With special regard to the requirements of the people in these days of rising prices, especially of meats, the United States Department of Agriculture has issued a booklet, prepared by C.F. Langworthy, Ph.D., and Caroline L. Hunt, A.B., experts in nutrition connected with the Department, which gives authoritative information about the cheaper cuts of meat and the preparation of inexpensive meat dishes. This has become generally known as "The Government Cook Book." By the permission of the Department we here present portions of the information it contains, together with those recipes which best illustrate the principles of meat cookery for the home table. VALUE OF MEAT AS FOOD Considering the fact that meat forms such an important part of the diet, and the further fact that the price of meat, as of other foods, has advanced in recent years, it is natural for housekeepers to seek more economical methods of preparing meat for the table, and to turn their thoughts toward the less expensive cuts and ask what economy is involved in their use, how they may be prepared, and whether the less expensive dishes are as nutritious and as thoroughly and easily digested as the costlier ones. The value of meat as food depends chiefly on the presence of two classes of nutrients, (1) protein or nitrogenous compounds, and (2) fat. The mineral matter it contains, particularly the phosphorus compounds, is also of much importance, though it is small in quantity. Protein is essential for the construction and maintenance of the body, and both protein and fat yield energy for muscular power and for keeping up the temperature of the body. Fat is especially important as a source of energy. It is possible to combine the fat and protein of animal foods so as to meet the requirements of the body with such materials only, and this is done in the Arctic regions, where vegetable food is lacking; but in general it is considered that diet is better and more wholesome when, in addition to animal foods, such as meat, which is rich in proteins and fats, it contains vegetable foods, which are richest in sugar, starch, and other carbohydrates. Both animal and vegetable foods supply the mineral substances which are essential to body growth and development. The difference between the various cuts of meat consists chiefly in amount of fat and consequently in the fuel value to the body. So far as the proteins are concerned, i.e., the substances which build and repair the important tissues of the body, very little difference is found.
