Cholesterol is a waxy substance that the body needs to make hormones and vitamins and build healthy cells. However, having too much of the wrong type of cholesterol is a risk factor for cardiovascular disease.
The two types of cholesterol are low-density lipoprotein (LDL) cholesterol, which doctors consider “bad” cholesterol, and high-density lipoprotein (HDL) cholesterol, which is beneficial (“good”) cholesterol.
Lipoproteins carry cholesterol throughout the body via the bloodstream. As a result, LDL cholesterol can accumulate in the blood vessels, become oxidized, and form dangerous plaques in the arteries.
Diet is one factor that can affect cholesterol levels. Other factors include genetics, medications, and physical activity levels.
