“Ye shall eat the fat of the land.”
— Genesis 45:18
Food and fat in various populations
Why do levels of cholesterol vary in different people? Because of their food! This is the answer from Ancel Keys, stated over and over again in his papers. No alternative explanations are ever mentioned; Keys’s hand never trembles when he writes about the influence of diet on blood cholesterol.
One of his arguments is that the average blood cholesterol is high in countries where people eat lots of high-fat food, especially foods high in animal fat, and low in countries where people eat little fat. And, asserts Keys, if an individual with low cholesterol moves to an area where people’s cholesterol is high, then his cholesterol will also rise.
In 1958 Keys illustrated his idea with a diagram demonstrating the relationship between the amount of fat in the food and the cholesterol level of the blood in various populations (fig. 3A).
