Under normal circumstances, the human body's blood is alkaline, and when the brain is used excessively or the physical exertion is too large, the blood is acidic. Therefore, if you prefer acidic food for a long time, it will make the blood acidic, and the brain and nerve functions will easily deteriorate, causing memory loss. Oranges contain a lot of vitamins A, B 1 and C, which are typical alkaline foods. 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.
2. Corn
Corn embryo is rich in linoleic acid and other unsaturated fatty acids, which can protect cerebral blood vessels and reduce blood fat. In particular, corn seeds have a high water content of glutamic acid, which has a brain-strengthening effect when eaten frequently.
3. Peanuts
Peanut is rich in lecithin and cephalin, which is an important substance needed by nervous system. It can delay the decline of brain function, inhibit platelet aggregation and prevent cerebral thrombosis. Lecithin is known as the "flower of wisdom" and has the function of rejuvenating the brain. Experiments show that eating peanuts regularly can improve cerebral blood circulation, enhance memory and delay aging, which is a veritable "longevity fruit".
4. Fish
It can provide high-quality protein and calcium to the brain, and the fatty acids contained in freshwater fish are mostly unsaturated acids, which can protect cerebral vessels and promote brain cell activities.
5. Pineapple
Pineapple contains a lot of vitamin C and trace element manganese, and it has less calories, so it often has the effect of refreshing the body fluid. Pineapple is often the favorite fruit of some musicians, singers and actors, because they have to recite a lot of music scores, lyrics and lines.
6. Eggs
Foods containing acetylcholine can affect people's mental state and memory. Eating 1 or 2 eggs a day can supply enough choline to the body, which is very helpful for protecting the brain and improving memory.
7, monosodium glutamate
The main component is sodium glutamate, which can be converted into glutamic acid under the action of gastric acid. Glutamate is the only amino acid that participates in human brain metabolism.
8. Kelp
Kelp is very alkaline, so people who often use their brains should eat more kelp.
9. Porphyra
Porphyra is rich in choline, and eating laver often can improve memory decline. Porphyra is also rich in vitamins and minerals, especially vitamins B 12, B 1, A, C, E and so on. It contains about the same protein as soybean, 6 times as much as rice, 67 times as much vitamin A as milk, and 8 times more riboflavin than mushrooms. It also has many functions such as tonifying kidney, nourishing heart, lowering blood pressure and promoting human metabolism. Porphyra can prevent human aging. It contains a lot of taurine, which can reduce harmful cholesterol and protect the liver. There are13 dietary fibers in laver, which can keep intestinal health and excrete carcinogens, especially for preventing colorectal cancer.
10, longan
Also known as longan. Contains protein, sugar, fat, minerals, tartaric acid, vitamin A, vitamin B 1, etc. Longan nucleus contains fat and tannin, which has auxiliary effects on neurasthenia, postpartum weakness, hypomnesis, insomnia, forgetfulness, palpitation and anemia.
1 1, honey
Contains acetylcholine, hormones and other ingredients, and has certain effects on neurasthenia, insomnia, neurosis and amnesia.
12, avocado
Avocado contains a lot of oleic acid, which is an energy source for short-term memory (remembering plans, timetables, shopping lists, etc.). Half an avocado a day is enough.
13, Apple
Eating an apple a day can make you quick-witted and have a good memory. Apple is not only rich in sugar, vitamins, minerals and other nutrients necessary for the brain, but more importantly, it is rich in zinc. Zinc is a component of many important enzymes in human body, and it is also an indispensable nucleic acid and an indispensable element for protein.
14, strawberry
Strawberry contains a sudden flavonoid called fisetin, which can stimulate signal pathway and improve memory.
15, blueberry
Wild blueberry fruit is rich in antioxidants, which can remove impurities from the body. Long-term intake can accelerate the growth and differentiation of neurons in the hippocampus of the brain and improve memory.
16, grapes
Grapes are rich in vitamin C, vitamin A and vitamin B, which is helpful for improving memory. Drinking grape juice often is beneficial to prolong life.
17, cabbage
Cabbage can help clean the unclean components in the blood, promote blood circulation in the brain, and is rich in B vitamins to prevent memory fatigue, thus enhancing memory.
18, soybean
Soybean contains egg yolk and rich protein. Eating proper amount of soybean or bean products every day can enhance memory.
19, apricot
Apricot is rich in vitamins A and C, which can effectively improve blood circulation, ensure adequate blood supply to the brain and help the brain to enhance memory.
other
In addition to the above foods, there are many foods that can strengthen the brain and improve intelligence, such as lean meat, fish, shellfish, animal offal, nuts (cashews and walnuts), cereals (millet and buckwheat), sprouts (alfalfa sprouts and bean sprouts), mushrooms, carrots, peppers, spinach, fungus and black sesame seeds.
