People suffering from stroke should eat the following foods: 1) Foods rich in flavonoids and lycopene: Atherosclerosis is mainly caused by "bad" cholesterol, that is, low-density lipoprotein. Reducing low density lipoprotein and inhibiting its oxidation are very important for preventing atherosclerosis. Flavonoids and lycopene can capture oxygen free radicals, inhibit the oxidation of low density lipoprotein, and have a positive effect on preventing vascular stenosis and thrombosis from blocking cerebral vessels. There are onions, coriander, carrots, pumpkins, grasses, apples, red grapes, tomatoes, watermelons, persimmons, sweet apricots and peppers rich in flavonoids and lycopene in the daily diet. (2) Eat more high-quality protein food: insufficient intake or poor quality of protein will increase the fragility of blood vessels and easily lead to rupture and bleeding of intracranial microaneurysms. Studies have shown that eating more foods rich in methionine, lysine, glucuronic acid and taurine, such as fish, chicken and duck meat, rabbit meat and pigeon meat, is not only conducive to maintaining normal vascular elasticity, improving cerebral blood flow, but also promoting the excretion of sodium salt and preventing the occurrence of stroke. (3) High-potassium food: People who eat more fresh vegetables and fruits every day are less likely to suffer from stroke than those who eat only a small amount of vegetables and fruits, which shows that vegetables and fruits rich in potassium have the style of preventing stroke; Foods rich in potassium include spinach, tomatoes, green garlic, green onions, potatoes, bananas, oranges, melons and grapefruit.
