Depends if U believe. Eat a well balanced low animal fat diet that is rich in fruits, vegetables, legumes, & monounsaturated or polyunsaturated fats, avoiding transfats & hydrogenated fats. No dietary supplement has been shown to prevent heart disease. Statin drugs have. Repeatedly, worldwide, many studies, in men and women. Niacin and fish oils raise HDL (good) cholesterol but unclear if they change outcome. Be thin!
Ldl. Red yeast rice.
Several:Statin+Zetia. Statin+cholesterol absorption inhibitors best for ldl, Niacin best track record for increasing large-hdl. Ldl is always in nmol/l, best <700, HDL in µmol/l, best largehdl>10. See NMR particle test. (cholesterol is a fat molecule made by every cell & promoted for low test price but not correct issue) food, low sugar/carb, reducing visceral body fat & aggressive exercise also helpful.
