Atherosclerosis: a problem in newer public health.
"Keys confidently drew a direct line of causation from fat in the diet to serum cholesterol in the blood to heart disease. In a 1952 presentation at Mt. Sinai in New York, Keys formally introduced this idea, which he called his "diet-heart hypothesis." His graph showed a close correlation between fat intake and death rates from heart disease in six countries."
