First, we should pay attention to rice, flour, corn and millet as the main food to ensure an important source of caloric energy for brain cells. Second, we should pay attention to the balance of amino acids in the brain, which helps brain nerve function and brain cell metabolism. Foods rich in high-quality protein include fish, eggs, dairy products, lean meat, etc. Third, we should pay attention to the intake of essential fatty acids. This fat in soybean oil, sesame oil, peanut oil, walnuts and other vegetable oils contain more unsaturated fatty acids. Can adhere to the daily consumption of a few walnuts, or melon seeds, pine nuts, etc., are good for the brain puzzle. Four to pay attention to the intake of fruits and vegetables. These foods are rich in vitamins, trace elements and dietary fiber, which have a protective effect on the brain. Vitamin C in the brain is like a lubricant; vitamin A can enhance the brain’s ability to discriminate; vitamin D is the brain tissue activities of the right “assistant”; B vitamins to ensure that the brain energy supply, help to overcome tiredness, fatigue, and can make people think clearly; vitamin E can effectively inhibit the decline of essential fatty acid cells in brain tissue Vitamin E can effectively inhibit the decline of essential fatty acid cells in brain tissue, necrosis, to extend the life span and maintain brain health. Five to pay attention to the brain supply of essential trace elements. For example, iodine is an important component of thyroxine, if the lack of iodine will lead to irritability and intellectual decline. Germanium is involved in the genetic process in the human body, can strengthen intelligence, so it is called “wisdom element”, and its content in ginseng and natural mineral water is more. Zinc is necessary for the synthesis of protein and nucleic acid in the brain, and a 48-hour lack of zinc in the human body will produce protein synthesis disorders, interfering with cell division, resulting in a decline in intelligence, and foods high in zinc include fish, meat, eggs and nuts. Iron is closely related to brain perception. Animal liver, bean foods, black beans, black fungus, black sesame, brown sugar and other foods are rich in iron. Calcium for the brain can inhibit abnormal excitation of brain nerves and bring the brain into a normal working and living state. Foods rich in calcium include milk, beans, black sesame, small fish, shrimp, shrimp, snails, etc.
