Can My HDL Level Be Too High?

High-density lipoprotein (HDL) is a type of cholesterol that is often called "good" cholesterol. HDL is often contrasted with its low-density counterpart, LDL, which is labeled "bad" cholesterol.

Function

• In your body, HDL carries the excess cholesterol to the liver from the arteries, but if it accumulates in the arteries, it can cause narrowing and hardening. It could also increase the chance of blockages and blood clots.

Benefits

• Increased HDL levels promote heart health and reduce the risk of heart disease. An increased HDL has qualities that are antioxidant, anti-inflammatory and anti-clotting.

Levels

• The National Cholesterol Education Program classifies an HDL level below 40 mg/dL as "low" while a level of 60 mg/dL or above is considered "high."

Diet

• To increase HDL, the Mayo Clinic recommends a diet with heart-healthy elements including soluble fibers like oats, polyunsaturated fatty acids from nuts, omega-3 fatty acids, like those found in fish and olive oil.

Blood Test

• The U.S. National Cholesterol Education Program recommends that every person who is older than age 20 should get a test for cholesterol levels, preferably a lipoprotein profile blood test.
