To produce heat, and to liberate muscular and mental energy. Every particle of body substance is constantly changing. The new material for cells and tissues, the substance to supply the energy needed in the metabolic work of tearing down and rebuilding, the energy used in the digestive process of converting the food into condition to be assimilated, and the energy used in muscular, brain, and nerve movement must all be supplied by food. Every effort of the brain in the process of thinking, every motion, and every muscular movement requires energy which the food must supply. The body is composed of a vast number of cells varying according to the tissue or organ in which they are found. The characteristic of all living matter is that it constantly reproduces itself. Cells perform their appointed work, wear out, and must be replaced by new ones or derangements follow. The new cells constantly being formed, increase in size and in so doing push the worn-out, dying, and dead cells out of the way. The process of building and eliminating continues within the body and on its surface every instant of life.
