The Natural Food of Man

<p>There can be no doubt that whatever other function food may or may not have it replaces broken-down tissue. The tissue-wastes of the preceding day are replenished by the food eaten; so the body remains about the same in weight no matter how much exercise be taken or how much tissue is broken down. These tissues are very complex in their nature and a variety of food is consequently necessary to restore the tissues destroyed-food containing a number of elements (the counterpart of the elements destroyed) being necessary to offset the waste. Proteid fats carbohydrates and various salts are therefore necessary in the food; and no food that does not contain these constituents in larger or smaller quantities can be used by the body or can be classed as a true food. - Hereward Carrington</p>
