> If you have normal cholesterol though - we have long known that people with normal cholesterol also have heart attacks.
Just to continue on this line, we also know that people with a genetic disposition for low cholesterol have a significantly lower risk of coronary heart disease than people with ostensibly normal cholesterol levels. It is one of the most proven, obvious correlations (more cholesterol increases the incident of CHD) in medicine.
Some snake-oil merchants, usually pitching a book or supplement, have often tried to muddy the waters by pointing out that someone at death's door often has very low cholesterol (they usually aren't eating, and cancer often "eats" cholesterol and leads to low levels), trying to then extrapolate this out.
