These data, however, must be supplemented by the observations made in our own country, which have been very extensive, through the “investigations on the nutrition of man in the United States,” carried on by the Office of Experiment Stations in the Department of Agriculture, under the efficient leadership of Atwater. As stated by Messrs. Langworthy and Milner, in an official bulletin issued in 1904, dietary studies of the actual food consumption of people of different classes in different parts of the United States have been made during the years 1894 to 1904 on about 15,000 persons,--men, women, and children,--as a result of which it is indicated that “the actual food requirements of persons under different conditions of life and work” vary from 100 to 175 grams of proteid per day, with a total fuel value ranging from 2700 to 5500 calories. For comparison, the various data may be tabulated as shown on page 155.
