Stroke can be divided into hemorrhagic stroke and ischemic stroke, the former is mainly caused by hypertension, while the latter is mostly caused by diabetes, cerebral arteriosclerosis, hyperviscosity, etc. According to research findings, some of the people’s food has the effect of lowering blood pressure, softening blood vessels, etc., the usual intake of these foods can be very good to prevent the occurrence of stroke. 1, high potassium food. People who eat more fresh vegetables and fruits every day have a lower risk of stroke than those who eat only a small amount of vegetables and fruits, indicating that vegetables and fruits rich in potassium have an anti-stroke effect; this is because high potassium foods can adjust the ratio of sodium and potassium in the cells, reducing the retention of sodium and water in the body, reducing blood pressure and preventing the occurrence of hemorrhagic strokes. Foods rich in high potassium are spinach, tomatoes, green garlic, onions, potatoes and bananas, oranges, melons, grapefruit, etc. 2, rich in flavonoids and lycopene food. Atherosclerosis is mainly caused by “bad” cholesterol, reduce LDL and inhibit its oxidation to prevent atherosclerosis plays a very important role. The substance flavonoids and lycopene can capture oxygen free radicals, deterring the oxidation of LDL okapacillin, to prevent blood vessel narrowing and blood clots clogging cerebral vessels have a positive role in the daily diet rich in flavonoids and lycopene are onions, parsley, carrots, pumpkin, grass mold, apples, red grapes, tomatoes, watermelon, persimmons, sweet apricots, peppers and so on. 3, eat more high-quality protein food. Epidemiological survey data show that protein food intake is insufficient or poor quality, will increase the brittleness of blood vessels, easy to cause intracranial microaneurysm rupture bleeding. Studies have shown that eating foods rich in thionine, lysine, glucosine and taurine is not only beneficial for maintaining normal vascular elasticity and improving cerebral blood flow, but also promotes the excretion of sodium, which helps prevent the occurrence of stroke.
