Ancel Keys death Died 20 Nov 2004 at age 100 (born 26 Jan 1904).
American nutritionist and epidemiologist who was the first to identify the role of saturated fats in causing heart disease. In 1935, he studied the physiological effects of altitude, which he conducted in the Andes. At the onset of WW II, he designed the lightweight yet nutritious K ration used by American paratroops. The hard biscuits, dry sausage, hard candy and chocolate it contained were items he originally selected at a Minneapolis grocery store, and the ration was named with his initial. In 1947, he began a decade of study of 283 local businessmen. From its results, he determined that saturated fat chiefly determined blood cholesterol levels, and linked smoking, high blood pressure and elevated cholesterol with heart attacks.
