Cholesterol levels in the body actually have very little to do with daily cholesterol intake. Poor cholesterol levels is the result of inflammation in the body, mainly from sugar and refined carbs. Certain foods that are naturally high in cholesterol like eggs are actually super good for you.
The best thing you can do to lower cholesterol levels is to follow a cholesterol friendly diet - low in saturated fats and refined sugars, and high in omega 3 fatty acids -
and to regularly incorporate hard cardio that really gets your heart rate up into your training program.
A good overall cholesterol support supplement certainly won't hurt either. Check out N2guard from n2bm.com. N2guard contains 43 ingredients designed to detox the body and keep cholesterol levels optimal.
