High-Density Lipoprotein (HDL) is commonly referred to as "good" cholesterol because it plays a beneficial role in cardiovascular health. HDL is responsible for transporting cholesterol away from the arteries and back to the liver, where it can be processed and removed from the body. This process helps to reduce the risk of atherosclerosis, which is the buildup of cholesterol and other substances in the artery walls that can lead to heart disease.

Higher levels of HDL cholesterol are associated with a lower risk of heart disease, as it helps to clear excess cholesterol from the bloodstream. This protective effect is why HDL is often termed "good" cholesterol. In contrast, other types of lipoproteins, such as Low-Density Lipoprotein (LDL), are referred to as "bad" cholesterol, as elevated levels can lead to the accumulation of cholesterol in the arteries, increasing the risk of heart-related issues.
