The main cause of myocardial ischemia is coronary atherosclerosis. Hypertension, high blood pressure and high blood sugar are the main risk factors of coronary atherosclerosis, so the diet of myocardial ischemia should be low salt, low fat and low sugar, and the intake of food rich in dietary fiber and vitamins should be increased. 1, staple foods: In addition to rice and noodles, staple foods should eat more various types of grains, grains are rich in nutrients and contain more dietary fiber.
