Ways to reduce cholesterol? generally healthy, and not overweight but have high cholesterol. also have slight sinus bradycardia/sinus arrhythmia. doctors have told me not to worry after repeated ekgs. i want to keep my heart healthy/avoid chf later?

Rhythm,lipids: The sinus mechanisms are a normal healthy heart,long term the lower the LDL & higher the HDL the more likely you will live longer;currently high potency statins may be a good bet in addition to regular exercise;lean body mass and & good hygiene

Mostly genetic: A very high cholesterol may need to be medicated now, if for example you have familial hypercholesterolemia with LDL over 200. It is fairly common and deadly. Exercise is actually more helpful than diet here and you want to maintain lifelong good habits. There are guidelines, and there's no reason to believe super-tight cholesterol control in youth benefits you decades later.
