Fiber is your friend when cholesterol is the enemy, so reach for foods that are full of soluble fiber. Just be aware that fiber comes in different forms, with one called soluble fiber and the other known as insoluble fiber. While both are good for your heart, it’s soluble fiber that’s great for your cholesterol. In addition to making you feel full, soluble fiber can actually reduce the amount of cholesterol your body absorbs. According to the Mayo Clinic, eating at least five to 10 grams of soluble fiber each day can lower both your LDL and total cholesterol levels. So better fill up your kitchen, along your body, with fiber-filled foods.
The good news is that changing your cholesterol levels is well within your control as some of the smallest lifestyle tweaks can yield a profound impact. A fast track to boosting HDL includes quitting smoking and increasing physical activity. The American Heart Association recommends 30 minutes of moderate physical activity at least 5 times per week with two sessions of resistance training. Your choices at mealtimes, however, may prove to be an easier more attainable way to make lasting change. Here are the foods that raise HDL cholesterol.
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.

Black beans, kidney beans, lentils, oh my! All are rich in soluble fiber, which binds to cholesterol in the blood and moves it out of the body. Recent studies show eating 4.5 ounces of beans a day can reduce LDL levels by 5 percent. Try black bean burritos, or dip some veggies in hummus, which is made with chickpeas, for an afternoon snack. Or try this Caramelized Onion and White Bean Flatbread -- beans are so versatile, the possibilities are endless.
Swap extra-virgin olive oil for all your other oils and fats when cooking at low temperatures, since extra-virgin olive oil breaks down at high temperatures. Use the oil in salad dressings, sauces, and to flavor foods once they’re cooked. Sprinkle chopped olives on salads or add them to soups, like in this Sicilian fish soup. Just be sure to use extra-virgin olive oil in moderation, since it’s high in calories.
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.
Cholesterol is then returned to the liver by multiple routes. In the first route, cholesterol esters may be transferred from HDL to the apo B–containing lipoproteins, such as very–low-density lipoprotein (VLDL) or intermediate-density lipoprotein (IDL), by CETP. These lipoproteins undergo metabolism and subsequent uptake by the liver, primarily by a process mediated by the B,E receptor. In the second route, HDL particles may be taken up directly by the liver. In the third, free cholesterol may be taken up directly by the liver. Finally, HDL cholesterol esters may be selectively taken up via the scavenger receptor SR-B1.
HDL levels below 40 mg/dL are associated with an increased risk of CAD, even in people whose total cholesterol and LDL cholesterol levels are normal. HDL levels between 40 and 60 mg/dL are considered "normal," and do not very much affect the risk of CAD one way or the other. However, HDL levels greater than 60 mg/dL are actually associated with a reduced risk of heart disease.
Saturated fats. Typical sources of saturated fat include animal products, such as red meat, whole-fat dairy products, and eggs, and also a few vegetable oils, such as palm oil, coconut oil, and cocoa butter. Saturated fat can increase your levels of "bad" LDL cholesterol. But it has some benefits, too — it lowers triglycerides and nudges up levels of "good" HDL cholesterol.
In a Canadian study, drinking a few glasses of orange juice every day for four weeks increased participants’ HDL by 21 percent, possibly due to a flavonoid called hesperidin that appears extremely HDL-friendly. Subsequent research found that tangerine juice may be even more effective. Unfortunately, that much juice will add hundreds of excess sugar calories to your diet. So stick to a glass a day and be satisfied with lesser results. Or you can buy hesperidin as a supplement, though it won’t replace the many beneficial nutrients of orange juice (and certainly won’t taste as good).
As you already know, HDL is considered the good guy in the cholesterol game, and it can help your liver to get rid of the unhelpful cholesterol in your body. This is a very important task that HDL is able to accomplish since cholesterol can’t simply dissolve into the blood. The liver has the job of processing cholesterol among its other important jobs. HDL is the liver’s helper and a very good one at that. Having high levels of HDL reduces your risk for both heart disease and stroke, which is why you want to get your cholesterol under control. (10)
A cup of tea does more than soothe on a stressful day. Both green and black tea can help lower cholesterol levels. Green tea is prepared from unfermented leaves and black tea from fully fermented leaves of the same plant. Researchers believe that catechins, a type of antioxidant found in tea, are responsible for its cholesterol-lowering effect. The more fermented the tea leaves, the lower the catechin content and the higher the caffeine content.
Why is one form of cholesterol considered good and another bad? There are actually as many as 18 kinds of cholesterol, but to save confusion, doctors divide them into two categories: LDL (bad) and HDL (good). Your liver manufactures most of your cholesterol, and small amounts of it go toward a variety of healthy purposes, including creating hormones that help turn food and exercise into muscle. Serving as cholesterol chauffeurs are fat/protein bunches called lipoproteins, and that’s where the fun begins: Low-density lipoproteins tend to deposit cholesterol on artery walls, where it builds up and eventually interferes with blood flow. But the high-density variety seems to take cholesterol back to the liver, where it can be eliminated from the body.
There are two types of dietary fiber: soluble (viscous) and insoluble. To receive the greatest health benefit, eat a wide variety of all high-fiber foods. Refined foods, like white bread, white pasta and enriched cereals are low in fiber. The refining process strips the outer coat (bran) from the grain, which reduces the amount of fiber that's left.
