10 Ways to Help Boost Your 'Good' Cholesterol
Here's another way to help cut your risk of heart disease.

At the risk of sounding like a certain 20-something socialite, HDL is hot! Recent advances in research have brought more attention to the blood lipid (or fat) we often call "good" cholesterol.
"Good" cholesterol doesn't refer to the cholesterol we eat in food, but to the high density lipoprotein cholesterol circulating in our blood. It's one of the blood fats measured in the lipid panel blood test doctors perform. And it's the component you want more of, because increasing HDL helps lower your risk of heart disease.
A recent report from an expert panel of the National Cholesterol Education Program (NCEP) notes that although LDL or "bad" cholesterol has gotten most of the attention, there's growing evidence that HDL plays an important role.
Here are a few fast facts about "good" cholesterol from the NCEP panel:
Researchers from the Netherlands who analyzed 60 studies concluded that the ratio of total cholesterol to HDL (in which your total cholesterol number is divided by your HDL number) is a better marker for coronary artery disease than LDL measurement alone.
"Boosting HDL is the next frontier in heart disease prevention," says P.K. Shah, MD, director of cardiology at Cedars-Sinai Medical Center in Los Angeles. Shah says that if the new drugs designed to increase HDL levels prove effective, they could potentially reduce the number of heart attacks and strokes by 80% to 90% -- and save millions of lives. HDL-boosting drugs are now being tested.
>How Does HDL Help?
Experts aren't yet sure exactly how HDL cholesterol helps reduce the risk of heart disease. But a few possibilities have emerged.
The NCEP says that high HDL levels appear to protect against the formation of plaques in the artery walls (a process called atherogenesis), according to studies in animals.
Lab studies, meanwhile, suggest that HDL promotes the removal of cholesterol from cells found in abnormal tissues, or lesions, in the arteries.
"Recent studies indicate that the antioxidant and anti-inflammatory properties of HDL also inhibit atherogenesis," says the NCEP report.
10 Ways to Increase Good Cholesterol
What many people don't know is that some diet and lifestyle changes may help to increase "good" cholesterol levels.
Here are some of the contenders:
1. Orange Juice. Drinking three cups of orange juice a day increased HDL levels by 21% over three weeks, according to a small British study (at 330 calories, that's quite a nutritional commitment). This study could be highlighting an effect from high-antioxidant fruits and vegetables. Stay tuned in the years to come.
2. Niacin. There is some evidence niacin (vitamin B3) helps increase HDL. Michael Poon, MD, chief of cardiology at the Cabrini Medical Center in New York, says people with low HDL levels might benefit from taking 500 milligrams of niacin each day, building up to 1,000 milligrams a day. But he warns that supplemental niacin "can have some side effects and is not for everybody, particularly for people who already have high HDL levels. "He says anyone taking niacin supplements should be monitored by a doctor. Short of supplements, many foods contain niacin as well. Here are a few:
