We want our lives to count for something. Failure is, to a certain extent, a disgrace. And to live the life, of achievement you need energy, enthusiasm, ambition. You must have strength, vitality, endurance. And the buoyant spirits that make play of all work. If all this is valuable, then the power behind the man or the woman, in the form of food, assumes great importance. Day by day our bodies are evolved from the food we eat. We are what we are, because of food. We are hardy, vigorous and capable or devitalized and incompetent, depending largely upon the quality of nourishment that we furnish ourselves day by day. There never was a time in the history of the world when the human diet was worse than it is at the present day.
