What Boosts Your Risk?

Several factors can make you more likely to develop high cholesterol:

  • A diet high in saturated fats and cholesterol
  • A family history of high cholesterol
  • Being overweight or obese
  • Getting older

Cholesterol and Gender

Until menopause, women typically have lower total cholesterol levels than men of the same age. They also have higher levels of HDL cholesterol, the good kind. One reason is estrogen: The female sex hormone raises the level of HDL cholesterol. Estrogen production peaks during the childbearing years and drops off during menopause. After age 55, a woman’s risk of developing high cholesterol begins to climb.

Cholesterol and Children


There’s evidence that cholesterol can begin clogging the arteries during childhood, leading to atherosclerosis and heart disease later in life. The American Heart Association recommends kids and teenagers with high cholesterol take steps to bring it down. Ideally, total cholesterol should be below 170 in people ages 2 to 19.

Why High Cholesterol Matters

High cholesterol is one of the major risk factors for coronary artery disease, heart attacks, and strokes. It also appears to boost the risk of Alzheimer’s disease. As we saw earlier, high cholesterol leads to a buildup of plaque that narrows the arteries. This is dangerous because it can restrict blood flow. If the blood supply to a part of the heart or brain is completely cut off, the result is a heart attack or stroke.

Cholesterol Buster: Eat More Fiber

Diet changes offer a powerful way to fight high cholesterol. If you’ve ever wondered why some cereals claim to be heart-healthy, it’s the fiber. The soluble fiber found in many foods helps reduce LDL, the bad cholesterol. Good sources of soluble fiber include whole-grain breads and cereals, oatmeal, fruits, dried fruits, vegetables, and legumes such as kidney beans.

Cholesterol Buster: Know Your Fats


No more than 35% of your daily calories should come from fat. But not all fats are equal. Saturated fats — from animal products and tropical oils — raise LDL cholesterol. Trans fats carry a double-whammy, boosting bad cholesterol, while lowering the good kind. These two bad fats are found in many baked goods, fried foods (doughnuts, fries, chips), stick margarine, and cookies. Unsaturated fats may lower LDL when combined with other healthy diet changes. They’re found in avocados, olive oil, and peanut oil.  

Cholesterol Buster: Smart Protein


Meat and full-fat milk offer plenty of protein, but they are also major sources of cholesterol. You may be able to reduce LDL cholesterol by switching to soy protein, such as tofu, at some meals. Fish is another great choice. Some varieties, like salmon, are rich in omega-3 fatty acids, which can improve cholesterol levels. The American Heart Association recommends eating fish at least twice a week.

Cholesterol Buster: Lose Weight


If you’re overweight, talk to your doctor about beginning a weight loss program. Losing weight can help you reduce levels of triglycerides, LDL, and total cholesterol. Shedding even a few pounds can also boost levels of good cholesterol — it tends to go up one point for every 6 pounds you lose.

Cholesterol Buster: Quit Smoking

Giving up tobacco is tough, but here’s one more reason to try. When you stop smoking, your good cholesterol is likely to improve by as much as 10%. You may be more successful if you combine several smoking cessation strategies. Talk to your doctor about which options are best for you.

Cholesterol Buster: Exercise

If you’re healthy but not very active, starting an aerobic exercise program could increase your good cholesterol by 5% in the first two months. Regular exercise also lowers bad cholesterol. Choose an activity that boosts your heart rate, such as running, swimming, or walking briskly, and aim for at least 30 minutes on most days of the week. It doesn’t have to be 30 continuous minutes; two 15-minute walks works just as well.

Treatment: Medications


If high cholesterol runs in your family, diet and exercise may not be enough to get your numbers where you want them. In that case, medication can give cholesterol levels an extra nudge. Statins are usually the first choice. They block the production of cholesterol in the liver. Other options include cholesterol absorption inhibitors, and  bile acid resins. Your doctor may recommend a combination of these medications.

Treatment: Supplements


Certain dietary supplements may help improve cholesterol levels. These include plant sterols, barley and oats, fiber, and green tea. 

Herbal Remedies

Some studies suggest garlic can knock a few percentage points off total cholesterol. But garlic pills can have side effects and may interact with medications. Other herbs that may reduce cholesterol include:

  • Fenugreek seeds
  • Artichoke leaf extract
  • Yarrow
  • Holy basil

How Low Should You Go?


Many people are able to lower cholesterol levels through a combination of medication and lifestyle changes. But how low is low enough? Recent guidelines do not have a target number. If you have diabetes, are at high risk of developing heart disease, or you already have coronary artery disease, you will probably be put on a drug called a statin to lower your cholesterol.

Can the Damage Be Undone?

It takes years for high cholesterol to clog the arteries with plaque. But there is evidence that atherosclerosis can be reversed, at least to some degree. Dean Ornish, MD, has published several studies showing that a low-fat vegetarian diet, stress management, and moderate exercise can chip away at the build-up inside the coronary arteries. Other research supports the idea that big drops in cholesterol can somewhat help open clogged arteries.
