Cholesterol is a fat-like, waxy substance found in the bloodstream and cells. Cholesterol is made in the body as well as provided by your diet. The proper balance of cholesterol is necessary for good health. Cholesterol aids the body in cell membrane production, the creation of some hormones, and other body functions. However, the wrong type of cholesterol can lead to a stroke, heart disease or a heart attack. There are two types: HDL and LDL. LDL is the bad type of cholesterol because it does not dissolve and must be carried away by the body. HDL is the good cholesterol because it helps carry away LDL, protecting the arteries from too much blockage and reducing the risk of heart attack or stroke.
