Why is high-density lipoprotein (HDL) important?

High-density lipoprotein (HDL) is often referred to as "good cholesterol" due to its crucial role in cardiovascular health. The primary reason it is important is its function in helping to remove low-density lipoprotein (LDL), commonly known as "bad cholesterol," from the bloodstream. HDL facilitates the transport of LDL from the arteries back to the liver, where it can be metabolized and excreted. This process is vital for preventing cholesterol build-up in the arteries, which can lead to atherosclerosis and increase the risk of heart disease and stroke.

In addition to its cholesterol removal properties, HDL also possesses anti-inflammatory and antioxidant effects, which contribute further to heart health. By lowering the levels of LDL and helping maintain a healthier cholesterol balance, HDL plays a protective role against cardiovascular diseases.
