Fish can be fatty or lean, but it’s still low in saturated fat. Eat at least 8 ounces of non-fried fish each week, which may be divided over two 3.5- to 4-ounce servings. Choose oily fish such as salmon, trout and herring, which are high in omega-3 fatty acids. Prepare fish baked, broiled, grilled or boiled rather than breaded and fried, and without added salt, saturated fat or trans fat. Non-fried fish and shellfish, such as shrimp, crab and lobster, are low in saturated fat and are a healthy alternative to many cuts of meat and poultry.
Kimchi, a Korean fermented side dish commonly made from cabbage, radish or cucumber, is quickly gaining a following for its many health benefits. Kimchi is high in fiber and—because it's fermented—is loaded with good bacteria that help keep your gut healthy. Kimchi contains bioactive compounds that lower cholesterol by blocking cholesterol from being absorbed into the bloodstream. The good bacteria produced during fermentation also help lower cholesterol. Kimchi and sauerkraut are usually pretty high in sodium, so watch your portions if you're watching your salt intake.
In both studies, mega-doses of statins (a doubling and tripling of regular doses) drove LDL levels way down. But in both studies, mega-doses also caused problems. Suffering from adverse side effects like muscle pain, memory loss, and elevated liver enzymes, patients on the high doses stopped taking their medications at twice the rate of patients on regular doses.
A 2014 study published in the journal PLoS One found that a diet rich in foods including fish, especially fatty fish, increased the size of HDL particles, which may help improve cholesterol transport throughout the body. The American Heart Association recommends eating fish at least twice a week, especially varieties that contain omega-3 fats, such as salmon, trout, and herring. A serving is considered 3.5 ounces cooked.
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.
Including fish in your diet can increase HDL cholesterol in a short period of time. In a study published in February 2014 in the journal PLoS One, researchers concluded that a diet rich in foods including fish showed an increase in the size of HDL particles in the body, which could help improve cholesterol transport through the body. The researchers saw the positive effects of a diet that included fish in as little as 12 weeks.
Foods high in monounsaturated fats (such as olive oil, nuts, and the oils in many salad dressings) seem to boost HDL best; it’s likely that foods high in omega-3 fatty acids (such as cold-water fish) do so as well. Saturated fats, the kind in meat and dairy foods, are likely to drive up harmful LDL, so take this opportunity to cut way back. Worst of all are trans-fatty acids, the hardened oils often found in margarine, crackers and other snack foods-a substance Harvard Medical School nutrition expert Walter C. Willett, M.D., author of Eat, Drink, and Be Healthy, calls “uniquely bad.” These foods can do exactly the opposite of what you want, lowering HDL while raising LDL.
There's no magical food to keep your heart healthy, but there are a lot of foods that can help—including these foods that help lower your cholesterol. In addition to cutting back on foods that can raise total cholesterol and getting enough exercise, make sure to eat more of these foods that improve your cholesterol profile by raising "good" HDL and/or lowering "bad" LDL cholesterol. These foods include some old standbys, such as oatmeal and fruit, plus a few surprising foods that can help lower cholesterol to reduce your risk of heart attack and stroke.
