About Cholesterol

As cholesterol (plaque) builds up in the arteries, the arteries begin to narrow, which lessens or blocks the flow of blood.
Blood cholesterol is a waxy, fat-like substance made by your liver. Blood cholesterol is essential for good health. Your body needs it to perform important jobs, such as making hormones and digesting fatty foods.
Your body makes all the blood cholesterol it needs, which is why experts recommend that people eat as little dietary cholesterol as possible while on a healthy eating plan.
Dietary cholesterol is found in animal foods, including meat, seafood, poultry, eggs, and dairy products. Learn more about preventing high cholesterol by making healthy eating choices.
Strong evidence shows that eating patterns that include less dietary cholesterol are associated with reduced risk of cardiovascular disease, but your overall risk depends on many factors. Learn what raises your risk for high cholesterol.
