Medicine does not supply the material which sustains life

"Food has been defined as a substance which, when
introduced into the body, supplies material which
renews some structure or maintains some vital process.
Medicine modifies some vital action, but does not
supply the material which sustains such action. A
supply of suitable food is therefore essential during
the medical treatment of disease ; for medicine alone
will not, and is not designed to, sustain life. Neither,
on the other hand, will changes of food so modify
vital action when it is disordered as to render the

administration of medicine superfluous. Nevertheless
it must be allowed that diet does play an important
part in promoting recovery from disease, and that
some kinds of food do stimulate vital action in a
degree far beyond the actual amount of nutritive
material they supply. "
