What is the nickname for high density lipoprotein (HDL) due to its role in heart health?

High density lipoprotein (HDL) is often referred to as "good cholesterol" because of its crucial role in promoting heart health. HDL functions primarily by transporting excess cholesterol from the bloodstream and tissues back to the liver, where it can be metabolized and removed from the body. This process helps reduce the overall levels of cholesterol in the blood, particularly harmful low density lipoprotein (LDL) cholesterol, which is associated with an increased risk of cardiovascular diseases.

The protective effects of HDL include its ability to prevent the build-up of plaques in the arteries, thereby reducing the risk of atherosclerosis, heart attacks, and strokes. Higher levels of HDL are associated with a lower risk of heart disease, leading to its designation as "good cholesterol." This nickname reflects its beneficial influence on cardiovascular health, distinguishing it from LDL, which is referred to as "bad cholesterol" due to its association with cardiovascular problems.
