Modern nutrition research has found that after eating too much, the substance called "fibroblast growth factor" in the brain will increase significantly. Fibroblast growth factor can increase capillary endothelial cells and fat, and promote atherosclerosis. Long-term satiety will inevitably lead to cerebral arteriosclerosis, premature aging of the brain and mental retardation.
Alcohol weakens the inhibition of cerebral cortex, so people who drink alcohol feel top-heavy, unstable and slow. Alcoholism is particularly harmful to the brain. Sweet food will damage appetite, reduce appetite, reduce the intake of high protein and multivitamins, lead to malnutrition and affect brain development.
Thinking is the best way to exercise the brain. Only by thinking more and thinking more can people become smart. On the other hand, the less willing you are to use your brain, the faster it degenerates and the smarter you become.

With the increase of carbon dioxide concentration in the quilt, the oxygen concentration will continue to decrease. Inhaling humid air with high carbon dioxide concentration for a long time is very harmful to the brain.
The brain is the organ that consumes the most oxygen in the whole body. Only by ensuring sufficient oxygen supply can the working efficiency of the brain be improved. Therefore, when using the brain, we should pay special attention to the air hygiene in the working environment.
Skipping breakfast will deprive the body and brain of normal blood sugar supply. Insufficient nutrition supply to the brain is harmful to the brain over time. In addition, the quality of breakfast is also closely related to thinking ability. According to research, children who eat high-protein breakfast generally have longer optimal thinking in class, while vegetarian children's energy drops relatively quickly.
Sleep deprivation is the main way for the brain to eliminate fatigue. Long-term lack of sleep or poor sleep quality will accelerate the decline of brain cells, and smart people will become confused.
The10 people who are silent and unsmiling all day are just like "using them to get rid of them", and these functional areas will degenerate.
[Long-term smoking] German medical scientists' research shows that smoking all the year round will lead to different degrees of brain atrophy, and addicts are prone to Alzheimer's disease. This is because long-term smoking can cause cerebral arteriosclerosis, leading to insufficient blood supply to the brain, degeneration of nerve cells and brain atrophy.
Have a clever trick to strengthen the brain and improve intelligence
According to incomplete statistics, there are about1.40 ~1.500 million brain cells. After the age of 40, about 1 10,000 brain cells begin to die every day, and by the age of 60 or 70, it will be reduced by about one tenth. In order to prevent the decline of intelligence and delay the aging of brain function as soon as possible, people should learn to use and strengthen their brains scientifically.
Don't be afraid to use your brain. The more you use your brain, the more connections between various nerve cells in your brain, and the more conditioned reflex you form, the more flexible your brain will be. Scientists often test and find that people who often use their brains are not easy to get tired, and their brain cells are well maintained. Although they are getting older, they can avoid Alzheimer's disease. And people who have nothing to do and have no purpose all day long, not only have reduced intelligence, but also their brains are prone to atrophy and premature aging. The ancients advocated "erudition", which can enhance memory and promote erudition. The two complement each other. To achieve this goal, the key is to cultivate a strong interest in learning. Active and effective participation of the elderly in mental exercise can not only delay brain aging, but also prevent the occurrence of Alzheimer's disease.
Brain atrophy is a disease caused by the degeneration of the brain, mostly due to the lack of healthy qi in the process of aging, ignoring self-maintenance and self-prevention. Traditional Chinese medicine believes that "the kidney is the innate foundation, the main source of marrow, the brain, and the brain is the marrow sea." The brain is the mansion of Yuan God. If the brain marrow is insufficient, it will make you dizzy and tinnitus, and you will be blind. "The activity of the brain depends on the nourishment of kidney essence. People are old, qi and blood fail, kidney essence withers, complexion is yellow and white, and muscles and bones are weak. Temperance can nourish essence, which can replenish brain and delay brain aging. On the other hand, if you have excessive sexual life, you will be exhausted, premature aging, dizzy, mentally retarded, listless and sick.
Avoid excessive mental stress, arrange work, study and entertainment reasonably, make the excited parts of the cerebral cortex take turns to rest, and prevent excessive excitement from aggravating the burden on the nervous system. Whether nerve cells atrophy or not plays an important role in the process of human aging. Animal experiments have proved that excessive tension in the cerebral cortex is the only cause of premature aging in animals. When the normal function of human nervous system is destroyed and the internal and external environment is unbalanced, it will cause the low function of various organs and lead to premature aging. Therefore, maintaining the health of the nervous system is an important factor to prevent premature aging and brain dysfunction.
Ф ["brain-strengthening" exercise] After getting up every morning, go for a walk or do exercises outdoors; Play Tai Ji Chuan, or do Qigong or something. In the morning, the air is fresh, and the brain can get enough oxygen to awaken various neural mechanisms that are still in a state of inhibition. If you are tired of studying and working, you should adjust the environment, such as listening to good music, listening to beautiful birds, or looking at green grass like flowers. These activities can make people feel happy, cheer up and improve the activity function of the brain.
Sleep is an important way to rest the brain. When people sleep, the cerebral cortex is in a state of inhibition, and the energy substances consumed in the body are re-synthesized, so that the nerve center that becomes tired after excitement can regain its working ability. The quality of sleep is not all about the length of time, but more importantly, the depth of sleep, deep sleep, rapid elimination of fatigue, sleep time can be reduced.
Skill training of finger function can promote thinking, strengthen brain and improve intelligence, such as exercising with fitness balls. In other words, holding two iron balls or two walnuts in your hand and turning them constantly in your hand will have a good brain-strengthening effect for a long time. Regular finger skill activities can directly stimulate brain cells and enhance brain vitality. Make its function develop and keep the overall balance. As the saying goes, "ingenuity" is truth.

What brain-nourishing foods are there?
It is also beneficial to eat more digestible and nutritious foods, ensure enough protein, and eat foods rich in vitamin B and vitamin C, as well as foods rich in choline, such as apricots, bananas, grapes, oranges, fish and vegetables.
The metabolism of food in protein will produce a substance called cysteine, which is harmless to the body, but if the content is too high, it will cause cognitive impairment and heart disease. Moreover, once cysteine is oxidized, it will have toxic and side effects on the arterial wall. Vitamin B6 or B 12 can prevent cysteine-like oxidation, and the vitamin content in dark green leafy vegetables is the highest.
Fish fat contains omega-3 fatty acids, which can protect the nervous system and help to strengthen the brain. Studies show that people who eat fish at least once a week, especially salmon, sardines and herring, have a much lower incidence of Alzheimer's disease than those who seldom eat fish. Eating fish also helps to strengthen the activity of nerve cells, thus improving the ability of learning and memory.
Whole wheat products and brown rice are the best way to enhance the body's nutrient absorption ability. Brown rice contains a variety of vitamins, which is very important for maintaining cognitive ability. Among them, vitamin B6 is the most effective for reducing cysteine level.
The energy source of brain activity mainly depends on glucose. In order to make glucose play its due role, it is necessary to have enough vitamin B 1. Garlic itself does not contain a lot of vitamin B 1, but it can enhance the effect of vitamin B 1, because garlic can produce a substance called "alliin" with B 1, and the effect of alliin is much stronger than that of vitamin B 1. Therefore, proper consumption of garlic can promote the conversion of glucose into brain energy.
Protein contained in eggs is one of the best protein among natural foods, and it is rich in amino acids needed by human body. Egg yolk is rich in calcium, phosphorus, iron and vitamins A, D and B besides lecithin, which is suitable for mental workers.
The high-quality protein and 8 kinds of essential amino acids required by beans and their products are helpful to enhance the cerebrovascular function. In addition, it also contains lecithin, rich vitamins and other minerals, especially suitable for mental workers. Soybean fat contains 85.5% unsaturated fatty acids, among which linolenic acid and linoleic acid are more. They have the function of lowering human cholesterol, which is especially beneficial to the prevention and treatment of cardiovascular and cerebrovascular diseases for middle-aged and elderly mental workers.
Modern research has found that these two substances are very nutritious, especially unsaturated fatty acids. Therefore, regular consumption of them can provide enough unsaturated fatty acids with smaller molecules such as linoleic acid and linolenic acid for the brain to eliminate impurities in blood vessels and improve brain function. In addition, walnuts contain a lot of vitamins, which have a good effect on treating neurasthenia, insomnia, relaxing the mental state of the brain and eliminating brain fatigue.
Fruit pineapple is rich in vitamin C and important trace element manganese, which helps to improve people's memory. Lemon can improve people's acceptance; Bananas can provide tyrosine, an important substance in the brain, make people energetic, concentrate and improve their creativity.
