NIAGARA SQUARE BUFFALO, NEW YORK Copyright. 1017. by the I niversity of Buffalo Introduction TWV. ])ast few months have more and more impressed upon Americans the need of ])reparedness in every department of life. Perhaps some of the alarm created is unnecessary ; but with regard to the pro- duction, conservation, and prudent use of food, our concern should be timely. In presenting the bulletin upon "Food Pre- paredness" the University of Buffalo feels sure that it can render the people of this vicinity valuable advice and assistance. The paper has been prepared by Albert P. Sy, Ph.D., Professor of Chemistry, who has given the subject of food and diet especial attention for many 3'ears. The series of bulletins of which this forms one issue will be practical in character and popular in style, devoid of the technicali- ties wliich so often render scientific infor- mation forbidding and useless. We hope for the widest possible distribution of '. these tracts of the times, which may be had for the asking from the Secretary of the Faculty of Arts and Sciences, at Town- send Hall. Committee on Publications. v' ©CI.A46903:3 m 29 1917 Food Preparedness An adeqiiaU' food su{)ply and a careful study of diets arc the basis of national well-being. Education, medical attention, econ- omics and recreation are of considerable importance but each and all depend upon jjroper nourishment of the physical body. Until recent years little or no attention has been paid by most people to matters of food and diet; the first serious agita- tion in this country does not date beyond the memory of those who read this. I refer to the time when the question of a Pure Food Law began to be seriously considered by the people and their representatives in Congress. After several years of fight- ing against the unscrupulous and greedy food interests, our pres- ent Food and Drugs Act became a law, in June, 1906. Since that year more progi-ess has been made in the study of foods and diets than in all the time preceding it. The Bureau of Chemistry of the United States Department of Agriculture with its branch laboratories throughout the country has made it un- profitable to adulterate and misbrand food products. The pub- lic hardly appreciates the great service rendered by this branch of government inspection. It should be said, however, to the credit of the large majority of food manufacturers and dealers that they are jealous of their reputation to supply the public with honest and correctly branded foods. The public knows what to expect of foods bearing certain labels — they buy these foods with confidence in their purity. Several factors were in- strumental in calling the public's attention to a serious study of foods : First, the {•(>ntr()\ crsy j)re(cding tlie enactment of tlic Pure Food Law. 'Second, the adulterations discovered and published as a residt of enforcing the law. Third, the rise in prices, i)artially a result of the cru- sade for better foods. 3 Not until there oecurred an appreciable rise in prices did the majority of our people begin to paj' serious attention to foods. As long as the supply seemed abundant and prices reasonable, very few people paid any attention to matters of diet. That the time is at hjyid for most serious and earnest study of our food problems is a statement which surely does not admit of debate. If, under ordinary circumstances, such a study involves a variety of factors which make the problem complicated, what is to be said about the present most extraordinary conditions.^ And what about conditions of the immediate future.^ A few j'ears ago the person who was not writing or talking about "efficiency" was not up-to-date. Efficiency found its waj' into every con- ceivable nook and corner of our educational^ professional, indus- trial and agricultural life. But lately another word has been coined — "preparedness". It is not an exaggeration to say that with characteristic American enthusiasm we promptly pi-oceeded to lose our heads over this new word, and this very fact shows one thing more plainly than anything else, namely, our unpreparedness. Even now, after the preliminary excitement has partially subsided, the word "pre- paredness" to most people means soldiers, guns, cannon, cruisers, submarines, air-planes, fortifications and explosives. Those whose thoughts on preparedness penetrated a little deeper dis- covered that it includes doctors, nurses, hospitals and medical supplies. By the time these words are in print, it is hoped every- body who is capable of a serious thought will realize that just as important and vital as anything else joertaining to preparedness is the question of food. Feeding and fighting arc two inseparable terms. A minute's reflection should suffice to show the utter uselessness of any scheme of preparedness that does not include an elaborate study of the food problem. The time is at hand when we, each of us. must think and act seriously. Preparedness must have a personal meaning. There can be no national preparedness without indi- vidual preparedness. The first step in patriotism is personal preparedness. There can be no preparedness without health, 4 and health is impossible without correct personal habits and adequate food. National preparedness resolves itself, therefore, into correct living which in turn is based upon proper nourish- ment, not only for today but for tomorrow. At ordinary times and under ordinary circumstances, questions relating to an ade- quate diet involve no great complications, but circumstances are most unusual ; the supply of food seems limited, something which we as a wasteful nation never before believed possible. The one factor which has helped more than any other to bring us to our senses about our food is its cost. "Money talks", and food prices are fairly shrieking at us at ever}' turn, a state which has a serious meaning to everybody alike. The easiest way to interest most people in any kind of a problem is to force their attention to the question of cost. But, let us come back to preparedness. I can serve my coun- try best by being prepared personally and by helping others to a similar condition. The person with all kinds of advice and criticisms who is not personally prepared nor doing anything to help others presents an argument without force. The importance of food to personal preparedness is not de- batable; it is an axiom. Teachers, preachers, doctors and otliers who come in contact with the public should study foods and diets ; physicians particularly can be of great service. There is great need of instruction in Personal T^ 1 food values, dietetics and personal hvgiene. Prices Preparedness '■ "^ . tell their own story and are educating the pub- lic in matters of food and diet, and the physician can add scien- tific argument to that of prices. Teachers of all grades, from kindergarten to university, should be required to study foods. An outline for study, including a list of books and other literature of the subject, should be provided. There are parents who are doing themselves an injustice and who are neglecting a principal duty of parenthood by their indift'erence toward their own and their cliildren's food problems. 5 Many people arc unprepared because of circumstances over wliich thej' have no control. But many more arc unprepared mainly because of indifference and preventable ignorance. I use the term "preventable ignorance" because anyone really in earnest has little difficulty in becoming well informed on matters of food and diet by making use of our modern library facilities, attend- ing lectures and by reading journals and magazines. A word of caution is necessary at this point. Much that is said or written is misleading or imtrue. Our daily newspapers often contain much misinformation. But it should be remembered that our newspapers are not scientific journals where accuracy counts most ; they are rather the medium for the exchange of ideas where people express their opinions. Let us now consider briefly some of the elements that make for personal preparedness. First, one should know something about modern theories of diet. Many excellent books exist on this and related subjects, and can be found in almost any modern library. Particularly , , , good is A. Brvce's Modern T h e o r y of Diet Modern " , , „ ■ , _^. . j, t. ' ,. , . „ and his smaller work on Dietetics. Bv spendmg theories ot , . „ , i , . ,. as much time on one oi these books as is re- diet 111 1 <rincipal chem- ical constituent the element nitrogen in such a form as to be readily assimilated and used by the body. These protein foods p . arc absolutely essential for the building up and ,. J repairing of our bodv. Without them there roods ' would be no dcveloj^mcnt and the animal would soon perish. These foods are sometimes called the nitrogenous foods. As cxamj^lcs of this class of food stuffs we have the white of an egg cchicJi is very nearly pure protein, con- iaininrj about 86% of icater. Other jiroteins are the lean part of all meats and fisli. the gluten in wheat (other grains also contain pi-oteins), the casein in milk and cheese. Many other foods con- tain proteins. Some of the protein foods are cheese, 26% ; pea- nuts 26%; beans 23%; meats 19%; fish 17%; eggs 15%; what 12% ; oats 12% ; corn 10% ; bread 9% ; rice 8%. A brief study of these percentages will indicate how substitution might be made. Cheese, beans or even bread might at times be used partl}^ or wholly in place of meat. Second: Another important class of foods consists largely or entirely of what chemists call carhoJiydrates. The various sugars and starches arc representatives of this class. Pure car- „ , , bohvdrates such as the sugars and starches do Larbony- ■ "i , /• , not contain nitrogen and can thereiore not be substituted for proteins. They are called the heat- and energy-producing foods. The important foods of this class and their percentage of sugar or starch are: Cane and beet sugar over 99%; hard candies 96%; honey 81%; jelly 78%; raisins 7G% ; rice 76%; wheat 74%; corn 73%; oats 70%; molasses 68%; beans 60%; bread 53%; bananas 22% ; grapes 19% ; potatoes 18% ; apples 11'%. Third: The third imi)ortant class of foods is known as fats. Lard, olive and peanut oils arc pure fats; they contain no nitro- gen and will not do the work of protein foods. The function of *Food charts, in colors, publislicd b\- U. S. Department of Agriculture. 7 J, tlu' fats in metabolism is similar to that of the carbohydrates, namely to supply lieat and energy. The fatty foods with a Iiigh percentage of fat arc as follows: Lard, olive and peanut oils 100%; butter 83%; bacon (57%; walnuts (53%; peanuts 39%;" cheese 31%; cream 19%; meat 18%; eggs 11%. These three classes of food principles alone are not sufficient to produce growth and energy in the human body ; a small amount of a number of inorganic substances called "salts" is necessary. These sails are sometimes referred to as "viineral matter". The chemist often uses the term "ash" and has I'cfercnce to the resi- due after burning a food. Foods naturally contain the necessary amount of mineral matter or salts. The addition of common table salt to our foods is not necessary unless it makes them more palatable. Water, of course, is necessary in our diet and it plays a much more important part than is generally supposed or imderstood. Most foods contain water, and although some people seem to get ™, along with practically no water other than Water . '^ . / . , " ,. , ^ i is contained in the solid toocis they eat, most of us add water to our diet cither as water or beverages tliat are largely water, such as tea, coffee, milk or cocoa. The percentage of water is usually high in vege- table foods. Celery contains 95% water; milk 87%; oysters 86% ; apples 85% ; fish 80% ; potatoes 78% ; eggs 74% ; meat 62% ; bread 35% ; cheese 34% ; honey 18% ; butter 13% ; lard, olive oil, peanut oil, and sugar contain no water. One often hears the statement that peojile do not drink enough water. This is no doubt true. I cannot let the o))i)ortunity pass without call- ing attention to the old but erroneous notion that water should be drunk between meals, not during meals. This idea that _. . , . water at meal time interferes with the digestive Urinking „ . , . , process is still quite prevalent, even among pliy- , sicians. Newspaper and magazine food "ex- perts" almost invariably tell us not to drink with meals. Let it be stated most emphatically that drinking water with our meals is not a liarmful or undesirable practice, but is a decidedly beneficial one. This has been proved repeatedly by rigid scientific experiments. It is now known that water, and fluids generally, stimulate the secretion and flow of gastric juice; water also materially aids and hastens the process<'s of diges- tion and assimilati(m. It is ))hysiologically correct to start a meal by drinking water or eating soup. It has been ])roved that a cocktail or other high alcoholic drink at the beginning of a meal interferes with digestion. Nearly all foods lontain more or less indigestible matter which is classed under the term "crude fiber". Although it is indigestible and does not take any part in metabolic processes P , directly. it serves an important purpose. ni namely to increase intestinal peristalsis which in turn aids in the absorption of food and elimination of waste matter. Vegetables, fruits and grains contain considerable crude fiber, and, partly for this reason, these foods are valuable and should be included in our daily diet list. Our objection to refined foods is that frequently they con- tain no crude fiber. Until recently the com))arison of foods has been studied with reference to their content of protein, carbohydrate, fat, mineral matter, water and crude fiber. During the last few years, how- ever, it has been discovered that normal metabolism can be main- tained only when, in addition to the above mentioned constitu- ents, our foods contain a certain amount of substances called "vitamines".* The exact chemical nature of vitamines is still un- known, but there is no doubt that a diet which is deficient in these substances produces serious nutritional disturbances. Dis- eases such as beri-beri and pellagra are called "deficiency dis- eases", and it is believed are due to the lack of vitamines in the diet. A fairlj^ well mixed diet, particularly one which includes some raw foods and is not largely made up of refined foods, con- tains enough vitamines for maintaining normal metabolism. *A. Seidell, Reprint 325, Public Health Reports, Published by the United States Public Health Service, Washington, D. C. r» 1 ^ i_-T^ jtn addition to havin<>- the correct chemical Falatabihty r composition, foods must be palatable; they must j^gjjjg look and taste rii>ht. Unpalatability interferes seriously with digestion. Not until our atten- tion is called to it do we notice that the flavor of food receives a very considerable amount of consideratiim. This phase of our diet has been carefully stiulied by physiological chemists and others.* One of the chief aims of the instruction in cooking, and preparation of foods, in our modern domestic science courses is to make our meals as appetizing and palatable as possible. And just now while we are facing serious food problems, such as a restricted choice, our cooks will find it well worth while to de- vise methods for making available foods palatable. Closely related to their chemical composition is the nutritive value of foods. This is commonly known as "food value" and for want of a better method is expressed in terms of heat TV, . . calories. The expression for example. "1200 INutntive \,, , , p , 1 calories per pound means that the food in values question, when one pound of it is burned. yields 1200 calories of heat. The processes of metabol- ism in the body resemble burning, and a pound of such food yields nearly 1200 calories of heat. In calculating food values the principal food materials. — protein, carbohydrates and fats — only are considered ; the min- eral matter and water do not enter into the metabolic processes to produce heat or energy. Bread furnishes 1180 calories per pound and three pounds would supply approximately the food value necessary for one day. Beef-steak is slightly less nutritive, being rated at 1090 calories per pound. Sugar produces 1810 calories per pound and a little less than 2 pounds contains the energy for a day's work. Most people will be surprised to learn that one and one-third pounds of peanuts (shelled) at 2485 calories per *H. T. I'inck, Food iind F!a-vor, Century Co. 10 pound contain the equivalent of a day's food. Milk ))roduees only 315 calories per pound, while olive oil and lard are each rated at 1080 per pound. The table at the end of this pamphlet shows calories per jiound of our common food materials. It will be noted that fruits and vegetables and other foods with a high percentage of water have a low calorific or food value, while those rich in fat have the highest values. An average man doing ordinary work requires daily enough food to produce from ;jOOO to ;^500 colorics of heat. Laborers doing hard work require ccmsiderably more, while peo])le doing but light muscular work can get along with 2000 calories. These heat calories should be produced by foods constituting a mixed diet; that is, containing some of each of the food principles described. Enough of this mixed diet .should be eaten to maintain a nearly constant body weight in the case of adults ; a considerable gain or loss in body weight can in most cases be attributed to an ex- cessive or deficient diet. One should eat only palatahle food and only rchen liiingry. We should eat. not because we feel it a duty or necessity — we should enjoy our food; wc should eat for the pleasure it gives us. Food should be kept in the mouth until all taste or flavor has been chewed out of it. The flavor of food should be our guide as to ■ichat to eat; hunger should cr j)rices or expensive cheese would ed'eet no eeonom}'. The time is not far distant when vegetable proteins not now in use as human food will be common. At ]) resent they are utilized in feeding stuff mixtures for cattle and horses and hogs. ^j , , I refer to the bv-products of the vegetable oil in- Veffetable ' . dustries. In the manufacture of oils from corn. protein i i. i , , 7 , peanuts, cottonseed, iinseed and cocoanut tliere is by-products ' ,/ ,,,,.,. . ,, . , . lett a press-eake whieli is especially rieli in ])ro- tein. The chief reason why these protein residues have not been seriously considered for human consumjition is their flavor, and the fact that other and more palatable proteins are easily obtain- able. But the ingenuity of the food-chemist and the cook, aided by scarcity of meats and other ])rotein foods, will probably make some of these by-products available for our dietary. Carbohydrate Substitutions The principal carbohydrate foods are flour and bread, the different cereals and breakfast foods, rice and sugar. Until quite recently, none of these food-stuffs had prices that called for a study of substitutions. But just now prices are advanced almost daily, especially on flour and sugar. Here again we liave a blessing in disguise, for it is hoped that the public can be con- vinced of a number of misuses and abuses of these foods. On account of a desire to have otir bread as white as pos- sible and also beeavise of igiiorance in the matter of nutritive values, we discard about one-third of the wheat in milling. And ™^, , this discarded portion includes some of the most , valuable parts of the wheat, partieulai'ly mineral , matter, crude fiber, and no doubt some vitamines. products The fact that the millers were compelled to "bleach" flour with chemicals shows that the public demanded a flour as white as it was possible to make it. For years, food chemists and dietitians have urged a more complete use of wheat 18 for making flour. Wlioh- wheat flour produces a more nutritive bread, a more natural and complete food ; at the same time much more flour is produced from the same amount of wheat. This lesson has been thoroughly learned by European nations during the last year, and now it is our turn. Let us hope the millers will soon receive government instruction as to the amount of flour that will be expected from a bushel of wheat. The substi- tution of whole wheat flour for white or "patent" will be a most important step toward health and economy. While waiting for whole wheat flour to become more popular and better appre- ciated, we are making extensive use of whole wheat products in the form of cereal breakfast foods. Such foods must be classed as the very best because they include all the ingredients put into the wheat-berry by nature; they contain all the mineral matter which plays an important ))art in metabolism ; they con- tain what is lacking in many other breakfast foods, namely, crude fiber — which is an aid to intestinal activity and prevents constipation ; and finally they are never bleached or otherwise chemically treated. By carefully observing the labels on break- fast foods it is a simple matter to pick out whole wheat products. The next step in flour substitution is the use of a mixture of wheat and corn flour. Corn products will probably always be cheaper than wheat products, and these two are of about the ^ f, same nutritive value. The substitution is there- fore physiologically permissible and economically desirable. Corn-flour, and wheat- and corn-flour mixtures are not generally sold as yet, but if present wheat prices continue corn flour will soon become a necessity. Cornmeal and other corn products are already in use ; they are the cheapest and best wheat substitutes we have at present. Nothing need be said here about recipes for using cornmeal since tliey may be found in any cookbook. As soon as potatoes reach their normal price again, they can be used as a substitute for bread or other wheat products. The Bureau of Chemistry at Washington has published the following 19 p recipe developed by Miss H. L. Wessling. It pro- duces a tasty and nourishing bread from potatoes. the quantities of material used making four one-pound loaves. POTATO BREAD — Boil, peel and mash while hot, enough potatoes to make five cups; add two cakes compressed yeast rubbed smootli in four tablespoons of water. Now add three level tablespo(ms of sugar, half as much salt, and a scant cup t)f Hour. Use a half-pint cup. Mix thoroughly by hand. Do not add more water. Let rise until quite light, about two hours. Now add two pounds of flour, knead thoroughly to a very stiff dough. Do not add more water. Let it rise until it is three times its former size, from one to two hours. Now take a little of this dough and press it into the bottom of a straight sided water glass and mark a spot on the glass twice tlie height of the dough. Divide the rest of the dough into four loaves and put into warm greased pans. Set the water glass next to pans and let all rise. When the dough in the glass has doubled in volume, put the loaves into oven and bake for 15 minutes. POTATO BISCUITS— Take 1 cupful mashed potatoes, freshly cooked; 1 cupful flour; 4 teaspoonfvds baking powder; 1/2 teaspoonful salt; 1 tablespoonful butter; 1 tablespoonful lard; V^ cupful milk. Sift the dry ingredients and add them to the potatoes, mixing with a knife. Now work in the butter and lard and enough milk to make a soft dough. Place dough on floured board and roll lightly to 1/^ inch thickness. Cut out with biscuit cutter, place in well greased pan and bake in hot oven for 15 minutes. Other excellent potato recipes can be found in The Cornell Reading Courses, Feb. 1, 1915. .^ , , Another source of carbohydrates is in some Larbony- , . vegetables, especially beans, peas and lentils. , 1 These were mentioned under substitutes for meat vegetables because of their high protein content, and while primarily used for their protein, they supply at the same time considerable carbohydrate food. 20 A substance which deserves particular mention in this con- nection is glucose. It has been and will be used as a substitute for sugar. Not many years ago it would have been useless to p^ tell people that glucose should be classed as a food. Over-zealous food reformers had convinced the public that glucose was to be shunned like poison. But time has changed this ; unbiased investigations have proven that glucose as now manufactured is a wholesome and pure food material. It is made from cornstarch by a simple chemical process, and consists mainly of the simple sugar dextrose (sometimes also called glucose) and a smaller amount of dextrin and maltose. These ingredients are all easily digested, in fact the dextrose is already in a form ready for absorption. Very few j^eople know glucose in its original condition — a water-white heav}' sirup; but we buy it in various slightly modified forms for table use and for baking, candy making and other purposes. Enormous quantities of it are used by the bakers for sweetening purposes as a substi- tute for sugar; almost all candies, low and high priced, are made largely from glucose; brewers use it, spirit vinegar is made from it. Its principal use, however, is a sweetener in place of the more expensive sugar. It has not replaced sugar to any consid- erable extent in the household cookery, but the prediction is here ventured that the housewife will not be long in adopting glucose for home cooking. As in the case of wheat flour, cane and beet sugars might be classed among the over-refined foods. We demand a certain color or appearance in our food-stuflfs, in utter disregard of „ composition or what must be done to such foods. . Ketchup must be red, butter must be yellow and „ „ J sugar must be snow white ; to produce this effect oi loods , - .,1.1 ,.1 11 .1 m the latter it had to be over-renned, all the natural mineral substances removed from it, and finally "bluing" added to it to disguise the last traces of yellowness. But we are learning the fallacy of such practices. By substituting a less refined sugar we not only get more sugar but a more wholesome article. This obviously is economy. Tlif word "sugar" is here 21 used to iticliulo botli cane and beel siii>ar. The only difference of wliieli I am aware between those two is the wliolesale price, .-, , whicli is a few cents lower for the beet suijar: the Lane and '^ , retailers charge the same price for both, and the beet sugars consumer is absolutely unable to tell the difference between them. Cliemically these sugars haAC the same formula, and scientific research shows that no differnce can be detected in their use. Some housewives and candy makers claim they can tell the difference ; these same people are probably also the ones who tasted the chlorine in our Buffalo drinking water three weeks before the chlorination process started. T, .,, As the very latest additions to our carbohv- rroso millet c i , * i i , , " 1 drate foods should be mentioned the starches or and , flour obtained from proso millet and sorghum. sorghum 0^0 Some of our State experiment stations are con- ducting investigations and preliminary announcements tell us that these products will surely be available and suitable as car- bohydrate foods. Now that flour and wheat products are high priced, rice is being more seriously considered as an addition to our dietary. It is essentially a earbohj^lrate food, similar to wheat and oats Tj. except that it contains less protein. Three kinds of rice are found in our stores, "unpolished", "polished" and "coated". The well informed housewife knows that the polished and coated kind belong to the class of over- refined and adulterated foods. The impolished kind retains most of the original mineral salts and fat and is a more or less com- plete food, while the polished kind must be classed as deficient. Pigeons fed exclusively on unpolished rice seem well nourished, but when fed on polished rice they soon develop a food de- ficiency disease, polyneuritis, and die. Only unpolished rice should be used for human food. To use any other betrays an ignorance in matters of diet. Rice cooking is well described in modern cook books. The January 1, 1914, number of the Cor- nell Reading Courses contains valuable information about rice and recipes for its use. 22 Fat Substitutes ^^'lu•ll thinking of fat foods, butter comes to mind first. We are a nation of butter eaters, and it will be a slow process to educate us to the use of substitutes. The eliief butter substitute -r, on the market now is oleomargarine. Iffnorance BuHer ^ ^ , . as to its eomjiosition and the propaganda of the , . butter interests, aided by laws passed hj legis- lators from rural districts, have prevented a more universal use of butter substitutes. The actual nutritive value as ex})ressed in calories is prac- tically the same for all fats and oils. Oils and softer fats are somewhat more completely and quickly digested than the harder ones. It has been discovered recently that butter contains some unidentified substances which make it a more complete food than some other fats. Experiments indicate that butter and cod-liver oil contain the growth-promoting jsubstanees, while in lard and olive oil they are absent. It is therefore suggested that our diet should always include some butter or other milk products sudi as cream, cheese or milk itself. Man}^ people who find a flavor of butter-substitute objection- able are using a mixture of part butter and part substitute. Of the more palatable substitutes are those containing nut and corn products ; a mixture of two parts of nut-margarine and one part of butter is surely more palatable than many brands of pure but- ter. For cooking purposes other fats have long been used in- stead of butter, but the future will see much more substitution. According to conditions, uses, and cost, the following come under consideration: cottonseed cooking oil, cottonseed oil pi'oducts such as Crisco, peanut oil, the cheaper grades of olive oil, corn oil. Until recently corn oil has had an objectionable flavor, but it can now be had with a most agreeable nutty flavor, somewhat like peanut oil. Just at present the cocoanut oil industry is being- developed and this finely flavored fat should be a d«>siral)le addi- tion to the list. 23 An enormous amount of fat is produced in the fish industry, but so far it has not been possible to make fish oil palatable. It is only a question of time, however, when this problem will be solved and then we shall liave another important source of fat food. As a matter of every day and particularly as a war-time economy^ the housewife is carefully saving the fat from trim- mings, drippings from roasts, bacon fat ; beef, pork, chicken, p, turkey and bacon fats can be mixed ; there is no , . . reason for keeping them separate. Such mix- drippings , r c tures can be used for many culinary purposes, such as shortening and frying. Sanitation Although making rapid progress, we are still quite unpre- pared in food sanitation. As. an example I quote the proposed Buffalo Sanitary Code which has been discussed and modified for nearly a year. Everybody realizes the need of a sanitary code for the other fellow. No matter how perfect in chemical com- jDOsition or palatable and appetizing a food is, if it has not been produced, handled, and prepared in a sanitari/ manner it con- stitutes a menace to health. Foods are easily contaminated; man J' spoil quickly. Much has been said and written on un- sanitary methods in food production and handling; I shall only add that the next great step forward will be a rigid enforcement of a law requiring health and cleanliness in persons who handle foods. 24 COMPOSITION AND CALORIES OF FOODS Apples .
