1. Milk. Milk is an almost perfect nutritional product. It is rich in protein, calcium, and amino acids essential for the brain. Calcium in milk is most easily absorbed by humans and is an indispensable and important substance for brain metabolism. In addition, it also contains vitamin B1 and other elements that are very beneficial to nerve cells. If you suffer from insomnia due to overuse of your brain, a cup of hot milk before going to bed can help you fall asleep.

2. Eggs. Brain activity function and memory strength are closely related to the acetylcholine content in the brain. Experiments have shown that the beauty of eating chicken is that when the lecithin contained in the egg yolk is decomposed by enzymes, rich acetylcholine is produced, which enters the blood and quickly reaches the brain tissue, 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.

3. Fish. They can provide high-quality protein and calcium to the brain. Most of the fatty acids contained in freshwater fish are unsaturated fatty acids, which will not cause vascular sclerosis and are not harmful to cerebral arteries. On the contrary, they can also protect cerebral blood vessels and promote brain cell activity. .

4. MSG. The main component of MSG is sodium glutamate, which can be converted into glutamic acid under the action of gastric acid. Glutamic acid is the only amino acid that participates in human brain metabolism. It can promote intellectual development, maintain and improve brain function. Regular intake of MSG can help improve mental retardation and memory impairment. Because MSG increases acetylcholine in the brain, it also has a certain effect on neurasthenia.

5. Peanuts. Peanuts are rich in lecithin and cephalin, which are important substances needed by the nervous system. They can delay the decline of brain function, inhibit platelet aggregation, and prevent cerebral thrombosis. Experiments have confirmed that regular consumption of peanuts can improve blood circulation, enhance memory, and delay aging. It is a veritable "immortality fruit."

6. Xiaomi. The vitamin B1 and B2 contained in millet are 1.5 times and 1 times higher than that of rice respectively, and its protein contains more tryptophan and methionine. Clinical observations have found that eating millet can prevent aging. If you often eat some millet porridge and millet rice, it will be beneficial to the health of the brain.

7. Corn. Corn embryos are rich in linoleic acid and other unsaturated fatty acids, which can protect cerebral blood vessels and lower blood lipids. In particular, corn contains high water content and glutamic acid, which can help promote brain cell metabolism. Eating corn, especially fresh corn, has a brain-building effect.

8. Daylily. People often say that daylily is the "forget-you grass" and can "calm the nerves and relieve depression". Note: Day lily should not be eaten raw or fried to avoid poisoning. It is better to eat it dry or cooked.

9. Chili. The vitamin C content of pepper ranks first among all vegetables, and it is also rich in carotene and vitamin content. The capsaicin contained in peppers can stimulate the sense of taste, increase appetite, and promote blood circulation in the brain. In recent years, some people have discovered that the "spicy" taste of chili peppers also stimulates the hormones in the human body that pursue career success, making people energetic and active in thinking. Chili peppers are better when eaten raw.

10. Spinach. Spinach may be cheap and inconspicuous, but it is a brain-boosting vegetable. Because spinach is rich in vitamins A, C, B1 and B2, it is one of the "best suppliers" of brain cell metabolism. In addition, it also contains a large amount of chlorophyll, which also has brain-building and intelligence-improving effects.

11. Orange. Oranges contain a lot of vitamins A, B1 and C, which are typical alkaline foods and can eliminate the harm caused by a large amount of acidic foods to the nervous system. During the exam period, eating some oranges regularly can make people energetic. In addition, lemon, mandarin orange, grapefruit, etc. also have similar effects and can replace oranges.

12. Pineapple. Pineapple contains a lot of vitamin C and trace element manganese, and has low calories. Regular consumption has the effect of promoting body fluids and refreshing people. Some people say it is a fruit that can improve people's memory. Pineapple is often the favorite fruit of some musicians, singers and actors because they have to memorize large amounts of music scores, lyrics and lines.
