If the supply of various nutrients is needed to meet the normal needs of the brain, a reasonable dietary structure must be arranged according to the principle of nutritional balance. Prevent overeating, prevent excessive calories and prevent excessive intake of high-sugar and high-fat foods; It is necessary to adhere to the combination of thick and thin, the combination of meat and vegetables, the diversification of food varieties and comprehensive nutrition. Omnivorous food is good for IQ; Three meals a day should be arranged reasonably, and the intake of breakfast, lunch and dinner should be kept in an appropriate proportion to prevent overeating and hunger.

Maintain acid-base balance in diet

Under normal circumstances, the blood in human body is weakly alkaline, and its change is affected by the pH value of food. Be sure to mix acid and alkali in your diet. If you eat acidic food for a long time, it will affect the neurological function of the brain, cause memory decline, thinking decline, and even cause neurasthenia. Therefore, pay attention to eating alkaline foods in your daily diet. Foods that make blood weakly alkaline are tofu, peas, soybeans, mung beans, rape, celery, eggplant and cucumber, and foods that make blood weakly alkaline are spinach, cabbage, cabbage, lettuce and radish.

Appropriate supplementation of polyunsaturated fatty acids (DHA)

DHA is an essential substance for brain development and participates in the division and proliferation of brain cells. It can nourish brain cells, transmit information quickly, enhance memory, effectively prevent brain function decline, improve brain work efficiency, delay brain atrophy in the elderly and prevent the occurrence of Alzheimer's disease. Pay attention to eating more fish in the daily diet, especially the high DHA content of marine fish, which is conducive to strengthening the brain and increasing wisdom.

Appropriate supplementation of phospholipids

Phospholipids can provide the brain with the transmission material of activity information and activate brain cells, thus improving intelligence and memory. Besides egg yolk, food containing lecithin also includes animal liver, bean products, fish, meat and other foods. Therefore, eating 1 ~ 2 eggs a day can improve memory.

Replenish enough water

Lack of water in the brain will lead to premature aging, weight loss, memory loss and even aging due to lack of water, while blood is thick and slow, which is easy to form cerebral thrombosis. Therefore, to maintain the function of the brain, it is necessary to maintain adequate water. But don't drink too much water.
