Cholesterol is a waxy substance that occurs naturally in all parts of the body.
Your body needs cholesterol, which it uses to make many hormones and vitamin D. Cholesterol is to make bile acids, which help the body digest the fats you eat. Your body makes enough cholesterol to meet its needs. You can also get cholestrol from the foods you eat. Only foods from an animal source such as meat, poultry, fish and dairy foods contain cholesterol. When there is too much cholesterol in your blood, the excess can become trapped in the walls of your arteries.
