HDL cholesterol, Part II
How to get more of a good thing
Doctors call it high-density lipoprotein cholesterol, but most people know it as the "good" cholesterol. By any name, HDL cholesterol protects the heart and circulation. For years, scientists have attributed its benefit to the scavenger effect, or reverse cholesterol transport. Indeed, HDL can remove harmful LDL ("bad") cholesterol deposits from the walls of vulnerable arteries, then deliver the LDL to the liver for disposal from the body. But research shows that HDL is even better than we thought. In addition to its LDL removal function, it has protective antioxidant, anti-inflammatory, and anticlotting properties. It also improves endothelial function, allowing arteries to widen when tissues need more oxygen-rich blood.
