Cholesterol is a waxy, fat-like substance that is used by the human body to build and maintain cell membranes and produce certain hormones. Cholesterol is naturally produced by the body and is commonly found in animal products such as meat, poultry, fish, dairy and eggs. Although a small amount of cholesterol is essential for life, in excess, it is associated with atherosclerosis – narrowing and hardening of the arteries. As a result, excess cholesterol can lead to heart disease and stroke. 

The Dietary Guidelines for Americans recommends that healthy individuals limit their intake of cholesterol from food to no more than 300 mg per day. The major dietary sources of cholesterol include cheese, egg yolks, beef, pork, poultry, and shrimp. It is also important to limit saturated fat and trans fat consumption since these nutrients raise blood cholesterol levels.

A low cholesterol diet can help improve blood cholesterol levels. However, because other factors, including genetics, can affect cholesterol levels, individuals with high cholesterol should discuss strategies for lowering cholesterol with their doctor or other healthcare professional.
