Preface from the author: America has just passed through a great financial crisis-one of the many which occur from time to time, because of badly adjusted financial conditions, and as the result of greed-and we hear much talk of "hard times," and the lack of money wherewith to buy the necessities of life. Now, I believe that such "hard times," and such conditions, could be largely averted if only the people were taught to live correctly: taught how to economise their food, and how to take care of their bodies. There can be no doubt but that much of the waste which occurs throughout the land is due to ignorance of the great laws of life and health; and if people were only taught how to reduce their food-supply scientifically-and not to expend so much money on their bodies, and especially on their food-there would be but a small amount of suffering compared with that which has existed in the past. Teach the public how to preserve the body in a state of health, upon a small amount of money, and we shall have solved one of the greatest economic factors confronting us to-day. I believe that this may be brought about, in a large part at least, by adopting the principles of nutrition outlined in this book; and I submit it to the public largely with that idea in mind. But that is only part of my object, none the less. My desire is to help humanity to secure better health-to teach them how to live cheaply and economically; above all, how to live so as to preserve the highest standard of health, strength and energy. We should thus have a cleaner, a hardier and a happier race of individuals; and I firmly believe that all true reform-social economic religious-must come primarily through the body-i.e. these reforms can only be effected by first of all reforming the body, and its habits; and when that has been rendered clean and pure, the coveted mental and moral reforms will be found to follow of themselves. External conditions and environment may count for much, but the internal factor counts for much more. The internal personality of the man is what we should aim to reach first of all; and this can be reached most easily and effectually by means if the body-for in that he is most wrapped; with its feelings and emotions he is most closely connected. Reform the inner man, and particularly his body, and trust to man to reform his environment. Make men and women what they ought to be, and they will soon reform their external conditions.I have attempted to deal, in this volume, with the quality of foods, as I dealt with their quantity, in my former book. In this way, the ground will have been pretty thoroughly covered, from the particular point of view from which I have attacked these problems. I can only hope that, as the result of these two volumes, many persons may find health and a long life, who would otherwise have sunk into a premature grave. If I could feel that I had in any way helped to accomplish this, I should be more than satisfied.
