The History of Dietetics: Man is what he eats

"Man is what he eats" is a German proverb, the propriety of which may be chiefly alliterative, though the apothegm of our greatest English physician goes even further: "If we could solve the problem of diet," Dr. Radcliffe tells us, "it would almost amount to the rediscovery of paradise. Wrong eating and drinking, and the breathing of vitiated air (which is gaseous food), these form the triple fountain-head of nearly all our diseases and our misery." - F.L. Oswald
