Ancel Keys (1904–2004), nutrition researcher
During World War II, Keyes developed K-rations, which are named for him. During the 1950s, he undertook a comparative study of different national diets and health statistics, concluding that fat consumption was a causative factor in heart disease. His work initiated both a long medical debate on the effects of various dietary fats and a tremendous concomitant expansion of commercial food products with purported cardiac benefits.
