Cholesterol OverviewCholesterol is a soft, fat-like, waxy substance that is found in the blood stream and all of your body’s cells. It is an important part of a healthy body, since it is used for producing cell membranes, hormones, and needed to complete other bodily functions. The cholesterol in our bodies is either ingested in the foods we eat or is produced by our own bodies. 75 percent of blood cholesterol is produced by the liver. Too much cholesterol in the blood, however, is a serious risk factor for coronary heart disease and stroke. The medical term for high levels of blood cholesterol is called hypercholesterolemia. The body produces two types of cholesterol: LDL cholesterol and HDL cholesterol.
