The statement “the best food to prevent stroke” is not scientific. Foods have nutritional value, but they do not have the effect of preventing or treating diseases. People can eat more fresh fruits, such as bananas, etc.; protein-rich foods, such as milk, eggs, etc.; fresh vegetables, etc. to help the body supplement nutrients. 1. Fresh fruits, such as bananas, grapes, apples, etc., can replenish the micronutrients needed by the human body. 2. Protein-rich foods: such as milk and eggs are rich in protein, which can supplement the nutrients needed by the body. 3. Fresh vegetables: such as carrots, bok choy, cabbage, etc., can supplement the nutrients needed by the body. If you want to prevent stroke, you need to follow a diet low in salt, fat and sugar, and exercise appropriately to keep you in a good mood and under the guidance of your doctor.
