Insufficient blood supply to the brain needs to eat a reasonable diet, especially eat breakfast, eat more food rich in vitamins and fiber and antioxidant. Every day, we should eat more fresh vegetables and fruits, such as: tomatoes, cucumbers, onions, broccoli, grapes, kiwi, etc. We can also eat fish, chicken and duck meat, black sesame and other foods to improve the brain metabolism, and we can drink some vinegar, dry red wine and other antioxidant foods in moderation. Patients with cerebral insufficiency of blood supply can also eat some walnuts, peanuts and other foods rich in unsaturated fatty acids. Although dietary therapy is very important, but after all, it is different from medication, and when suffering from cerebral insufficiency of blood supply, try to go to the hospital as early as possible to seek medical treatment, to clarify the causes of cerebral insufficiency of blood supply, to remove the risk factors, and to rationalize the use of medication.
