Rich in omega-3 fatty acids and all-around delicious, walnuts have also been shown to improve the HDL-to-total cholesterol ratio, according to a study published in the American Diabetes Association’s peer-reviewed journal, Diabetes Care. This ratio is used by physicians to assess overall cardiovascular risk and can provide more information than just one value alone. A desirable ratio is anything below 5:1, but a ratio of 3.5:1 indicates very minimal cardiovascular risk.

Coronary heart disease: What you need to know The coronary arteries supply oxygen and blood to the heart. They can narrow, often because cholesterol accumulates on the arteries’ walls. This results in coronary heart disease, the most common type of heart disease in the U.S. Here, learn about risk factors, early warning signs, means of prevention, and treatments. Read now
Paying close attention to what you eat can help you reduce your risk of developing atherosclerosis. Atherosclerosis is the narrowing of arteries caused by plaque build-up inside the arteries. As the arteries narrow, blood can't flow properly through the arteries. Theis can lead to a heart attack or stroke. If the artery-clogging process has already begun, you may be able to slow it down by making changes in your lifestyle, including your diet.
There is some research suggesting that artichoke leaf extract (Cynara scolymnus) may help to lower cholesterol. Artichoke leaf extract may work by limiting the synthesis of cholesterol in the body. Artichokes also contain a compound called cynarine, believed to increase bile production in the liver and speed the flow of bile from the gallbladder, both of which may increase cholesterol excretion.
Aside from the inconvenience of taking niacin, two recent, highly-anticipated clinical trials have suggested that raising HDL levels with niacin failed to demonstrate any improvement in cardiovascular outcomes. Furthermore, treatment with niacin was associated with an increased risk of stroke and increased diabetic complications. At this point, most doctors are very reluctant to prescribe niacin therapy for the purpose of raising HDL levels.
3. Beans. Beans are especially rich in soluble fiber. They also take awhile for the body to digest, meaning you feel full for longer after a meal. That's one reason beans are a useful food for folks trying to lose weight. With so many choices — from navy and kidney beans to lentils, garbanzos, black-eyed peas, and beyond — and so many ways to prepare them, beans are a very versatile food.
Who doesn't love avocados? They not only taste amazing but also can help lower your cholesterol. Avocados are high in healthy monounsaturated fat, which helps lower "bad" LDL cholesterol. They also contain fiber, antioxidants and phytosterols, such as beta-sitosterol, which have also been shown to lower cholesterol. Don't hog the entire bowl of guacamole, though! One serving is just a quarter of a Hass avocado, which delivers 57 calories. Spread a few slices of avocado on your sandwich instead of mayo, or dip some veggies into a bowl of fresh guacamole.
Many people don't like to hear it, but regular aerobic exercise (any exercise, such as walking, jogging or bike riding, that raises your heart rate for 20 to 30 minutes at a time) may be the most effective way to increase HDL levels. Recent evidence suggests that the duration of exercise, rather than the intensity, is the more important factor in raising HDL cholesterol. But any aerobic exercise helps.
Salmon is rich in omega-3 fatty acids, which are healthy fats that can help reduce blood pressure. Eating salmon can improve your "good" HDL cholesterol, but it won't lower your "bad" LDL cholesterol. HDL cholesterol helps sweep cholesterol off your artery walls, preventing dangerous plaque from forming. The American Heart Association recommends eating fatty fish like salmon at least twice per week for heart-healthy benefits. Other fish that contain omega-3s, such as mackerel, tuna and sardines, can also help.
Furthermore, in epidemiological studies involving over 100,000 individuals, people whose HDL cholesterol levels are below about 40 mg/dL had a substantially higher cardiac risk than those with higher HDL levels. This is the case even when LDL cholesterol ("bad" cholesterol) levels are low. Higher HDL levels have also been associated with a reduced risk of breast, colon and lung cancer.
If you smoke, it’s time to pack it in. According to the American Heart Association, smoking reduces your HDL cholesterol levels, while increasing your risk of heart disease, high blood pressure and diabetes. If you’re a smoker, you need to quit. Once you stop smoking, you can significantly improve your HDL cholesterol level very quickly and start protecting your heart. And if you’re a non-smoker, you need to avoid exposure to second-hand smoke to prevent your health from going up in smoke.
