In adopting a raw food diet, or in reducing heat-giving elements, such as artificial sugars and hot drinks, it is important to apply more external heat to the body for a while, or else have the morning meal served in a sunny room. Plenty of outdoor exercise is necessary to properly utilize a vegetarian diet.

In the preparation of this volume I have been assisted by several friends who are interested in the publication of such a work.

It is my hope that this book will be instrumental in reducing the high cost of living as well as in lessening women’s work and worry.

CHAPTER I.
“THE BLOOD IS THE LIFE.”

Its Structure and Function Depend on the Building Material.

Foods are substances which, when introduced into the system, supply the necessary material for growth, renewal and maintenance of the vital structures. Food is anything that nourishes.

Foods must contain the same elements found in our bodies. The body requires a combination of different food elements in proper proportion to produce a suitable diet. Foods are divided into five classes: water, protein, fats, carbohydrates and mineral matters.

Air and sun are also foods, but are not generally spoken of as nutrient.
