ARE FRUITS AND VEGETABLES LUXURIES?
In the house of diet fruits and vegetables may be likened to windows and doors, fire-places and chimneys; we could dispense with them, we could board up our windows and make a fire on a big stone in the middle of the room, letting the smoke escape through a hole in the roof, but such a course would not mean comfort year in and year out. So we may exist without fruits and vegetables, but it is worth while to stop and consider what we gain by their use.
We shall have to admit at the outset that if we have to spend money or labor for them, fruits and vegetables are not the cheapest source of fuel for the human machine. Some of them are cheaper fuel than b.u.t.ter, eggs, or meat, but not as cheap as cereals, sugar, mola.s.ses, syrups, and some of our cheapest fats. This is true of potatoes, parsnips, carrots, dried peas and beans, and such fruits as bananas, prunes, raisins, dates, figs, and possibly a few other dried fruits, but we cannot justify our investment in most fruits and vegetables solely on the plea that they are "filling" in the sense of being of high fuel value; on this ground lettuce, celery, cabbage, tomatoes, lemons, rhubarb, cranberries, and many others would find no place in our domestic economy.
Remembering that man does not live by fuel alone, we may find ample reasons for spending some of our food money upon things which at first thought seem to give an inadequate return. There is an old adage, "An apple a day keeps the doctor away," which if true means that the apple is a real economy, a kind of health insurance, for an apple costs seldom over five cents--often only one--and a doctor"s visit may easily cost a hundred times as much. There is a certain amount of truth in the saying, though the apple does not have a monopoly of the supposed virtue. It is more accurate, if less poetic, to say that an _a.s.sortment_ of fruits and vegetables helps to keep us in good health. Before the days of modern "cold pack" canning, mothers used to a.s.semble their little home groups in the spring and, in spite of sundry hidings under tables on the part of reluctant Johnnies and Susies, dutifully portion out herb tea or sulphur in mola.s.ses. Spring cleaning could never stop short of "cleansing the blood!" And after a monotonous winter of salt pork and fried potatoes no doubt heroic measures were necessary to make up for an ill-chosen diet.
Nowadays we recognize no such seasonal need. We carry our surplus of fruits and vegetables over from summer to winter and profit not only in the greater daily pleasure of our tables but in clearer skins, brighter eyes, and less "spring fever."
How do fruits and vegetables help to keep us well? In the first place, by their wholesome effect upon the bowels. As a rule we a.s.sociate regular daily movements with health, but do not always recognize the part which diet plays in securing them. If we eat little besides meat and potatoes, bread, b.u.t.ter, and cake or pie, we are very likely to have constipation.
This is particularly true for those who work indoors or sit much of the time. Now, fruits and vegetables have several properties which help to make them laxative. Many have considerable woody fiber. In celery and asparagus we find it in actual "strings"; in cabbage, spinach, lettuce, and other stem or leaf vegetables it may not be so noticeable, but it is certainly present and we should realize that it is useful. The skins of fruit are of this nature and may often be eaten, as in case of prunes, figs, apples, dried peaches and apricots. The outer coats of grains, which serve the same purpose, are frequently removed by milling, but similar coats of peas and beans are not so removed except in the case of dried split peas. In the juices of fruits and vegetables we find a variety of laxative substances. This explains why apple juice (sweet cider), orange juice or diluted lemon juice may be a very desirable morning drink. The effect is partly due to the acid but not wholly. Juices which are not acid to the taste, as those of prunes, figs, onions, have laxative properties.
So from a great variety of fruits and vegetables, especially those which are fibrous or acid or both, we may obtain the subst.i.tute for "pills" in wholesome foods which are generally cheaper than drugs.
No diet can be properly built without a suitable supply of mineral salts.
The free use of milk is our greatest safeguard against lack of any save iron, but when milk is scarce and has to be saved as now for the babies of the world, it is fortunate that we can make fruits and vegetables take its place in part. Some of our very common vegetables are good sources of the calcium (lime) and phosphorus so freely supplied in milk. Among these may be taken as an example the carrot, which has not had due recognition in many quarters and in some is even spoken of contemptuously as "cattle food." Its cheapness comes from the fact that it is easy to grow and easy to keep through the winter and should not blind us to its merits. A good-sized carrot (weight one-fourth pound) will have only about half the fuel value of a medium-sized potato, but nearly ten times as much calcium as the potato and about one-third more phosphorus. While actual figures show that other vegetables, especially parsnips, turnips, celery, cauliflower, and lettuce, are richer in calcium than the carrot, its cheapness and fuel value make it worthy of emphasis. Everyone who has a garden should devote some s.p.a.ce to this pretty and palatable vegetable. It is perhaps at its best when steamed till soft without salting and then cut up into a nicely seasoned white sauce; its sweetness will not then be destroyed nor its salts lost in the cooking water. It is not only useful as a hot vegetable, but in salads, in the form of a toothsome marmalade, and as the foundation of a steamed pudding. For little children it is most wholesome and they should make its acquaintance by the time they are a year and a half old, in the form of a cream soup. A dish of carrots and peas (one-half cup peas, one-fourth cup carrot cubes, one-half cup white sauce) will have almost the same food values (for fuel, calcium, phosphorus, and iron) as an equivalent serving of oatmeal, milk, and sugar (three-fourths cup cooked oatmeal, one-half cup milk, one rounding teaspoon sugar) and will add variety to the diet without costing a great deal more unless one pays a fancy price for peas.
Even when meat and eggs are not prohibitive in price, fruit and green vegetables are an important source of iron in the diet. And when war conditions make the free consumption of meat unpatriotic, it is rea.s.suring to think that we really can get along without meat very well if we know how. Two ounces of lean beef will furnish no more iron than a quarter of a cup of cooked spinach or half a cup of cooked string beans or dried beans, or one-sixth of a cup of raisins, or half a dozen good-sized prunes.
Cabbage, peas, lettuce, dandelion greens, beet tops, turnip tops and other "greens" are well worth including in our bill of fare for their iron alone. By the time children are a year old we begin to introduce special iron-bearing foods into their diet to supplement milk. Aside from egg yolk, we give preference for this purpose to green vegetable juice or pulp, especially from peas and spinach or a mixture of both. The substantial character of dry beans is too well known to require comment, but how many realize that they are a most valuable source of iron and other mineral salts? The fact that they are not a "complete diet" in themselves should not disturb anyone who realizes that all diets are built from a variety of foods. We are hardly likely to use beans to the exclusion of everything else except in dire necessity, and then what better could we do than use freely a food which will go so far toward sustaining life at so small a cost?
There is a further significance for fruits and vegetables in their contribution to the diet of the growth-promoting, health-protecting vitamines. That the presence of fruits and vegetables in the diet is a safeguard against scurvy is well known, though the full scientific explanation is not yet ours. That the leaf vegetables (spinach, lettuce, cabbage, and the like) contain both the vitamines which are essential to growth in the young and to the maintenance of health in the adult seems a.s.sured, and gives us further justification for emphasis on green vegetables in the diet of little children, when properly administered--i.e., always cooked, put through a fine sieve, and fed in small quant.i.ties.
Aside from being valuable for regulation of the bowels, for mineral salts, and vitamines, to say nothing of more or less fuel value, fruits and vegetables give zest to the diet. The pleasant acidity of many fruits, their delicate aroma, their beautiful form and coloring, the ease of preparing them for the table, are qualities for which we may legitimately prize them, though we may not spend money for them until actual nutritive requirements are met. Dr. Simon Patten, in his _New Basis for Civilisation_, ably expresses the value of appetizers: "Tomatoes, the hothouse delicacy of the Civil War time, are doing now what many a b.l.o.o.d.y revolution failed to accomplish; they have relieved the monotony of the salt pork and boiled potatoes upon the poor man"s table. The clear acid flavor of the canned vegetable lightens ugly heaviness and adds tonic gratifications for the lack of which men have let each other"s blood."
As already remarked, those who have plenty of highly flavored meat are apt to be satisfied by it or to demand stronger flavors (coffee, catsup, pickles, and tobacco) than those found in fruits and vegetables. They are also apt to spend so much money on meat that they have none left to buy what seem to them unimportant items in the diet, and to have a much less wholesome diet than they might have for the same money. Studies of expenditures in many families show that a good rule to insure a well balanced diet is to spend no more money for meat than one does for fruit and vegetables. Also, it is well to remember that vegetables are usually cheaper than fruits and that dried ones may largely take the place of canned or fresh ones. For wholesome and economical living, have fruit of some kind at least once a day and make the main dish of one meal a vegetable dish whenever possible. Thick cream soups, souffles, creamed or scalloped vegetables, are all substantial and appetizing. The way to learn to like such foods is to keep trying. One may learn contentment with the proverbial dinner of herbs more easily by realizing that one is building valuable bricks into the house of diet; and in the present emergency one may, by selection of fruits and vegetables of high energy value, save less perishable foods for our soldiers and allies. The knowledge that a banana is equivalent in calories to a large slice of bread or a small pat of b.u.t.ter becomes tremendously significant; that an apple, an orange, four prunes, four dates, or a cup of peas, may not only take the place of bread but actually add something which the bread does not contain, means that we may be the gainers from our own sacrifices, without embarra.s.sment thereat.
We shall have reaped a speedy reward for doing our duty.
CHAPTER VI
FATS AND VITAMINES
In the days of the ancient Romans vegetable oils were prized for food and b.u.t.ter was used for cosmetics. In America today we are asking what is to become of us if we cannot have b.u.t.ter to eat! Such are the fashions in food. "June b.u.t.ter" is one of our gastronomic traditions. The sample in the restaurant may have none of the firm creamy texture and delicate aromatic flavor of the product of the old spring house; but as long as it is labeled b.u.t.ter we try to bring our sensations into line with our imaginations. For the real b.u.t.ter flavor there is no more a subst.i.tute than there is for the aroma of coffee. But these are matters of esthetic pleasure rather than of nutrition. They depend largely upon habit. Whale blubber and seal oil are as much appreciated in some quarters as b.u.t.ter is by us. An American going inland from the Atlantic coast is often surprised to find that olive oil, instead, of being served on every table, is exceedingly disliked.
For the sustenance of the body we must recognize that fat is fat, whatever its flavor. A calorie from b.u.t.ter yields neither more nor less energy than a calorie from lard or bacon, olive oil or cottonseed oil. The common food fats are all very well digested if judiciously used--not in too large quant.i.ties, nor over-heated in cooking, and not "cooked into" things too much as in pastries, rich sauces, and fried foods. Whether we spread our bread with b.u.t.ter or beef drippings amounts to the same thing in the long run; the main point is which we are willing to eat.
A change is rapidly coming over our food habits. The price of b.u.t.ter has been soaring beyond our reach, and the market for "b.u.t.terine," "nut margarine," "oleomargarine," or whatever the subst.i.tute table fat may be called, has expanded tremendously. It is excellent household economy to buy milk and a b.u.t.ter subst.i.tute rather than cream or b.u.t.ter. In these subst.i.tutes refined vegetable oils such as cottonseed, cocoanut, and peanut, and oils derived from beef or lard are so combined or treated as to produce the desired hardness, and churned with milk or milk and b.u.t.ter to improve texture and flavor. Lard subst.i.tutes are similarly made from one or more of these fats, but are harder in texture and no attempt is made to give them a b.u.t.ter flavor by churning with milk. All the fats used are wholesome and efficient sources of energy for the human machine.
In the absence of b.u.t.ter some other form of fat is desirable in the diet, because fat is so concentrated a food. There is a limit to the capacity of the human stomach to hold food. People who live on a diet largely of rice, which has almost no fat in its make-up, develop characteristically distended abdomens, because they have to eat such a great quant.i.ty of food to get fuel enough for their day"s work. When people are for any reason put on a milk diet for a considerable time it is customary to put something into the milk to make it more concentrated, for otherwise they would drink and drink and then hardly get fuel enough. To give a concrete ill.u.s.tration--a man"s energy requirement for a day may be met by from four to five quarts of milk (unless he is doing very heavy manual labor), but it would be much more practical to subst.i.tute a loaf of bread, which is comparatively dry, for one quart of milk, and three ounces of fat (six tablespoonfuls) for another quart of milk, making the total volume but little over half what it would be if four quarts of milk were taken. For people who are engaged in hard physical toil, fat is exceedingly important for this purpose of gaining in concentration. "Fat is fuel for fighters,"
and it is perfectly reasonable to ask those who are not doing much heavy labor to eat other kinds of food and save fat for those who simply have to have it to do their work well. In the ordinary mixed diet one can easily dispense with an ounce of fat (two tablespoonfuls). Each tablespoonful is equalled in energy by an apple, or a banana, a large egg, two half-inch slices of bread about three inches square, four dates, four prunes--and it is no great strain on one"s capacity for food to subst.i.tute such items for the fat.
On account of its concentration, fat is good for transportation; and aside from its energy value it gives the diet "staying" qualities. Other things being equal, one feels hungry sooner after a meal without fat than after one in which it is liberally supplied. People doing manual labor, and especially out of doors, feel the pangs of hunger more than sedentary folks and hence need more fat to keep them comfortable. No man can do his best work when all the time thinking how hungry he is. It behooves us all then, as good citizens, to recognize the greater need of our soldiers and sailors and our hard-working laborers for as liberal allowances of fat as we can make. At the same time, we cannot for our own best health dispense with fat altogether. We may consider anything up to two ounces apiece a day legitimate for our own maintenance of efficiency.
In departing from food customs there is a natural timidity lest the new food shall in some way be less healthful than the old. Recent scientific researches have revealed a hitherto unsuspected property in b.u.t.ter, a discovery which has aroused some concern as to whether we can safely subst.i.tute other fats for it. Young animals fed on a diet of highly purified food materials in which lard is the only kind of fat may seem fairly well but do not grow normally, while those fed the same diet in every respect except that the lard is replaced by b.u.t.ter grow as young animals should and are more resistant to disease. Study of other food fats shows that they may be divided into two groups, one with this growth promoting property and one without it. In general, the vegetable oils do not have it, while b.u.t.ter and beef oil do; on the other hand, lard does not have it, while the oil from corn does. Careful a.n.a.lysis of the situation has shown that a fat-soluble vitamine is present which can in the laboratory be separated from the fat. This same vitamine is present in a variety of food materials--in whole milk, in egg yolks, in leaves of plants--but we have not studied it long enough to know just how much spinach we can subst.i.tute for a tablespoonful of b.u.t.ter so far as the vitamine is concerned. We must await further investigations. But we may rest a.s.sured that with a fairly liberal amount of milk and some green vegetables, possibly some beef fat, we need not fear any disastrous consequences from the subst.i.tution of some other fat for b.u.t.ter. Where the diet is limited and the entire quant.i.ty of fat is not very large, it seems prudent to select oleomargarine made largely from beef oil and, where circ.u.mstances permit its use without the sacrifice of any other dietary essential, to use b.u.t.ter in the diet of growing children unless they get a full quart of milk apiece a day.
Changing our food customs is difficult because it means also changing our cooking customs. But many dishes can be made with less fat than we are accustomed to put in or with different kinds from those we have hitherto preferred. Often the fat from frying is left in the pan to be washed out and thrown away. If every cook could say to herself, "Every two drops of fat make a calorie and every calorie counts in the world today," it might seem more worth while to hold the pan a minute and drain out the fat for further use. A thousand calories mean a day"s life to a baby. It is always more wholesome to cook foods so that they are not coated with fat, and one may get brown products in a frying pan without more than a thin film of fat to keep the food from sticking. It is well to remember in this connection that the unsalted lard subst.i.tutes are more satisfactory than the saltier fat foods, in which there may be a trace of milk.
The thought that fat is fuel wherever we find it in food will stiffen our resolution to take a little pains with the fats which we have been wont to discard. Anyone can get from the Department of Agriculture suggestions for the practical use of chicken, mutton, beef, and other kinds of meat fats.
The main points are to free them from flavor, by melting them with milk or water, possibly using some special absorbent like potato or charcoal too, and then mixing hard and soft together, just as the oleomargarine-makers do, to get such a degree of hardness as suits one"s purpose. All this requires time and thought. Let no one dream that the patriotic duties of the kitchen are trivial. Anything that is worth while costs something; money, thought, labor--perhaps all three. To salvage kitchen fat may not be economical in time and labor (though it generally is more so than one might think), but there is more time and labor than food available today.
So it seems the "bit" of the housekeeper to set a standard for her family as to the amount of fat she will purchase per week, which is at least one-fourth lower than their ordinary consumption, and to depend upon special conservation of what may have gone to waste hitherto for any increase in this allowance.
CHAPTER VII
"SUGAR AND SPICE AND EVERYTHING NICE"
"Do come and taste how nice the burnt pig eats!" So cried the miscreant son of Hati when his attempt to rescue his father"s live-stock from utter destruction resulted (at least according to Lamb) in adding one more delicacy to the table of civilized man. That the "burnt pig" commended itself instantly to the taste of other men is attested by the recklessness with which they ignited their own houses to secure the new sensation again.
Not all flavors make an immediate appeal. Many persons can mark the time when they learned to like olives, or tomatoes, or tea. The taste for some foods was acquired so early that there is no consciousness of any time when they were not enjoyed, and the impression prevails that the liking for such foods is instinctive. Sometimes that is the case, but quite as often not. Children have to be taught by patient repet.i.tion to like most of the common foods which make the staples of the diet, and likings thus acquired are as strong as those which seem more natural.
However taste be accounted for, we have to recognize the fact that food is chosen for flavor more than for ultimate benefit. It is one thing to say that oatmeal is more nutritious than bread and coffee; it is quite another to induce a man to give up the latter for the former! And yet the distinguishing characteristic of man is that he can subjugate his immediate impulses for his future benefit, or find a course that will harmonize the two--take coffee with his oatmeal for instance, or find some way to flavor it, perhaps with sugar.
Probably no one flavor is so universally enjoyed as sweetness. "Sweeter than the honey in the honey comb" is an ancient symbol of appreciation.
When the sugar bowl is empty how many things lose zest! Tea, coffee, cocoa, breakfast cereals, fruit, might still be acceptable, but cake, pie, and ice cream are unthinkable without sweetness; the soda fountain, the bakery, and the candy shop bear further testimony to our love of sweets.
Four million tons of sugar a year for the American people--eighty-five pounds apiece, nearly a quarter of a pound apiece daily--this is no inconsiderable amount of flavoring!
But is not sugar good food? Most a.s.suredly. Three lumps of sugar would furnish the extra energy needed to walk a mile; a quarter of a pound represents about one-sixth of a man"s daily fuel requirement. But one baked potato would furnish the same energy as the three lumps of sugar; a quarter of a pound of cornstarch would supply the same fuel as the quarter pound of sugar. Nutritionally starch and sugar are interchangeable, the advantage as far as digestion is concerned being with the starch rather than the sugar. And yet we put sugar on starch! So much for instinct being a guide to scientific food combinations!
The problem of doing without sugar is primarily a problem of flavor--a problem of finding something else which is sweet. Hence we turn our cornstarch into glucose (make corn syrup, for example) outside the body instead of inside it, so that we can taste the sweetness as it goes down.
The main trouble with this kind of sugar is that it is not sweet enough to satisfy us and we are apt to use too much, thus endangering our digestions by sheer concentration of what would be, in smaller quant.i.ties, most wholesome. Once more we see that nutrition is largely a question of _how much_; how much glucose or other sugar our stomachs can stand we find out by experience; few stomachs can stand when empty the quant.i.ty represented by a lollipop, and yet we frequently see children allowed to suck these between meals. The same amount of sugar diluted with water, as in a gla.s.s of lemonade, would do less harm; it might be combined with flour in a cooky with more impunity; better yet, it might be made a part of a whole meal, taking it in several dishes (sauce, dessert, etc.), or, if we must have it as candy, at the end of the meal. Used in this way, the advantages of sugar as a food may be had with relatively little disadvantage.
Honey, "the distilled sweetness of the flower," commands a price commensurate with the exquisiteness of its production, but is not quite as easy of digestion as some other forms of sugar. Because of its intense sweetness it may be combined with advantage with less sweet syrups, such as corn syrup. The cook estimates that by measure it will take one and a half times as much corn syrup as cane sugar to get the customary effects in sweet dishes. By using one part of honey to three of corn syrup a sweeter product is obtained, which is free from several of the disadvantages of honey in cookery.
Maple syrup and sugar are not only prized for their sweetness, due to the presence of ordinary cane sugar, but for the delicate "maple" flavor so difficult to duplicate. Nutritionally a tablespoon of maple sugar is equivalent in fuel value to about four-fifths of a tablespoon of cane sugar, while equal volumes of cane mola.s.ses, corn syrup, and maple syrup are interchangeable as fuel, though not of equal sweetening power.
Mola.s.ses is a less one-sided food than cane sugar or corn syrup. The latter furnish nothing but fuel, and if used too freely not only disturb digestion but tend to crowd out foods which yield mineral salts. Mola.s.ses is quite rich in calcium, one tablespoonful yielding as much as five ounces of milk, and is for this reason a better sweet for growing children than ordinary sugar or corn syrup when the amount of milk which they can have is limited, or when fruits and vegetables are hard to get. Mola.s.ses ginger snaps make, therefore, an excellent sweet for children, much better than candy, but of course to be eaten only at meal time.
The aim of good home cooking should be to please the family with what they ought to eat. The chef in a big hotel may have to prove the superiority of his art over that of a rival chef, and vie with him in novelty and elaboration, but the home cooking may be ever so simple provided the result is a happy, well-nourished family. A chocolate layer cake that takes two hours out of a day is no more nourishing than the same materials served as poached eggs, bread and b.u.t.ter, and a cup of chocolate. It is worth while to train a family to enjoy the flavor of simply prepared foods, and to realize that the food is the thing which counts and not the way it is dressed up. On the other hand, if one has to use a few food materials over and over, as one must in many places when the money that can be spent for food is very little, it is by slight changes in their form and flavor that one keeps them from palling on the appet.i.te. If one has to use beans every day, it is a good thing to know a dozen different ways of preparing beans. One may have the plain bean flavor, properly toned up by a suitable amount of salt; the added flavor of onions, of tomatoes, of fat pork, of mola.s.ses, or a combination of two or three. One may have plain oatmeal for breakfast (the flavor developed by thorough cooking, at least three or four hours in a double boiler or over night in a fireless cooker); oatmeal flavored with apples in a pudding for dinner; or oatmeal flavored with onions and tomatoes in a soup for supper; the same food but quite different impressions on the palate.
Herbs and spices have from time immemorial given flavor to man"s diet.
"Leeks and garlic," "anise and c.u.min," "salt and pepper," "curry and bean cheese," are built into the very life of a people. The more variety of natural foods we have the less dependent we are upon such things. Our modern cooks, confronted in the present crisis with restrictions in the number of foods which they may use, may find in bay leaves, nutmeg, allspice, and all their kind, ways of making acceptable the cereals which make a diet economical, the peas and beans which replace at least a part of the meat, and dried fruits and vegetables which save transportation of fresh or canned goods.
Tea and coffee are both flavors and stimulants. They are used literally by thousands to give flavor to bread or rice. Dependence on a single flavor is apt to result in a desire to have it stronger and stronger, and hence less and less wholesome. This is a good reason for some variety of flavor; better tea one meal and coffee another than the same one all the time. Too freely used, and made too strong, tea and coffee may have a bad effect upon the nervous as well as the digestive system. They should never be given to children. It is better for adults to get their flavor from something without such effects. Because the combination of bread and coffee tastes good, one may be deceived into thinking himself well nourished on a diet consisting of little else. And yet this is a very inadequate diet for anybody, and disastrous to the normal development of children. One must be on guard, then, lest one"s desire for flavor be satisfied without the body"s real needs being met.
The wise cook saves her best flavors for the foods which would be least acceptable without them and does not add them to foods which are good enough by themselves. The latter course marks the insidious beginning of luxury. "Once give your family luxuries and you are lost as far as satisfying them economically is concerned," remarked a clever housewife.
"Even a rat will not taste bread when bacon is nigh," observed a sage physiologist. The demand for flavor grows and grows with pampering, till nothing but humming-birds" tongues and miniature geese floating in a sea of aspic jelly will satisfy the palate of him who eats solely for flavor--who never knows the sauce of hunger, or the deliciousness of a plain crust of bread. We must be on guard, saying, like the little daughter of a cla.s.sical professor, "If Scylla doesn"t get me Charybdis will." Flavor we must have, but not too much, not too many kinds at once, and not applied indiscriminately to foods which need them and foods which do not. The wise cook uses her arts to secure the proper nourishment of the family and not for her fame as "a good cook."
CHAPTER VIII
ON BEING ECONOMICAL AND PATRIOTIC AT THE SAME TIME
