Why You Eat Food.

Nine-tenths of our food is eaten to supply heat and energy. The amount of heat and energy required by individuals Is reckoned in calories. The most accurate way to determine how much food to buy for a family, is to figure how many calories the members require, says a writer in the Woman’s Home Companion. Tables of food values with directions for using them are, published by both national and state agricultural departments. There are also simple textbooks that explain clearly the usefulness of reckoning by calories. These books are readily understood after a little study of them. When one knows approximately how 'many calories each member of the family requires, and how many calories .certain amounts of food contain, one can settle with definite figures the old question that used to be answered by guesswork only: “How much shall I buy?"
