Food and fibre
1978
General facts about fiber and its role in man's health are presented. Fiber is simply plant cell walls. Since fiber dilutes calories and makes them harder to get, keeps the teeth clean and intact, and renders the stools soft, there is at least a case for the theory that fiber-depleted (refined) foods are intrinsically damaging to health. The desired effects of fiber are almost impossible to define numerically. If a man decides to take all his plant foods in unrefined form, nature itself will regulate fiber intake.
