[Sidenote: Card-playing]
Card-playing and similar games afford wholesome mental recreation for some persons. However, they, too, are liable to be associated with late hours, and other disadvantages even when they do not degenerate into gambling. Card-playing, dancing, and many other popular forms of amusement often border on dissipation.
[Sidenote: Suicidal Amusement]
Amusements which weaken and degrade are not hygienic.

A chief and common error of diet consists, then, in using too much protein. Instead of 10 calories out of every 100, many people in America use something like 20 to 30. That is, they use more than double what is known to be ample. This excessive proportion of protein is usually due to the extensive use of meat and eggs, although precisely the same dietetic error is sometimes committed by the excessive use of other high-protein foods such as fish, shell-fish, fowl, cheese, peas and beans, or even, in exceptional cases, by the use of foods less high in protein when combined with the absence of any foods very low in protein. The idea of reducing the protein in our diet is still new to most people.
Prof. Rubner of Berlin, one of the worldโs foremost students of hygiene, said, in a paper on โThe Nutrition of the People,โ read before the recent International Congress on Hygiene and Demography:
โIt is a fact that the diet of the well-to-do is not in itself physiologically justified; it is not even healthful. For, on account of false notions of the strengthening effect of meat, too much meat is used by young and old, and by children, and this is harmful. But this meat is publicly sanctioned; it is found in all hotels; it has become international and has supplanted, almost everywhere, the characteristic local culinary art. It has also been adopted in countries where the European culinary art was unknown. Long ago the medical profession started an opposition to the exaggerated meat diet, long before the vegetarian propaganda was started. It was maintained that flour foods, vegetables, and fruits should be eaten in place of the overlarge quantities of meat.โ
When protein is taken in great excess of the bodyโs needs, as is usually the case in the diet of Americans, added work is given the liver and kidneys, and their โfactor of safetyโ may be exceeded.
Flesh foodโfish, shell-fish, meat, fowlโwhen used in great abundance, are subject to additional objections. They tend to produce an excess of acids, are very prone to putrefaction, and contain โpurinsโ which lead to the production of uric acid. This is especially true of sweetbreads, liver and kidney. The well-known deficiency in flesh foods of lime often needs to be taken into consideration in the dietary. Some of the vegetable foods, such as peas and beans, rich in protein, are likewise not free from objection. Their protein is not always easily digested and is, therefore, likewise liable to putrefaction. Unlike most vegetable foods, they contain some purins. These foods are, however, rich in iron, which renders them a more valuable source of protein for children and anemic people than meat. Also, an excess of protein is not so likely to be derived from such bulky foods as from meat, which is a concentrated form of protein.
We have spoken thus far only of the needed proportion of protein. The remainder of the diet, say 90 per cent. of the calories, may be divided according to personal preference between fats and carbohydrates in almost any proportion, provided some amount of each is used. A good proportion is 30 per cent. fat and 60 per cent. carbohydrate.
Section IIIโHard, Bulky, and Uncooked FoodsThe wise choice of foods does not consist entirely in balancing the ration as to protein, fat, and carbohydrate.
Hard foods, that is, foods that resist the pressure of the teeth, like crusts, toast, hard biscuits or crackers, hard fruits, fibrous vegetables and nuts, are an extremely important feature of a hygienic diet. Hard foods require chewing. This exercises and so preserves the teeth, and insures the flow of saliva and gastric juice. If the food is not only hard, but also dry, it still further invites the flow of saliva. Stale and crusty bread is preferable to soft fresh bread and rolls on which so many people insist. The Igorots of the Philippines have perfect teeth so long as they live on hard, coarse foods. But civilization ruins their teeth when they change to our soft foods.
Most of the ordinary foods lack bulk; they are too concentrated. For this purpose it is found that we need daily, at the very least, an ounce of cellulose, or โwoody fiber.โ This is contained in largest measure in fibrous fruits and vegetablesโlettuce, celery, spinach, asparagus, cabbage, cauliflower, corn, beets, onions, parsnips, squash, pumpkins, tomatoes, cucumbers, berries, etc.
Until recently would-be food reformers have made the mistake of seeking to secure concentrated dietaries, especially for army rations. It was this tendency that caused Kipling to say, โcompressed vegetables and meat biscuits may be nourishing, but what Tommy Atkins needs is bulk in his inside.โ
Cooking is an important art; but some foods when cooked lose certain small components called vitamins, which are also found in the skin or coating of grains, especially rice, also in yolk of egg, raw milk, fresh fruit, and fresh vegetables, especially peas and beans. These vitamins are very important to the well-being of the body. Their absence is probably responsible for certain diseases, such as beriberi, scurvy, and possibly pellagra, as well as much ill health of a less definite sort. Some raw or uncooked foods, therefore, such as lettuce or tomatoes, celery, fruits, nuts, and milk, should be used in order to supply these minute and as yet not well-understood substances which are destroyed by the prolonged cooking at the temperature which is employed in order to sterilize canned foods. They are also diminished and often destroyed by ordinary cooking, except in acid fruits and acid vegetables.
It is true that only very clean milk is entirely safe in an absolutely raw state, and that heat is usually needed to kill the germs. But this heat, even at the comparatively low temperature of pasteurization, has been found to destroy the vitamins that prevent scurvy. Orange juice should always be given to infants over one month old who are fed pasteurized milk.
Not all foods can be taken raw with advantage. Most starchy foods, such as cereals and potatoes and unripe fruit must, of course, be cooked in order to be made fit to eat.
Raw foods have dangers of their own in carrying germs and parasites, and it is extremely advisable that all raw foods should be very thoroughly washed before eating.
In addition to protein, fat, carbohydrate, and vitamins, there are other elements which the body requires to maintain chemical equilibrium, and for the proper maintenance of organic functions. These are the fruit and vegetable acids and inorganic salts, especially lime, phosphorus, and iron. These substances are usually supplied, in ample amounts, in a mixed diet, containing a variety of fruits and vegetables and an adequate amount of milk and cream. Potatoes, feared by some in acid condition (such as gout), are actually valuable because of their alkalinity.
Section IVโThorough MasticationWhether it be from lack of hard foods, requiring prolonged chewing, or from the nervous hurry of modern life, or from other causes, it is undoubtedly a fact that most people in America eat too rapidly. The correction of this habit will go far toward reforming an individualโs diet in every way.
Thorough mastication means masticating up to the point of involuntary swallowing. It does not mean forcibly holding the food in the mouth, counting the chews, or otherwise making a bore of eating. It merely means giving up the habit of forcing food down, and applies to all foods, even to liquid foods, which should be sipped.
The consequences and evils of insufficient mastication are many, and may be enumerated as follows: Insufficient use of the teeth and jaws (and hence dental decay as well as other and worse dental evils); insufficient saliva mixed with the food (and hence imperfect digestion of the starchy substances); insufficient subdivision of food by mastication (and hence slow digestion); the failure of the taste nerves to telegraph ahead, as it were, to the stomach and other digestive organs an intimation of the kind and amount of digestive juices required (and hence indigestion); the overseasoning of food to make it relishable even when bolted (and hence overeating and irritation of the mucous lining); the excessive use of meat and eggs and like foods, which can be eaten rapidly with relative impunity, and the corresponding neglect of other foods, like bread, grains, vegetables, and salads, which require more mastication (and hence intestinal poisoning).
The habit of insufficient mastication is subtle, because it has become โsecond natureโ with most of us. To free ourselves of it we must first of all allow plenty of time for our meals and rid our minds of the thought of hurry. A boyโs school in which the principal is endeavoring to fight the habit of food-bolting has wisely ordained that no boy may leave the dining-room until a certain hour, even if he has finished eating long before. In this way the boy soon learns that there is nothing to be gained by fast eating, and, in fact, that the pleasantest way of spending the meal-time is to prolong the relish of the food. It would be well if all of us would adopt a similar rule for ourselves. Mr. Gladstone did something of the sort and was noted for the slow mastication of his food. Latterly Mr. Horace Fletcher set such a rule for himself, and revived the interest of the public in the subject.
At first one must give some conscious attention to his efforts to reform; but if one will merely attend carefully to the first three mouthfuls of a meal, the slow pace can often be established for the rest of the meal without further thought.
Slow eating is important not merely as a matter of mastication, but also as a matter of taste and enjoyment. Food must have a pleasing taste and flavor and then must be enjoyed in order to be most readily assimilated.
There is a mistaken notion that the hygiene of food means โgiving up all the things that taste good.โ While it is true that, in many cases, sacrifices have to be made, the net result of reforming oneโs diet is not to diminish but to increase the enjoyment of food. In general, it is extremely unhygienic to eat foods which are not relished. Experiments by Pavlov and others have shown that the taste and enjoyment of food stimulate the flow of digestive juices.
Finally, slow eating is a great aid in the proper choice of foods. Some suggestions have already been given as to the wise choice of foods, but no rules can be formulated which will completely insure such a choice. Even the wisest physiologist can not depend altogether on his knowledge of food values, while, to the layman, the problem is so complicated that his main reliance must be on his own instincts. Animals depend exclusively on instinct except when under domestication. Civilized man should not and can not altogether depend upon instinct, but his food instincts are far more keen and correct if he obeys the rule of eating slowly than if he bolts his food.
In the choice of foods it is as difficult to distinguish absolutely between what are โgoodโ
