In terms of health, what does HDL cholesterol help with?

High-density lipoprotein (HDL) cholesterol is often referred to as "good cholesterol" due to its protective role in cardiovascular health. It helps decrease the risk of heart disease by transporting cholesterol away from the arteries and back to the liver, where it can be processed and eliminated from the body. This function is crucial because it aids in preventing the buildup of plaque in the arterial walls, a condition known as atherosclerosis, which can lead to heart attacks and strokes. Thus, having higher levels of HDL cholesterol is generally associated with a lower risk for cardiovascular problems, making it a key factor in maintaining heart health.
