First of all, develop good living habits.
1, have a good breakfast. There has always been a saying that "eat well at breakfast, eat well at lunch and eat less at dinner". If you don't eat breakfast, your blood sugar will be low and your brain's nutrition supply will be insufficient. When the homework is the most in the morning, the energy needed by the brain will not be supplied. In the long run, it will affect homework and brain development. Fresh milk is most suitable for breakfast, which not only contains high-quality protein, but also contains lecithin necessary for brain development. At the same time, it also needs the combination of grains, fruits and vegetables.
2. Ensure adequate sleep. Sleep is a period of rest and adjustment for the brain. Sleep can not only make the cells in the cerebral cortex not fail, but also replenish the consumed energy and achieve a new balance in the process of excitement and inhibition in the cerebral cortex. Good sleep can improve memory. Teenagers should ensure 8 hours of sleep every day. At the same time, you should be careful not to cover your head when you sleep, because when you sleep with your head covered, with the continuous increase of carbon dioxide concentration in the quilt, the oxygen concentration will continue to decrease, and the brain will not get sufficient oxygen supply, which will cause great harm to the brain for a long time.
3. Drink plenty of water. Water is the most important part of the human body. Studies have found that insufficient drinking water is an important reason for the accelerated aging of the brain. Teenagers should drink at least 8 glasses of water every day to ensure their physical needs.
4. Take part in physical exercise. Exercise can not only make bones and muscles strong, but also promote the development of brain and internal organs.
5, don't use your brain with illness. When you are in poor health or suffering from various acute diseases, you should rest. At this time, if you still insist on learning to use your brain, it is not only inefficient, but also easy to cause brain damage.
Second, a scientific and nutritious diet.
In order to meet the nutritional needs of the brain, nutritious foods with different functions should be matched into a balanced diet. Among nutrients and foods, the best brain-nourishing nutrients and foods that play an important role in the healthy development of the brain are:
1, fat is the primary substance for strengthening the brain. Fat plays an important role in the complex and subtle functions of the brain. Providing excellent and rich fat for the brain can promote the development of brain cells and the formation of nerve fiber myelin sheath, and ensure its good function. The best foods are sesame seeds, walnuts, animals raised in nature, other products and nuts.
2. protein is the material basis of intellectual activities. Protein is the main substance that controls the process of brain cell excitation and inhibition, and plays an important role in memory, language, thinking, exercise and nerve conduction. The best food is lean meat, eggs, bean products, fish and shellfish.
3. Carbohydrate is the energy source of brain activity. After carbohydrates are decomposed into glucose in the body, they become an important energy source for the brain. The content of main carbohydrates in food can basically meet the needs of the body. Too much sugar will make the brain into a state of excessive fatigue and induce neurasthenia or depression. The best food is miscellaneous grains, brown rice, brown sugar, cakes and so on.
4. Calcium is the substance to keep the brain working continuously. Calcium can keep the blood in a normal weak alkaline state and prevent people from falling into acidity and fatigue. Adequate calcium can promote the development of bones and teeth and inhibit the abnormal excitement of nerves. Severe calcium deficiency can lead to bad temper, hyperactivity, decreased disease resistance, inattention, mental retardation and even mental retardation. The best foods are milk, kelp, bone soup, small fish, seaweed, wild vegetables, bean products, shrimp skin, fruits and so on.
B vitamins are assistants of intellectual activities. B vitamins, including vitamin B 1, vitamin B2, vitamin B6, folic acid, etc. , is an assistant to brain activity. When it is seriously insufficient, it will cause mental disorders, irritability, inattention, difficulty in maintaining mental stability, and easily lead to heart, skin or mucosal diseases. The best foods are brown rice, wheat bran, mushrooms, wild vegetables, yellow-green vegetables, nuts and so on.
6. Vitamin C is the basic substance that makes you think quickly. Vitamin C can strengthen the structure of brain cells, play an important role in eliminating the relaxation and tension of brain cell structure, and make the body's metabolic function vigorous. Adequate vitamin C can make brain function flexible and sharp, and can improve IQ. The best foods are red dates, grapefruit, strawberries, watermelons, fresh fruits and yellow-green vegetables.
7. Vitamin A is a substance that promotes brain development. Vitamin A can promote the formation of skin and mucous membrane, make eyeball function vigorous, and promote the development of brain and bone. When it is seriously insufficient, it is prone to eye diseases such as night blindness, and it will also lead to mental retardation. The best food is eel, butter, milk, milk powder, carrots, leeks, oranges and so on.
8. Vitamin E is a substance that keeps the vitality of brain cells. Vitamin E has a strong antioxidant effect, which can prevent the production of lipid peroxide in the brain and prevent brain fatigue. When it is seriously insufficient, it will cause various types of mental retardation. The best food is sweet potato, lettuce, liver, butter and so on.
9. Carotene can prevent and treat mental retardation. Eating foods rich in carotene can prevent memory loss and other nerve damage. Carotene is an antioxidant and can also prevent mental retardation. Foods rich in carotene include rape, shepherd's purse, amaranth, carrot, cauliflower, sweet potato, pumpkin, yellow corn and so on.
