(1) starch-rich food brain activity is mainly supported by glucose oxidation in the brain after the release of energy, which relies mainly on the glucose in the brain to release energy, so to enhance memory, we need to have sufficient glucose and oxygen. The effect of improving memory is also supported by sufficient energy, which cannot be separated from the supply of glucose. Glucose is divided into single-molecule monosaccharides, multi-molecule polysaccharides and starch (a type of polysaccharide), which is made by the polymerization of glucose molecules. Biochemical proof, to the human body glucose monosaccharide, due to the immediate absorption without digestion, blood glucose concentration will rise abruptly, which in turn stimulates the pancreas to release large amounts of insulin, accelerate the glucose metabolism, so that the blood glucose concentration fell. This will affect the normal brain activity, unfavorable memory. And human starch from glucose into polysaccharides, need to be slowly digested, so that blood glucose does not rise suddenly, can constantly supply the brain oxidation energy. Therefore, sufficient starchy food is more favorable to brain activity. Starch-rich foods are mainly rice, noodles, corn, millet and groundnut, potatoes and so on.

(2)Foods containing lecithin and choline include soybeans, fava beans, mung beans, lentils, water chestnuts, eggplants, mushrooms, hawthorns, longan, peanuts, sesame seeds, eggs, liver, lean meat, milk and so on.

(3) eat food containing vitamin B1, vitamin C, vitamin B6, etc. and coarse grains vitamin Bl, vitamin B6 niacin. Folic acid and so on is acetylcholine, norepinephrine, dopamine, 5 ~ a hydroxytryptamine metabolism, as well as amino acid transformation in the indispensable coenzymes or raw materials constituting coenzymes, and directly affects the synthesis of neurotransmitters, impede the normal activity of the brain. Therefore, to improve memory, we must eat appropriate coarse grains to obtain enough vitamin B1, vitamin B6, vitamin C, etc..

(4) fatty acid-containing foods essential fatty acids are also important substances to improve brain activity, you can always eat some peanuts, walnuts, sesame seeds and so on. Stir fry with soybean oil, peanut oil, corn oil, lotus seed oil, etc., vegetable oil is good.

(5) caffeine foreign scholars on caffeine on various parts of the brain as a piece of the whole process of research. They found that caffeine can improve people's short-term memory. But this memory is short-term.
