1, pineapple: improve memory pineapple contains a lot of vitamin C and trace element manganese, and it has less calories. It is often eaten with the effects of promoting body fluid and refreshing. Some people call it a fruit that can improve people's memory. Pineapple 2, oranges: make people energetic oranges contain a lot of vitamins A, B 1 and C, which are typical alkaline foods and can eliminate the harm caused by a large number of acidic foods to the nervous system. Eating some oranges in moderation during the exam can make people energetic. In addition, lemon, mandarin orange, grapefruit, etc. have similar effects and can replace oranges. 3, peanuts: delay the decline of brain function peanuts are rich in lecithin and cephalin, which are important substances needed by the nervous system, can delay the decline of brain function, inhibit platelet aggregation, and prevent cerebral thrombosis. Experiments have proved that eating peanuts regularly can improve blood circulation, enhance memory and delay aging, which is a veritable "longevity fruit". 4. Corn: Protecting Cerebrovascular Corn embryo is rich in linoleic acid and other unsaturated fatty acids, which can protect cerebrovascular and reduce blood fat. In particular, the water content of glutamic acid in corn is high, which can help promote the metabolism of brain cells. Eating some corn, especially fresh corn, often has a brain-strengthening effect. 5, eggs: enhance memory brain activity function, memory strength is closely related to the content of acetylcholine in the brain. Experiments have proved that the beauty of eating chicken lies in that when the rich lecithin in egg yolk is decomposed by enzymes, it can produce rich acetylcholine, which will soon reach the brain tissue after entering the blood, which can enhance memory. Foreign studies have confirmed that eating 1 or 2 eggs a day can supply enough choline to the body, which is of great benefit to protecting the brain and improving memory. 6, milk: relieve insomnia caused by excessive brain use. Milk is a nearly perfect nutrient. It is rich in protein, calcium and essential amino acids for the brain. Calcium in milk is most easily absorbed by people and is an indispensable and important substance for brain metabolism.

If you use your brain too much to lose sleep, a cup of hot milk before going to bed will help you fall asleep. 7. Fish: Prevention of Dementia

They can provide high-quality protein and calcium to the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which will not cause arteriosclerosis and have no harm to cerebral arteries and vessels. On the contrary, they can also protect cerebral vessels and promote brain cell activities.
