The complexity and delicacy of the brain structure and the superb and complete function are unparalleled. All human activities, including language, emotion and behavior, are controlled and regulated by the brain. Although the weight of the brain only accounts for about 2% of human body weight, its blood flow requirement accounts for 15% ~ 20% of the whole body, and its oxygen demand accounts for 25% of the whole body, and it needs to consume 4 ~ 8 grams of glucose per hour. It can be seen that the brain is an organ that consumes a lot and needs to be supplemented with nutrition at any time.

Soybeans, fish, meat, eggs, milk, spinach, carrots, wheat, sesame, walnuts, seaweed and fruits are all ideal brain-nourishing foods, because these foods contain nutrients necessary for brain protection, such as unsaturated fatty acids, protein, vitamins and trace elements. The details are as follows:

(1) Eggs contain a lot of protein, fat, inorganic salts and vitamins, which are indispensable nutrients for brain metabolism. Acetylcholine contained in eggs is necessary for the brain to complete memory. Therefore, if teenagers can eat 1 egg for breakfast every day, it will not only improve the quality of breakfast and make the whole morning full of vitality, but also strengthen their bodies, strengthen their brains and improve their intelligence.

(2) Millet contains more nutrients such as protein, fat, calcium, iron, vitamin B, etc., and is a staple food for strengthening the brain. In addition, millet has the function of preventing and treating neurasthenia. Eating millet porridge at ordinary times is of great benefit to the health of the brain.

(3) Animal liver and kidney are rich in iron, which is an important component of red blood cells. Iron supply is sufficient, red blood cells have a strong function of transporting oxygen, and the brain can get enough oxygen, thus thinking quickly and remembering well.

(4) Walnuts and sunflower seeds contain more high-quality protein and fat. Unsaturated fatty acids contained in the fat are the main substances that constitute the human brain and are indispensable building materials for the brain.
