This book details the experimental trials of feeding isolated food substances to white rats conducted by the author and their colleagues in the early 20th century. The feeding of isolated food substances had been employed by other scientists to determine the role of specific proteins in nutrition. However, most of these investigations had been brief and had shown no definitive results. The author's experiments were unique in their duration and the variety of proteins used. The author begins by discussing the concept of the protein minimum, the smallest amount of protein an animal needs to maintain its nitrogen equilibrium. They then describe their experimental methods, which involved feeding rats a diet of purified protein, starch, lard, and inorganic salts. They varied the type of protein in the diet and measured the rats' weight, food intake, and nitrogen balance with the aim to determine which proteins were most effective in supporting growth and preventing weight loss. The author found that casein, the protein found in milk, was the most effective protein for supporting growth and preventing weight loss in rats. They also found that the addition of certain inorganic salts to the diet was essential for maintaining nitrogen balance. The experiments demonstrated that proteins are not all equivalent in their nutritional value and that the composition of the diet can have a significant impact on an animal's health. The book concludes with a discussion of the implications of these findings for human nutrition.
