According to Ravnskov's book, serum cholesterol is not a good predictor of CHD. Neither is LDL. In the Framingham study, in men over 47, lower cholesterol was linked with a higher likelihood of death, and vice versa. Overall the correlation between cholesterol and CHD was 0.36, which is very weak. (1.0 is a perfect correlation.)

In the 1960s the famed heart surgeon Michael DeBakey found that a large number of people with CHD had normal cholesterol.

There is also evidence that cholesterol protects against stroke.
