Foods that are good for the heart include whole grains, oats, brown rice, beans, onions, garlic, eggplant, spinach, apples, bananas, almonds, peanuts, olive oil, and deep-sea fish. Among them, oats can effectively reduce the level of LDL cholesterol in the blood and help the body to keep the arterial blood vessels open, which has many benefits for the heart. Peanuts are rich in vitamin E, which can reduce platelet aggregation, soften blood vessels to make blood flow smoothly and reduce the occurrence of heart disease. Spinach contains folic acid, fiber, potassium and lutein, which help keep the heart healthy. One study found that eating spinach regularly can reduce the risk of heart disease by about 25%. Garlic lowers cholesterol and LDL, and also reduces platelet stickiness to prevent thrombosis. Eating a few cloves of garlic a day, preferably unprocessed or ungarlicized, can have a preventive effect on coronary heart disease. Onions have cholesterol-lowering effects. Whether raw, fried, stewed or boiled, onions are always a friend of the heart. Beans lower cholesterol and blood viscosity, and are a great source of heart protection as well as quality protein intake. Eating tofu and drinking soy milk are good choices. Olive oil is rich in unsaturated fatty acids, which can effectively lower cholesterol levels and reduce the risk of heart disease. Deep-sea fish are also heart-protective, such as salmon and sardines.
