Almost all can allow enough time for meals to eat slowly. Coarse and raw foods are always to be had and are usually cheaper than the conventional soft, concentrated cooked foods. In fact, meat, eggs, and like foods are among the most expensive and the least desirable. If we compare the cost of flour and of the other cheapest food materials, with the cost of oysters, one of the dearest, we find that the latter is fifty times as expensive as the former for the same food value. This takes no account, of course, of the expenses involved in cooking either of them. It has been proved by actual experience that one can live in the best of health on food costing as low as ten cents a day, exclusive of the labor of preparing, cooking and serving. Mrs. Richards, in her "Cost of Food," says that this is possible anywhere in America within fifty miles of a railroad. The only real objection to living on this minimum expense is the lack of variety. The following is a brief list of foods in ascending order of cost per 100 calories of food value, the cheapest being at the beginning and the dearest at the end: glucose, corn-meal, wheat-flour, oatmeal, cane-sugar, salt pork, rice, wheat bread, oleomargarine, beans, peas, potatoes, butter, milk, cheese, beef-stew, ham, mutton-chops, beef, eggs, and oysters. If the foods in this list be looked up in the table given in the SUPPLEMENTARY NOTES for their protein, fat, and carbohydrate contents, it will be seen that a well-balanced ration is possible without the use of expensive foods. In fact, among the cheap foods are some consisting mostly of protein, some consisting mostly of fat, and some consisting mostly of carbohydrate. For instance, cheap sources of protein are skim milk, beans, cheese, and peanuts. Cheap sources of fat are oleomargarine and cottonseed-oil. Cheap sources of carbohydrate, i.e., starch and sugar, are bread, bananas, potatoes, glucose, and even ordinary sugar. If a diet, selected for cheapness, is not at first well balanced, a judicious admixture of one or more of the foods just mentioned, will restore equilibrium. A cheap bulky food is cabbage.
