Definition: Cholesterol is a fat-like material that is found in all the cells of the body. Cholesterol is a necessary part of the body to create hormones, vitamin D, and substances that assist in food digestion.
Examples: There are two types of cholesterol packages (lipoproteins) in the body: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). LDL cholesterol is what people sometimes refer to as “bad” cholesterol. Having too high of LDL levels leads to backup in the arteries. HDL is what is sometime referred to as “good” cholesterol. HDL carries cholesterol from other parts of the body to the liver for removal from the body.
