Cholesterol is a waxy, fat-like substance made in the liver and other cells and found in certain foods, such as food from animals, like dairy products, eggs, and meat. The body needs some cholesterol in order to function properly. Its cell walls, or membranes, need cholesterol in order to produce hormones, vitamin D, and the bile acids that help to digest fat. But the body needs only a limited amount of cholesterol to meet its needs. When too much is present health problems such as heart disease may develop.
Types of Cholesterol
The three main types of cholesterol complexes used to transport cholesterol include:
- Low density lipoproteins (LDL): LDL, also called “bad” cholesterol, can cause buildup of plaque on the walls of arteries. The more LDL there is in the blood, the greater the risk of heart disease.
- High density lipoproteins (HDL): HDL, also called “good” cholesterol, helps the body get rid of bad cholesterol in the blood. The higher the level of HDL cholesterol, the better. If levels of HDL are low, the risk of heart disease increases.
- Very low density lipoproteins (VLDL): VLDL is similar to LDL cholesterol in that it contains mostly fat and not much protein.
