That the quantity and quality of food for man, and the times for taking it, should be regulated in harmony with the physiologic laws governing the processes of digestion, assimilation, nutrition, disintegration and excretion, is too obvious to the intelligent physician to require argument or illustration.
The fact that all living animal structures are constantly undergoing disintegration atom by atom or cell by cell, renders it necessary that there should be constantly present in the fluids permeating the structures, new atoms or cells or vitalized materials, ready to take the place of materials lost, and thereby maintain the integrity of the tissues.
During childhood or youth, or period of growth, the amount of food assimilated must exceed the amount lost by disintegration or there would be no progressive development of the various parts of the body. But in adult life the amount of true food or ingests each day should
