfuls of malt soup extract in 22 ounces of warm water. C. Mix A and B and boil for three minutes, stirring con- stantly. Strain, bottle and keep on ice. Five Per Cent Oatmeal Water— Add 15 grams (| ounce or 2 rounded tablespoon fills) of dry uncooked oatmeal to 600 cc (20 ounces) of water. Add salt, 1 teaspoonful to the quart. Boil down to one-half the quantity. This takes from one and a quarter hours to one and a half hours. Strain, bottle and keep on ice. Buttermilk' Mixture— To a few tablespoonfuls of buttermilk add 2 level tablespoonfuls of flour to make a thick paste; stir well to remove lumps. Make up to 1 quart with buttermilk. 158 DIET FOR THE VARIOUS PERIODS OF LIFE A. Bring to the boiling point; remove from fire for five minutes. B. Bring to the boiling point again; remove from fire for five minutes. C. Add 4 level tablespoonfuls of eane sugar and bring to the boiling point the third time. (A, B and C, take about twenty minutes.) Make up to 1 quart with water if any has boiled away. Bottle and keep on ice. Milk Mixtures.—Modified Milk: A. Sugar, kind and quantity ordered. B. Sterile water or cereal water as ordered. C. Milk in proportions ordered. Mix A, B and C well, boil three minutes, stirring con- stantly; bottle and keep on ice. Routine Nursery Formula Used to Complement Feeding of Newborn Babes.—I cow’s milk; f lactose solution, 10 per cent. Protein Milk, Albumin Milk, Eiweiss Milk, Casein Milk.— Heat 1000 cc of whole milk to 100° F. and add 8 cc essence of pepsin. Set it aside until it coagulates (about thirty minutes) and forms a firm curd. Cut in squares with a knife and let stand until the whey separates (about thirty minutes). Place a double thickness of gauze over a strainer, put the curd into it and let it drain for thirty minutes to one hour, or until the whey is all drained off. Usually 700 cc of the whey will be thus drained off. Do not stir the curd or squeeze it while it is draining, as this will toughen it. Put the remaining curd in a fine wire sieve and mash it through with a wooden spoon. A pint of sterile water and a pint of buttermilk are to be added while it is being put through the sieve. Put the whole mixture through the sieve three times or until the curd is finely divided. Beat PREPARATION OF INFANT FEEDINGS 159 for two minutes with a Dover egg-beater. The finished product should measure 1000 cc. If dextri-maltose is ordered in protein milk, add the necessary amount to the sterile water and heat it until the sugar dissolves before adding it to the curd. Do not heat protein milk over 100° F., and do not try to boil it. Lactic Acid Milk.—Symbols used in ordering lactic milk: S. L. M. = skim lactic acid milk or buttermilk. W. L. M. = whole lactic acid milk. Iv. S. = karo syrup—50 per cent solution. To prepare W. L. M.: Sterilize 900 cc of whole milk by boiling two minutes in a saucepan; place it in a sterile milk bottle, cover and let it stand until below 100° F. Then inoculate with Bulgarian bacilli, about 1 tablespoonful of culture to 1 quart of milk. Place bottle of milk in incubator, keeping at 100° F., for twelve hours, or until the milk coagu- lates. Remove and place it on ice until ready to prepare formula. S. L. M. is prepared in the same way when using skimmed milk in place of whole milk. To prepare karo syrup, mix equal parts of “blue label karo syrup” (brown syrup) and water and bring the mixture to the boiling point in order to sterilize it; place in sterile bottle and keep it on ice. To prepare lactic milk formula: Strain the lactic milk before using; mix with vTater and karo syrup solution in proportions ordered; bottle and keep it on ice. Do not boil lactic milk and do not heat over 100° F. Keep an extra bottle of S. L. M. in the refrigerator to use as a culture. The culture should be renewed every two or three weeks. Thick Cereal Mixture — Use farina, Pillsbury’s wheat cereal or cream of wheat. To make 15 per cent of cereal mixture, add 150 grams of 160 DIET FOR THE VARIOUS PERIODS OF LIFE cereal and 1 teaspoonful of salt to 1000 cc of water.' Add 1 teaspoonful of salt. Have the water actively boiling in the inside container of the double boiler, placed directly over the flame; sift 150 cc of dry cereal into the water slowly, stirring constantly and boiling directly over the flame for two minutes. Then place the inside part of the double boiler in the outside kettle, containing water, and cook the mixture over a low flame for one hour, stirring frequently. To Prepare lloos’ Albumin Milk.—Add 90 grams of Hoos’ albumin milk powder to 1000 cc of warm sterile water. Measure the water, pour it into a pan and place the powder on the surface of the water; beat it with a Dover egg-beater until well mixed. Do not place the powder in the pan first and pour the water on it, as it will not mix properly. After mixing, pour the milk through a fine wire sieve or strainer, rubbing it through with a wooden spoon. Add dextri-maltose in percentage ordered; dissolve the latter in 30 cc of the original 1000 cc of warm water before adding it to the whole. Bottle the mixture and keep it on ice until needed for use. DIETS FOR CHILDREN. Ages at Six Weeks to Two Months.—Orange juice strained; begin by giving 1 teaspoonful, diluted with equal parts of water, once a day, increasing it to 1 tablespoonful twice a day.

Meals should pot be eaten in haste or carried from the table. No 164 DIET FOR THE VARIOUS PERIODS OF LIFE dislikes of certain foods should be encouraged. Xo lunching should be allowed between meals. Simple sweets should be served at the table to satisfy the craving for such foods. This can be achieved with simple desserts and fruits, either dried or cooked; sponge cake, cookies or sweet chocolates given at the end of the meal. ADOLESCENCE. Adolescence marks the close of childhood. The demand for food is active as adolescence covers a period of both functional and structural activity. There is a tendency toward food idiosyncrasies and an abnormal appetite for sweets and protein foods, with little inclination toward fats. During this period the appetite is not always a safe guide and the meals should be carefully planned and nicely served. If the meals are regular and substantial, yet attractive, they may modify the excessive craving for sugars. It is well to provide a liberal, well-balanced diet, not neglecting the green vegetables, fresh root vegetables and fresh fruits. The amount of food required is an individual problem, depending upon the degree of functional activity. Tea and coffee should be restricted. Adolescence continues up to a variable age, between twenty to twenty-four years for the female and twenty-four to twenty-seven years for the male. MATURITY. The adult has a more rapid digestive rate and digestive power is greater than at other periods of life. The amount of food necessary to maintain nutrition is influenced by age, sex, extent of body surface, weight, occupation and climate. Digestion is more robust in the cold days of fall and to the end of winter, while a decline in digestive power occurs in OLD AGE 165 the spring. This calls for seasonable variations in the diet, making it easier of digestion during the hot weather. More substantial foods and those of higher energy production are required during the winter. A general rule to follow in planning the dietary of the normal adult is to allow 10 per cent of the total calories in protein, 30 per cent in fats and 60 per cent in carbohydrates. Six to 8 pints of water a day should be taken, half of which may be counted upon as contained in the foodstuffs. Old age decline begins at an age varying between sixty and seventy years. Structural changes occur in the body and functional activity should be less strenuous. The mus- cles lose tone and mass. The organs of digestion are apt to share in this degeneration, making it necessary to decrease the demands upon the digestive tract. The teeth may be lost and mastication therefore becomes difficult. Foods that are mechanically easy should be served. The diet should depend largely upon the activity and digestive ability of the individual. In most cases it should consist of simple, easily digested food containing a relatively small amount of protein. If there is difficulty in mastica- tion the food may be minced or ground. Protein may be supplied in the form of milk, eggs,* chicken, fish, roast or scraped beef. An abundance of water should be taken. The meals should be light but may be frequent, nourishment being given between meals and before retiring. OLD AGE. BIBLIOGRAPHY. Atwater: Bulletin No. 142, U. S. Department of Agriculture.

There are certain general conditions which govern the dietetic treatment of the sick. 1. The patient’s nutritive condition prior to the attack with particular reference to weight. Weight is an index to the nutrition of the individual. In determining caloric need, the normal weight is used. 2. The nature of the attack, whether it is a chronic, con- tinuing or an acute and self-limited disorder. 3. The intensity or virulence of the attack, the index to which is commonly the temperature chart. It is held that internal chemical changes are accelerated three times over with every 10° increase of temperature. 4. The localization of the disturbance is a dietary con- sideration. 5. The condition of the digestive tract is to be studied with reference to the patient’s digestive power. 6. Conditions of elimination must be taken into account. The Tray.—In planning food for the sick, economy, except- ing among the very poor, should not be a prime consideration. Whatever will hasten recovery should be given, provided it complies with the doctor’s orders. The nurse has a better opportunity than the doctor to study the likes and dislikes of the patient. If the diet the doctor orders does not agree with or is disliked by the patient, the fact should be reported to the doctor for his direction of a change. While a knowl- edge of dietetics is necessary to enable one to substitute one food for another, in serious cases this knowledge should be directed by the physician’s instructions. PRECAUTIONS 167 Hospital diets may be classified as follows: Liquid diet. Semisolid diet. Light diet. General diet. Special diet. Milk Milk toast All items included Regular diet, Diabetic, Buttermilk Cream toast under semisolid excluding: cardiac, Eggnog Cereals (well- diet plus: Pork salt-free, Albumins cooked) Fruit (cooked) Corned beef etc. Orangeade Eggs (creamed Fruit (raw except Veal Lemonade or poached) bananas) Cabbage Broths Soups (strain Bread or toast Cake (except- Cocoa out all coarse Bacon ing sponge Sherbet vegetables) Green vegetables cake) Tea Custards (excepting cauli- Pastry Coffee Cornstarch flower, radishes, Hot breads bruit gelatin Fuit juices Ice-cream Junket Thin gruels pudding Rice Tapioca cabbage) Baked potato Vegetable salads White fish Baked or broiled halibut Small amount of white meat of chicken Scraped beef Creamed sweet- breads Fried foods Precautions.—The following details should be noted in serving food to the convalescent: 1. Punctuality of meal service. Most people develop an unconscious habit in the matter of meals, and if they are delayed the appetite in the convalescent may be gone. 2. Noise and odor in the preparation of food are to be avoided. 3. Food selection is not to be discussed with the patient. If possible each tray should be a surprise, governed by a familiarity with the likes and dislikes of the patient. 4. The patient’s interest in meals is usually exaggerated. The diversions of the sick-room are limited and the patient 168 DIETARY CONDITIONS OF THE SICK is much affected by his immediate surroundings. For this reason the tray and its appearance are very important details. A carelessly prepared, unattractive tray may completely destroy the appetite of a refined or fastidious patient. 5. If the patient can sit up for only a few hours, utilize this time for the serving of meals. 6. If the diet is limited the patient will enjoy the service of meals in courses instead of the appearance of a full tray. 7. Serve only small quantities of each kind of food. A second serving may be brought if desired and the danger of a loss of appetite will be avoided. 8. Foods to be served hot must be hot, not lukewarm; foods to be served cold must be cold, but not iced. 9. Do not fill glasses over two-thirds full. 10. Serve the food in a form easy for the patient to handle and choose foods whose nutritive values are high in propor- tion to their bulk. 11. If beverages are to be served alone, use a small tray or plate covered with a doily or small napkin. 12. Do not allow food or dishes to stand for any length of time in the sick-room; remove them as soon as possible after the meal. If anything must remain for a short time it should be covered. To Prepare the Tray. —1. Cover the tray with a clean tray cloth. The cloth should be immaculate and free from creases or wrinkles. 2. Use the most attractive silver and daintiest china and glass available. 3. Use some simple decoration, as a single flower in a small vase. Even a bit of green is better than no decoration. 4. The tray should not have a crowded appearance, but should include everything needed for the meal.

In self-limited, acute fevers of short duration, as in measles, mumps and scarlet fever, the diet is not important. A light diet may be used. Fluids should be forced. In fevers of long duration, as in typhoid, typhus and bronchopneumonia, the diet is an important factor. Nutri- tion must be maintained and easily digested foods must be chosen. A very high caloric diet may be used and inroads upon the body tissues prevented if the food is carefully selected and prepared. In typhoid the intestinal mucosa is damaged and coarse or unstrained food which may further break it down must be avoided. Liquid diet and soaked or strained foods are used until the temperature has remained normal for two days, and then unsoaked crackers and toast may be added. At the end of a week of normal temperature the more DIETETIC TREATMENT OF FEVERS 171 delicate meats are permitted, after which a gradual return to a general diet is desirable. Dietary of Typhoid Fever.—Until the temperature has been normal for two days, give the following diet, allowing at least 3000 calories daily, in 6 feedings, at the following hours: 8 a.m., 10 a.m., 12 m., 2 p.m., 5 p.m., 8 p.m. Force the use of fluids.

Diabetes. — Diabetes is characterized by a diminished ability to utilize the carbohydrate foods and the consequent appearance of sugar in the urine. The diabetic has a definite limit of tolerance for carbohydrates, and beyond this limit the sugars are excreted. It is impossible to completely cut off the carbohydrate supply, as this causes the formation of 174 DIET IN DISEASE dangerous products, acetone bodies, which arise in the course of the metabolism of the fatty acids and give rise to a form of intoxication known as acidosis. It is also possible that the diabetic may convert protein into sugar. In this event the question of diet is further complicated, since all food groups must be considered. Several methods are used in the treatment of diabetes, the fundamental principles of which are essentially the same. The chief aim is to reduce the diet until the patient is both sugar- and acetone-free. He should remain in hospital until this is accomplished and the carbohydrate limit has been established. “The Joslin treatment” is recommended. The Joslin treatment for mild and moderately mild dia- betes (cases not hospitalized) consists in a gradual reduction of the amount of carbohydrates; omitting, first, sugar, as such, and then further gradually reducing the carbohydrate intake until the patient is sugar-free. The Joslin treatment for more severe cases (hospitalized patients) is (1) to omit fats; (2) omit proteins; (3) lessen the carbohydrates until the patient is getting less than 10 grams; and then starve. During starvation force the fluids, giving broth, tea and coffee and thrice-cooked vegetables at meal times. Starvation is continued for four days or until the urine is sugar-free. If not sugar-free at end of four days, give \ gram protein or 1 gram carbohydrate per kilo for two days, and then starve for three days; then give the same amount of carbohydrate and protein again for four days and fast one day. When sugar-free, add 5 to 10 grams of carbohydrates daily until sugar appears in the urine; then fast until sugar- free; then reduce the carbohydrates to § of this tolerance and add 15 to 20 grams of protein daily until 1 to If grams per DISORDERS OF METABOLISM 175 kilos are given; then add fats until caloric requirement is reached. First day: Carbohydrate . . . 150 grams Protein 75 grams Fat 0 grams Second day: Carbohydrate . 150 grams Protein 35 grams Fat 0 grams Third day: Carbohydrate ... 75 grams Protein 0 grams Fat 0 grams Fourth day: Carbohydrate ... 38 grams Protein 0 grams Fat 0 grams Fifth day: Carbohydrate . .. 19 grams Protein 0 grams Fat 0 grams Sixth day: Carbohydrate ... 9 grams Protein 0 grams Fat 0 grams Seventh day: Starvation The Allen treatment differs from the above in that fasting is begun at once and continued until the patient is sugar- free. After the patient is sugar-free the diet is similar to the above, excepting that alcohol is included in the diet. Starvation.—As a control, one day of starvation in each week is suggested. It is advisable in selecting the foods to use those of low carbohydrate content. Diabetics will show sugar on a diet which contains the 20 per cent carbohydrate containing vegetables, while they will continue to use the same number of grams of carbohydrates in those vegetables and fruits which contain 10 per cent or less, and will remain sugar-free, 176 DIET IN DISEASE Typical Diabetic Diet.

As the bile is needed for the emulsification and absorption of fat, this type of food must be restricted in the dietary under these circum- stances. Another function of the liver is the conversion of the blood-sugar into glycogen and its storage, as a glycogen- forming power may be impaired, so that in this event the carbohydrate foods should also be restricted. In an acute catarrh of the bile ducts the patient is sub- jected to a period of dietetic rest and the digestive tract is cleaned out. Following this a light diet is indicated, elimi- nating fats and sugars. Typical Fat-free Diet. Breakfast: Fresh or cooked fruit; shredded wheat; skimmed milk; dry toast; egg; coffee. Dinner: Broiled or boiled fish (halibut); lean meat or fowl; baked potato; spinach with lemon juice; green peas; bread; tea with skim milk; cornstarch blanc mange. Sujiyer: Tomato broth with rice or crackers; broiled sweetbreads; cottage-cheese salad; toast or bread; baked apple; coffee with skimmed milk. Obesity.—This condition is usually the result of the exces- sive use of carbohydrate and fat food, with a lack of exercise. A quantity of food which may be safely consumed by one individual will prove excessive in another, the difference depending upon the digestive and metabolic power, the degree of functional and especially of muscular activity and the eliminative efficiency. 178 DIET IN DISEASE Diet for the Obese. Breakfast: Cup of black coffee with skimmed milk, without cream or sugar; raw fruit (orange, apple, pear, grapefruit); eggs (1 creamed or 2 boiled or poached); toast (1 or 2 small slices, 10 to 20 grams, usually without butter, or a bran muffin). 9.30. Coffee, one cup; bouillon (250 cc); skimmed milk, butter-milk or fruit. Luncheon: Clear soup (120 cc); moderately lean meat or fish (100 grams) or eggs; two kinds of fresh vegetables (50 to 100 grams each), as spinach, lettuce, onions, lentils, beets, carrots, cabbage, cauliflower, string beans, celery or squash; bran muffin, one; tea, one cup. Dinner: Moderately lean meat or fish (100 to 150 grams); two varieties of green vegetables (50 to 100 grams each); salad, fruit or vegetables, with small quantity of French dressing; raw, unsweetened cooked fruit (orange, grapefruit, apple, pear or grapes); coffee, one cup.

Fish (excepting shad, fresh salmon, sardines, mackerel, blue fish and all fried fish). Thin soups in moderation. Eggs in any form except scrambled, fried or omeleted. Fruits: All fresh varieties (excepting bananas); berries (without cream or sugar) cookec( with saccharin. DISORDERS OF METABOLISM 179 Vegetables: String beans, water-cress, lettuce, radishes, cucumbers, asparagus, green peas, Brussels sprouts, cabbage, cauliflower, onions, celery, tomatoes, spinach, squash, beets, turnips, carrots, parsnips. Miscellaneous items: Tea, coflee, skimmed milk, ginger ale; desserts made of gelatin or Irish moss with but little sugar; use saccharin if possible; bran biscuits. Goiter.—Goiter is very common around the Great Lakes and in regions far from the sea, such as the mountains of Scotland and Switzerland. It is due to a lack of iodin in the soil, which results in a lack of iodin in the diet of those living in these localities. Adding suitable amounts of sodium iodide to the diet will correct this deficiency and provide a means of preventing goiters. Kellogg states that “The diet should be made antitoxic, including liberal quantities of greens, and particularly the following foods, which analysis has shown to contain iodin in appreciable quantities; turnips, melons, lettuce, beets, tomatoes, French beans, green peas, radishes, carrots, parsley and potato. Observations of Chalmers Watson suggest the special value of oatmeal in the feeding of persons suffering from simple goiter.” The Purin-free Diet.—Uric acid is supposed to be derived from the nucleoproteins. The pur ins may come from the breaking down of nuclear material in the food or in the body tissues themselves. In gout, uric acid is deposited in the joints, and these cases are placed on a purin-free diet. Tea, coffee and cocoa are forbidden. Purin-free Diet. Breakfast: Grapefruit; cream of wheat; milk; cream; eggs; butter; bread; sugar; cereal coffee. 180 DIET IN DISEASE Dinner: Cream of corn soup; mashed potatoes; bread; milk; baked apple with whipped cream; sugar. Supper: Creamed rice with cheese; scrambled egg; toast; butter; milk; pear sauce; cereal coffee; cream; sugar.

GA STRO-INTESTINA L DISORDERS 181 GASTRO-INTESTINAL DISORDERS. Gastritis.—The first step is complete starvation until the vomiting ceases, which may be a matter of twelve to forty- eight hours. The first foods given may be koumyss, butter- milk, peptonized milk, orange albumin and ginger ale. The amount of the feeding should be very small at first; only a spoonful every half-hour, gradually increasing the amount and lengthening the interval between feedings. When the acute stage is past, add strained gruels made of cereals and diluted with milk. If these are tolerated, gradually increase the diet, giving semisolid foods at first and slowly reaching a general but simple diet. All coarse, highly-seasoned food must be avoided for an indefinite time. Chronic Gastritis.—A gastric test meal is necessary before planning a diet for this condition. The disease may be com- plicated by gastric atony, hyperacidity or hypoacidity. The diet should follow that of acute gastritis—bland, easily digested foods being indicated. If hyperacidity is present avoid acid foods, coarse foods, spiced foods and alcohol. Both very hot and cold foods are to be denied. If accom- panied by hypoacidity, restrict the use of meats; avoid soups; take water in small quantities, but otherwise follow the diet for hyperacidity. Seven-hour Motor Meal. Object: To give a balanced meal to test the normality of gastric digestion the following will serve: steak; mashed potatoes; tomatoes; bread and butter; tea and cream; prune whip; one-half cup of raisins. Any well-balanced meal, with the addition of the raisins, may be used in place of this menu. 182 DIET IN DISEASE The ineal is usually given at 1 a.m. and removed by gastric expression at
