Excerpt from Principles of Nutrition and Nutritive Value of Food
Sir: I have the honor to transmit herewith an article on Principles of Nutrition and Nutritive Value of Food, by Prof. W. O. Atwater, special agent in charge of nutrition investigations, prepared in accordance with instructions given by the Director of this Office. For a number of years the Department has carried on studies regarding the kinds and amounts of foods consumed by persons of different occupations and with different incomes, the composition of food, the relative cost of nutrients when furnished by different foods, and many more technical questions. The present bulletin discusses the general principles of nutrition, as well as a number of the more important phases of the subject, with special reference to the results obtained in Department investigations and the closely related work of the agricultural experiment stations. As the work has progressed the earlier ideas have been modified, and the present bulletin is designed to supplement and replace earlier Department publications by the author having a similar scope. In preparing this bulletin Professor Atwater has had the assistance of Miss Helen W. Atwater.
The first edition of this bulletin was published several years ago. In preparing this edition for publication a number of changes which seemed desirable have been made.
It is believed that the article is a useful summary of available information on the subject, and its publication as a Farmers' Bulletin is therefore recommended.
