These people can usually reduce plasma cholesterol by following careful diets. Your liver makes approximately 700 to 900 mg cholesterol daily. Cholesterol, being a lipid, does not mix with water. In order to travel through the blood, a watery system, cholesterol is coated with protein. The resulting macro-molecule is a lipoprotein.
Lipoproteins are carriers for transporting cholesterol throughout the body.
Five major classes of lipoproteins have been identified. LDL-cholesterol is generally on its way to be deposited in tissues, including the artery wall. High levels of LDL-cholesterol are associated with increased health risks. The table below shows the risk category for various levels of LDL-cholesterol. HDL-cholesterol is probably on its way out of the body pool of cholesterol.
