With the progress of knowledge the needs of the human body have not been forgotten. During the last decade much time has been given by scientists to the study of foods and their dietetic value, and it is a subject which rightfully should demand much consideration from all. I certainly feel that the time is not far distant when a knowledge of the principles of diet will be an essential part of one's education. Then mankind will eat to live, will be able to do better mental and physical work, and disease will be less frequent.

At the earnest solicitation of educators, pupils, and friends, I have been urged to prepare this book, and I trust it may be a help to many who need its aid. It is my wish that it may not only be looked upon as a compilation of tried and tested recipes, but that it may awaken an interest through its condensed scientific knowledge which will lead to deeper thought and broader study of what to eat.
