Concerned About Your Cholesterol? 10 Ways to Lower LDL and Raise HDL

Your doctor tells you that your level of LDL—the “bad” type of cholesterol—is too high, and, in a double whammy, he says that your level of HDL—the “good” cholesterol—is too low. So, you wonder, is there anything you can do to decrease the bad while increasing the good?

There are steps you can take to accomplish this. It’s much easier to push LDL down than to push HDL up, but it’s well worth the effort to strive to do both. A November study published in the Postgraduate Medical Journal found that increasing HDL levels in patients who are also aggressively lowering their LDL levels can reduce cardiovascular risk.

An HDL level of 60 milligrams per deciliter or higher is believed to help protect against heart disease. Women’s risk for heart disease rises significantly at HDL levels below 47 mg/dL; men are at particular risk if their HDL level falls below 37 mg/dL.

For LDL, a reading of 190 mg/dL or higher is considered to be very high, 160 to 189 is considered to be high, and 130 to 159 is considered to be borderline high. A level of 100 to 129 is considered to be near optimal; less than 100 is considered optimal for most people. But for those who are at very high risk for heart disease or have a history of heart trouble, a reading of less than 70 is preferred.

Raise HDL - Lower LDL

Depending on your cholesterol levels, successfully reaching your target levels will probably take a combination of medication and lifestyle and dietary changes. Among the changes you’ll have to make: Stop smoking, work out, lose weight, and eat well, the PMJ study suggests.

If you’re up to the task, here are 10 ways to lower your LDL and raise your HDL:

  1. Taking a statin can lower LDL by 10 percent (at the lowest dose) to 55 percent (at the highest dose), says Robert H. Eckel, professor of medicine at the University of Colorado-Denver and past president of the American Heart Association. A small percentage of people who take statins experience severe myopathy, which is muscle discomfort or weakness. (Consider 7 reasons statin users shouldn’t dismiss muscle pain.) Statins also bump up HDL, typically by 5 to 10 percent (that’s only 2 to 4 mg/dL, not enough to make much of a difference). Other types of cholesterol-lowering medications are sometimes prescribed in combination with statins.
  2. A cholesterol absorption inhibitor would be a likely next step for those who can’t take statins because of side effects, Eckel says. There is only one such drug—ezetimibe (Zetia). A 2003 study in the journal Pharmacotherapy found that when given alone or in combination with other cholesterol-lowering medications, ezetimibe reduced LDL by 15 to 20 percent and raised HDL, but, as with a statin, not by much—2.5 to 5 percent.
  3. Bile acid sequestrants can decrease LDL by about 10 to 20 percent, according to the National Heart, Lung, and Blood Institute. When combined with a statin, these medications can lower LDL by more than 40 percent. Medications in this class—cholestyramine, colestipol, and colesevelam—come in pill or powder form. The powder must be mixed with water or juice before being taken. These drugs offer an added benefit for diabetics: Recent research has shown they help to lower blood glucose levels.
  4. Nicotinic acid, also known as niacin, is a water-soluble B vitamin that lowers LDL by 10 to 20 percent and is the only drug that can have a real impact on HDL, says Eckel. According to the NHLBI, it can lift HDL levels by 15 to 35 percent. A study published this month in Current Medical Research and Opinion says that niacin and fibrates (explained below) are underutilized—either alone or in combination with statins—to treat low HDL and high triglycerides (a kind of fat in the blood). Because most people who take niacin experience flushing of the skin and a warm feeling, particularly on the face, neck, and ears, up to half of those taking the medication choose to stop it, according to the Mayo Clinic.
  5. Fibrates are mostly effective at lowering triglycerides and in heightening HDL levels, according to NHLBI. These drugs usually lower LDL by 10 to 20 percent, Eckel says. For those who take this type of medication, HDL increases are usually in the neighborhood of a modest 10 to 15 percent.
  6. Lose weight. This can lower LDL, though levels will go back up unless you make lasting dietary changes, Eckel says. Aim to lose 10 percent or more of your body weight. Keep in mind that while you’re losing weight, your HDL levels may fall, Eckel warns. But as you maintain your new body weight, your HDL will increase as long as you’ve lost at least 10 percent of your body weight. Try U.S. News’s 10-week workout routine to help you get started, and avoid these 7 mistaken beliefs that can prevent weight loss.Exercise itself can raise HDL, although usually not by a meaningful amount. “For sedentary people with low HDL cholesterol and heart disease, even a little bit of exercise can raise it—but not by a lot,” Eckel says. “For the average Susan or Joe, moderate aerobic activity needs to be accompanied by a change in body composition—less fat—to increase HDL.” There are a few caveats: Women who have abnormal menstrual periods have minimal increases in HDL, and too much resistance training may actually lower HDL cholesterol if not accompanied by some aerobic training.
  7. Limit saturated fats. Eating saturated fats—which are the main diet-linked cause of high cholesterol – tends to raise your HDL, but it also increases your LDL. These fats are mostly found in animal foods such as beef, lamb, poultry, pork, butter, cream, and milk, and in coconut and coconut oil, palm and palm kernel oil, and cocoa butter. “We think the bad cholesterol is more of a concern than the good cholesterol,” says Eckel, so it’s important to limit consumption of saturated fats. The American Heart Association recommends limiting saturated fat intake to less than 7 percent of your total daily calories. “A reduction in saturated fats by a moderate amount will reduce LDL,” Eckel says.
  8. Avoid trans fats, which have been purged from many prepared foods but are found in small quantities in some animal products. They also are formed during the hydrogenation process of making margarine, shortening, and cooking oils. Trans fats can increase LDL and decrease HDL. Vegetable oils that are partially hydrogenated are the source of about 75 percent of trans fatty acids in the American diet, according to the AHA. It’s easier now to find foods that contain little to no trans fats, as more attention is paid to how trans fats affect people’s health. Many restaurants are making an effort, and New York City and California have banned trans fats.As a rule, try to limit your intake of trans fats to less than 1 percent of your total calories on any given day, the AHA suggests. Read the nutrition facts label when you buy food to keep an eye on how much trans fat you’re consuming. “Look at the ingredients, and if ingredients say hydrogenated or partially hydrogenated, there are trans fats in there,” says Barry Franklin, director of cardiac rehabilitation at the William Beaumont Hospital in Royal Oak, Mich.
  9. Have an occasional drink. Drinking alcohol increases HDL levels slightly but doesn’t decrease LDL, according to NHLBI. Because drinking too much alcohol can result in alcoholism, damage to the liver and the heart muscles, high blood pressure, and high triglyceride levels, among other problems, it’s important to limit consumption. Men and women who consume alcohol should do so in moderation, which means one to two drinks daily for men and one drink for women, the AHA suggests.
  10. Quit smoking. There are plenty of reasons to stop, but one that’s not widely known is that smoking has been shown to decrease HDL levels. Smoking also makes it harder to work out, which means it is less likely you’ll reach healthful cholesterol goals. And that’s not all. Consider these other reasons why you should stop smoking right now.
