Cholesterol

Cholesterol is a fat-like substance that the body needs for many important functions. It is a building block of cell membranes, a precursor for hormones such as estrogen and testosterone, and for the production of bile acids. Some is absorbed through food, but the majority is produced in the liver.

Too high cholesterol levels can lead to deposits in the vessel walls and increase the risk of cardiovascular diseases. However, a balanced level is important, as cholesterol is also indispensable for health.
