    Food in Health and Disease. ^13 a r t ♦ FOOD IN HEALTH, CHAPTER I. THE NATURE, ORIGIN, AND PURPOSE OF FOOD—CLASSI- FICATION OF FOOD — METABOLISM. All living tilings undergo change. Change is a necessary condition of growth and flOvelopinent, of decay and of repair. Change, changa of snhi^tance, i.s, then, a neces.sajy and constant condition of life and activity. In the living and normally active body there are, theiefore, always changes taking ]ilace, losses pro- ceeding from within, and gains accruing from -with- out to compensate for those losses; otherwise it would cease to be active, it would cease to live. The.se gains from without are derived from what we call Food, and the purpose of food is to supply the living organism, however complex or however simple it may be, with the substances or elements necessary for its growth and repair, and for the production and execution of those forms or modes of energy which we speak of as its functions. A perfect and complete food for any living thin must necessarily comprise all the elements of°which Its tissues and all the solids and fluids of its body are composed. B
