While cholesterol is normally kept in balance, an unhealthy diet high in hydrogenated fats and refined carbohydrates can disrupt this delicate balance, leading to increased cholesterol levels. This imbalance is manifested in elevated LDL (bad cholesterol) and low HDL (good cholesterol), which increases the risk of heart attack or stroke. Other causes can include physical inactivity, diabetes, stress and hypothyroidism.
Resistance training is a form of physical activity that forces your muscles to contract, building up strength and endurance. Some research also shows that resistance training could have beneficial effects on heart health as well and may decrease total and LDL cholesterol. (31) Weight lifting and bodyweight exercises like squats or lunges are some examples of resistance training that you can add to your routine.
Trans fats are a byproduct of the chemical reaction that turns liquid vegetable oil into solid margarine or shortening and that prevents liquid vegetable oils from turning rancid. These fats have no nutritional value — and we know for certain they are bad for heart health. Trans fats increase LDL cholesterol and triglyceride levels while reducing levels of HDL cholesterol.
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
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.
Lentils are pulses, a.k.a. the dry edible seeds of certain crops (like beans, chickpeas, and peas). Pulses are just everywhere these days because they’re packed with plant-based protein and fiber, not to mention antioxidants, minerals, and B vitamins. All of those compounds help protect you from plaque buildup while optimizing blood flow and assisting your body in efficiently using the nutrients you consume.
"These fish are best for cholesterol, but any fish is better than red meat," says Pacold. “Every time you have fish as a protein source instead of red meat, you are doing your heart a favor.” If you don't eat fish, you can get your needed dose of omega-3s in the form of a diet supplement pill, he suggests. Flaxseeds, walnuts, and even mixed greens are plant-based options to get more omega-3s in your diet.
A largely vegetarian "dietary portfolio of cholesterol-lowering foods" substantially lowers LDL, triglycerides, and blood pressure. The key dietary components are plenty of fruits and vegetables, whole grains instead of highly refined ones, and protein mostly from plants. Add margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.

Heart-healthy eating. A heart-healthy eating plan limits the amount of saturated and trans fats that you eat. It recommends that you eat and drink only enough calories to stay at a healthy weight and avoid weight gain. It encourages you to choose a variety of nutritious foods, including fruits, vegetables, whole grains, and lean meats. Examples of eating plans that can lower your cholesterol include the Therapeutic Lifestyle Changes diet and the DASH eating plan.
HDL cholesterol carries excess cholesterol to your liver so it doesn’t build up in your bloodstream. But when LDL cholesterol moves cholesterol throughout your body, it can build up in the walls of the arteries, making them hard and narrow. If you have too little HDL cholesterol and too much LDL, you may be diagnosed with high cholesterol, a condition that can lead to atherosclerosis, angina (often experienced as chest pain), heart attack, and stroke.
Soy isoflavones significantly decreased serum total cholesterol by 0.10 mmol/L (3.9 mg/dL or 1.77%; P = 0.02) and LDL cholesterol by 0.13 mmol/L (5.0 mg/dL or 3.58%; P < 0.0001); no significant changes in HDL cholesterol and triacylglycerol were found. Isoflavone-depleted soy protein significantly decreased LDL cholesterol by 0.10 mmol/L (3.9 mg/dL or 2.77%; P = 0.03). Soy protein that contained enriched isoflavones significantly decreased LDL cholesterol by 0.18 mmol/L (7.0 mg/dL or 4.98%; P < 0.0001) and significantly increased HDL cholesterol by 0.04 mmol/L (1.6 mg/dL or 3.00%; P = 0.05). The reductions in LDL cholesterol were larger in the hypercholesterolemic subcategory than in the normocholesterolemic subcategory, but no significant linear correlations were observed between reductions and the starting values. No significant linear correlations were found between reductions in LDL cholesterol and soy protein ingestion or isoflavone intakes.
Chocolate fans rejoice! You might have heard that chocolate is good for you, and it's true. Dark chocolate and cocoa powder contain powerful antioxidant compounds called flavonoids, which help lower cholesterol. Milk chocolate has less cocoa solids, and thus lower flavonoid levels, and white chocolate is even lower in the good stuff. Reach for small portions of dark chocolate, preferably with a high cocoa content. Or try a sprinkle of cocoa powder in your smoothie or on yogurt to reap chocolate's cholesterol-lowering benefits.
Perhaps most disappointing of all, a new class of drugs (the so-called CETP-inhibitors), which several pharmaceutical companies have been enthusiastically developing for several years to raise HDL levels, has become a great disappointment. While these drugs do indeed increase HDL levels, they have not demonstrated an ability to improve cardiac risk — and on the contrary, studies appear to show a worsening in cardiac risk with some of these drugs. It is unclear today whether any CETP-inhibitors will ever reach the market.
Stick to a Low-Carb Diet – Also known as a ketogenic diet, a low-carb diet can lead to several health benefits, including weight loss, reduced blood sugar levels, and, of course, an increase in your HDL cholesterol. This is great for those who suffer from diabetes, metabolic syndrome, or obesity, but in truth, anyone can benefit from this type of diet!
Berberine – this is a plant-based natural supplement to raise HDL. It’s ideal for promoting healthy cholesterol and blood sugar levels. It may very well be the single most powerful supplement we carry. Due to soil depletion and modern farming practices, it’s nearly impossible to get the nutrition you need from food alone. Use Berberine as the supplement of choice to boost HDL.
Plasma HDL is a small, spherical, dense lipid-protein complex that is half lipid and half protein. The lipid component consists of phospholipids, free cholesterol, cholesteryl esters, and triglycerides. The protein component includes apo A-I (molecular weight, 28,000) and apo A-II (molecular weight, 17,000). Other minor, but important, proteins are apo E and apo C, including apo C-I, apo C-II, and apo C-III.
Nuts are high in polyunsaturated fatty acids, so almonds, walnuts, or pistachios can help reduce your LDL levels. Try sprinkling them on your salad, or eat them right out of hand as a snack. Just be sure to choose the low-salt option, and keep it to about 1.5 ounces a day -- nuts are also high in calories. For almonds, that’s about 30 almonds or 1/3 cup.
A meta-analysis looked at randomized controlled trials for artichoke extract for high cholesterol. They found three studies worth analyzing and two showed some effect in lowering total cholesterol. Adverse events were mild, transient, and infrequent. The study said that larger clinical trials over longer periods are needed. The conclusion was that the evidence was not convincing, and the Cochrane Review discontinued updating its analysis of this research as of 2016.
Flavor foods with herbs and spices whenever you can. It’ll help you cut back on condiments high in saturated fat while maximizing flavor. Spices and herbs also pack antioxidants, which can help improve cholesterol levels when combined with veggies. Ones we love: Basil, cilantro, rosemary, sage, ginger, garlic, tarragon, black and red chili pepper, mint, and oregano.
