Oats:

Oats are a great source of soluble fiber, which can help reduce the absorption of cholesterol into your bloodstream.

Barley and other whole grains:

These can help lower the risk of heart disease, mainly via the soluble fiber they deliver.

Beans:

Beans are also high in soluble fiber, and they take a while for the body to digest, meaning you feel full for longer after a meal.

Nuts:

Studies have shown that eating almonds, walnuts, peanuts, and other nuts can be good for the heart.

Vegetable oils:

Using liquid vegetable oils such as canola, sunflower, safflower, and others in place of butter, lard, or shortening when cooking or at the table helps lower LDL (Low-Density Lipoprotein or "bad" cholesterol).

Fatty Fish:

Eating fish two or three times a week can lower LDL in two ways: by replacing meat, which has LDL-boosting saturated fats, and by delivering LDL-lowering omega-3 fats.

Fruits and vegetables:

These are high in fiber, including cholesterol-lowering soluble fiber, and they're low in saturated fat.

Fiber supplements:

Supplements like psyllium husk can provide you with extra fiber, which can help lower your LDL cholesterol.

Avocados:

These fruits are a rich source of monounsaturated fats and fiber — two nutrients that help lower "bad" LDL and raise "good" HDL cholesterol.

Soy:

Consuming soybeans and foods made from them, like tofu and soy milk, was once touted as a powerful way to lower cholesterol.

Garlic:

It’s believed that garlic can help lower blood pressure and cholesterol levels, although the effect is relatively small.

Dark Chocolate and Cocoa:

Some research suggests that dark chocolate and cocoa may reduce LDL cholesterol and increase HDL cholesterol.

Flaxseeds:

These seeds are a great dietary source of omega-3 fatty acids, fiber, and other nutrients. Flaxseed can reduce total cholesterol and LDL cholesterol levels.

Green Tea:

This beverage contains catechins and other antioxidant compounds that have been shown to lower cholesterol levels.

Extra Virgin Olive Oil:

This oil is high in monounsaturated fats and has been shown to reduce heart disease risk factors, including LDL cholesterol.

Remember to also maintain a balanced diet, exercise regularly, and consult with a healthcare professional before making major changes to your diet or taking supplements.
