Cholesterol comes in "good" and "bad" types. Blood cholesterol lipoprotein is white and waxy. Low-density lipoprotein (LDL) is known as "bad" cholesterol because it can easily damage the inner lining of blood vessels. The other type, high-density lipoprotein (HDL), is called "good" cholesterol because it removes the former from the artery walls. The benefit of good cholesterol is that it transports cholesterol from cells outside the liver to the liver for metabolism. The metabolized products are then excreted from the body through the gastrointestinal tract via bowel movements. Therefore, good cholesterol acts like a scavenger in the blood; the higher its level, the more cholesterol the body can eliminate. At the same time, good cholesterol has antioxidant and anti-inflammatory effects on blood vessels, protecting them and reducing damage. Eating more of the following foods can help increase good cholesterol levels.
