Cholesterol is the major cause of heart disease
Cholesterol levels are important, but the best predictor of heart problem is high blood pressure. Blood pressure can tear holes in your arteries. The way the body repairs the hole is to fill it with cholesterol. If it's healthy cholesterol you get a nice smooth lining, but if you've got cholesterol that's sort of rotten, now the body has to heal that. The body heals cuts by putting scabs on them and that scab quickly builds on top of this and blocks off the artery. And that blocked artery can cause a heart attack.
