Breast milk: Breast milk contains a variety of active substances that promote children's intellectual development, especially taurine, which has an important influence on intellectual development, is 10 times higher than milk. According to the survey, the IQ of children who grow up with breast milk is about 3 ~10 higher than that of children who grow up with milk substitutes.
Diet: Children who eat too much meat or gluttony will have reduced intelligence. The intelligence of children who skip breakfast will be affected, because protein, sugar, vitamins and trace elements in breakfast are all important ingredients for brain health.
Obesity: Children who weigh more than 20% of normal children will have a low level of vision, hearing and ability to accept knowledge. This is because too much fat in obese children enters the brain, which will hinder the development of nerve cells and the proliferation of nerve fibers.
Environment: Children who live in boring environment, such as abandoned babies, can't get maternal love and good education, and their IQ will be lower. According to the survey, the average IQ of such children is only 60.5 at the age of 3, whereas the average IQ of 3-year-old children in good environment is 9 1.8.
Drugs: Some drugs will affect children's intelligence. For example, taking antiepileptic drugs for a long time can make their IQ low, and after stopping taking drugs for several years, their IQ will be improved.
Improve IQ and find a way together
Prenatal education stimulates development
The fetus will feel it in about 3 months. When the mother touches the abdominal wall, the fetus will respond with a kick. By 4 months, the fetus is aware of the external sound, and can feel any sound that can pass through the mother. This is because the ability of human blood to transmit sound waves is much greater than that of air. This kind of sound constantly stimulates the fetal sensory organs and promotes their development, which plays an important role in the development of human intelligence. By 5 ~ 6 months, the fetal cerebral cortex structure has basically formed, and its touch, sight, hearing and taste have developed to a considerable extent, and it can feel some activities outside. At this time, playing some music and giving prenatal education such as abdominal massage to pregnant women can promote the intellectual development of the fetus.
Alkaline food is good for baby.
Human body fluids are slightly alkaline, which is beneficial to the body's absorption and utilization of substances. If children lack alkaline substances, it will affect hormone secretion and nerve activity, and this kind of children's IQ is low. It can improve children's diet structure, and eating more alkaline foods can improve their academic performance.
Generally speaking, green vegetables, nuts, fruits, low-fat milk, various mushrooms, beans and bean products, kelp, etc. are all alkaline foods. Meat, fish, flour, rice and peanuts, such as pigs, cattle, sheep, chickens and ducks, are acidic substances after being metabolized by the human body, so they belong to acidic substances.
Some foods, such as walnuts, frogs, pearls, animal brains and red dates, can enhance intellectual development. Foods high in vitamin C are also beneficial to improve IQ. When orange juice with high vitamin C was given to the children for 18 months, their IQ increased by 3.6 on average compared with those who did not use it.
Caress and cultivation promote growth.
Gently stroking the baby can promote the baby's growth and development. Massage the baby's head, neck, chest and limbs three times a day and touch the baby's whole body for 15 minutes every day for more than 10 days.
Enhancing children's memory depends on their usual efforts. Parents should often chat with their children, sometimes say a short sentence, and then ask them to tell it backwards. When walking, let the children remember the names of shops and roads they pass by, and then recite them to see how many they can remember.
Books are an excellent means to improve children's intelligence, and color pictures, such as a dog, an apple, a pen, etc., should be selected for babies under 1 year old. Use pictures to let them know what they can't see or connect with what they can see. For1~ 2-year-old children, books with large pictures and characters should be chosen, which can reflect things they are familiar with, such as flowers, animals, houses, etc., and be related to words. Children aged 2 ~ 3 should choose picture books with story content, and cooperate with children's songs that can be read along. Children aged 3-4 should choose books with new things and more details, such as animal stories, short fairy tales, and short Tang poems. Although they are not well understood, they are also conducive to enhancing their memory. When telling stories to children, children should be encouraged to ask questions and interrupt, so as to improve their interest in learning and thinking ability.
Richard M. Restak suggested in "The Brain: The Last New Field" that brain function depends largely on what you eat for breakfast.
There are trillions of nerve cells in the brain constantly engaged in heavy activities, and diet plays a very important role in the normal operation of the brain.
The adult brain only accounts for 2% of the total weight, but it uses 20% of the total energy. If you supply the brain with low-energy food, it will not work well; With high-energy food, it can work smoothly and efficiently.
Therefore, knowing the right "brain food" for the brain is one of the initial steps to improve learning ability.
First, brain nutrition
Some foods not only help to develop intelligence, make thinking more agile, concentrate more, enhance memory, improve learning ability in an all-round way, and stimulate people's creativity and imagination, but also help people cope with stress, overcome depression caused by slow thinking and eliminate pain.
1? Acetylcholine and lecithin
Recent studies in the United States, Britain, Canada and other countries point out that brain function and memory strength are closely related to the content of acetylcholine in the brain besides active exercise and mastering the laws of memory. Eating food rich in lecithin about one and a half hours before the exam can increase people's chances of winning. Experiments show that lecithin can improve people's intelligence by 25%.
Choline-rich foods include: barley malt, peanuts, eggs, veal liver, whole wheat flour, rice, trout, pecans with thin shells and so on.
2? protein
Adequate protein is a necessity for brain function. Many chess champions eat mainly protein before the exhausting game. Protein, especially fish, is an important brain food. But at dinner, should we eat fish or carbohydrates first? Two competing amino acids in protein-alanine and tryptophan-compete to enter the brain first. The first cells to enter the gray matter of the brain play an overall role.
If you want to stay alert after a meal, you should eat protein food first, then carbohydrate, that is, eat fish first, then potatoes and staple food; If you want to relax or take a nap after a meal, eat the staple food first. What to eat first is the key to the immediate impact of diet on brain power. If brainworkers need to keep their heads sharp all day, they should start with a high-protein breakfast, and lunch should be high in protein and low in carbohydrate, and carbohydrate food should be eaten later.
In seafood, beans, poultry and meat, there are a lot of anthranilic acid, which is the main brain stimulating substance; In cereals, bread, dairy products, potatoes, noodles, bananas, sunflower seeds and other foods, tryptophan is rich. Although it is also a food needed by the human brain, it often has a direct inhibitory effect on brain power for a certain period of time, and it is easy to cause drowsiness after eating.
3? glucose
The brain needs100 ~150 grams of sugar every day. However, the sugar content in the nervous system is very small, and glucose must be supplied by blood at any time. When blood sugar drops, the oxygen consumption of the brain drops, and people who are light will feel tired and unable to concentrate on their studies, and those who are heavy will be in a coma.
It is especially easy to happen to people who don't eat breakfast. Fresh fruits and vegetables, cereals and beans are rich in glucose.
4? vitamin
Vitamins A, B and C are very helpful for abstract thinking and good memory.
Vitamin C, known as the brain pump, is a necessary substance for the highest level of mental activity, which can improve about 5 IQ indexes.
Lack of vitamin B 1 will lead to depression, and lack of vitamin B2 will lead to depression, irritability and fear even for people with stable psychology. Lack of vitamin B6 will reduce serotonin, and less serotonin will lead to depression; Lack of vitamin B 12, manifested as emotional out of control or long-term fatigue, is easily mistaken for premature aging.
Vitamin E is the guardian of brain function, protecting nerve cell membrane and brain tissue from free radicals that destroy brain power, prolonging life and slowing down aging. Rich foods include nut oil, seed oil, soybean oil, barley malt, grain, nuts, eggs and dark leafy vegetables.
Vitamin A also protects brain nerve cells from free radicals. Rich foods include animal liver, fish oil, carrots, spinach, loose-leaf cabbage, sweet potatoes, pumpkins, apricots, papaya and all yellow or orange vegetables.
People with severe vitamin deficiency can take medicine to supplement, but they should follow the doctor's advice and not overdo it.
5? mineral
Certain minerals are also essential elements to activate the brain. Sodium, zinc, magnesium, potassium, iron, calcium, selenium and copper can prevent memory degradation and aging of nervous system, and enhance the system's resistance to free radicals. Many fruits and vegetables are rich in minerals.
Iron deficiency will reduce attention, delay the development of understanding and reasoning ability, damage learning and memory, and make academic performance decline; Lack of sodium will reduce the amount of information received by the brain; Zinc can enhance memory and intelligence and prevent Alzheimer's disease. Zinc deficiency can make people sleepy, depressed and children's development stagnate. Lack of potassium can lead to anorexia, nausea, vomiting and drowsiness; Calcium can activate nerve media and improve memory efficiency. Calcium deficiency can cause insanity, insomnia and spasm. Without magnesium, the synthesis of human lecithin will be inhibited, causing fatigue and memory loss.
Second, food to enhance memory
Some brain-nourishing foods are actually common and inexpensive things. Such as egg yolk, soybean, lean meat, milk, fish, animal viscera (heart, brain, liver, kidney), carrots, cereals, etc. These foods are not only rich in lecithin, but also easy to digest and have a positive effect on the development of children's brain marrow.
1? Milk It is rich in protein, calcium, vitamin B 1 and amino acids necessary for the brain. Calcium in milk is the most easily absorbed. A cup of hot milk helps you fall asleep when you are overworked or insomnia.
2? Eggs. Known by nutritionists as the complete protein model, the absorption rate of human body is 99.7%. An egg a day is enough for normal people. People with poor memory can effectively improve their memory by eating 5 ~ 6 pills a day (not suitable for people with high cholesterol). Children eat eggs properly from an early age, which is good for developing memory.
3? Fish. Can provide high-quality protein and calcium to the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which can protect cerebral vessels and promote brain cell activities.
4? Shellfish. The content of carbohydrate and fat is very low, almost pure protein, which can quickly supply the brain with a large amount of methionine. Therefore, it can greatly stimulate brain energy, improve mood and improve brain function. Taking shellfish as an appetizer can improve brain power the fastest. But shellfish are more likely to accumulate toxins and pollutants in the ocean than fish.
5? Monosodium glutamate. The main component is sodium glutamate, which is the only amino acid participating in brain metabolism. It can increase acetylcholine in the brain, promote intellectual development, maintain and improve brain function and improve memory.
6? Peanuts. Nuts such as peanuts are rich in lecithin, which can improve blood circulation, inhibit platelet aggregation, prevent cerebral thrombosis, delay brain function decline, enhance memory and delay aging. It is a veritable "longevity fruit".
7? Xiaomi. B 1 and B2 are higher than rice1~1? Five times. Clinical observation shows that eating millet is beneficial to brain health care and can prevent aging.
8? Corn. Corn embryo is rich in a variety of unsaturated fatty acids, which can protect cerebrovascular and reduce blood fat. Glutamate content is high, which can promote the metabolism of brain cells and has the function of strengthening the brain.
9? Day lily Day lily can soothe the nerves and relieve depression, but it should not be eaten raw or fried alone to avoid poisoning. It is better to eat it dry and cooked.
10? Pepper. Vitamin C ranks first among vegetables, and it is also rich in carotene and vitamins. Capsaicin contained in pepper can stimulate taste, increase appetite and promote blood circulation in the brain. The "spicy" flavor is also a hormone that stimulates the pursuit of career success in the human body, making people energetic and active in thinking. Raw food is better.
1 1? Spinach. Rich in vitamins A, C, B 1 and B2, it is one of the best suppliers of brain cell metabolism. It also contains a lot of chlorophyll, and it also has the function of strengthening the brain and improving intelligence.
12? Oranges Oranges, lemons, tangerines, grapefruit, etc. contain a lot of vitamins A, B 1 and C, which are typical alkaline foods and can eliminate the harm caused by a lot of acidic foods to the nervous system. Eating some oranges in moderation during the exam can make people energetic.
13? pineapple Rich in vitamin C and trace element manganese, and low in calories, it is often used to refresh the body fluid and improve memory.
14? Carrot. It can stimulate brain material exchange and relieve the pressure of back pain.
15? Avocado It contains a lot of oleic acid, which is the energy source of short-term memory. Normal people can have half an avocado every day.
16? Algae. Rich in chlorophyll, vitamins, minerals and protein, it can improve memory and attention.
Third, brain-strengthening herbs:
Recently, British research found that Ginkgo biloba and ginseng have the effects of accelerating people's reaction ability, improving memory and concentrating. The researchers gave the subjects these two herbs, and the results showed that taking 360 grams of ginkgo biloba or 400 milligrams of ginseng could enhance their memory.
Ginkgo biloba The oldest tree species on the earth has a history of 300 million years. Ginkgo biloba leaves have always been used as brain tonic by Chinese medicine. It can promote cerebral capillary circulation, increase the oxygen supply to the brain, quickly enhance the alertness of the brain, improve short-term memory, treat memory loss, depression, dizziness and tinnitus, and prevent dementia. At present, European countries prescribe Ginkgo biloba extract worth 500 million dollars every year.
Ginseng. In China, it has always been the king of health and longevity supplements, and its effect on the brain is similar to that of ginkgo biloba. It can regulate all physiological systems of human body, balance blood sugar, promote metabolism, regulate heart rate and balance blood pressure. Because ginseng can improve the level of a neurotransmitter that is very important for mood and memory, it can make people concentrate, alert their minds, think quickly and efficiently, enhance short-term memory and long-term memory, and improve their learning ability. Especially in the case of tension, fatigue and overwork, ginseng can play a role in calming, eliminating fatigue, regulating emotions, enhancing the ability to resist tension and stress, and improving brain function.
Mint. It can prevent brain blood circulation from being blocked, strengthen and stabilize nerves, improve attention, concentrate and finish work efficiently. Students can get better results by taking it before the exam.
Scutellaria baicalensis Georgi A highly effective nerve tranquilizer can prevent and treat insomnia and nervous tension.
Fourth, bad eating habits and environmental pollution damage memory.
Dr. Dannheim Haarman suggested that there is a substance called free radical in human body, which may be the main factor leading to the decline of human organs. It can dissimilate deoxyribonucleic acid (DNA), damage the brain through deoxygenation, suffocate nerve cells, and lead to many signs of aging, such as memory loss, Alzheimer's disease, dry skin, increased wrinkles, senile plaque, arthritis, cataract, arteriosclerosis, cancer and stroke.
1? Environmental pollution makes free radicals everywhere. Such as X-ray, microwave, nuclear radiation, toxic heavy metals (such as aluminum and cadmium found in domestic water), smoke, food chemical additives, smoke produced by cigarettes, automobile exhaust gas, hydrogenated vegetable oil and artificial unsaturated fat substitutes, such as margarine, catalytic oxygenated vegetable oil, cream without dairy products, most bottled salad dressings, and low-quality edible oil.
As soon as you eat such products (processed food, food in restaurants and fast food restaurants), they form free radicals in the human body. Processing food (such as French fries) with this oil at high temperature will accelerate its oxidation and release more free radicals. Most of the free radicals will enter the brain, which is the most vulnerable part of the human body.
Therefore, we need to pay special attention to getting rid of bad eating habits and resisting the damage to the brain caused by pollution.
2? High-fat food: A study by Canadian scientists found that a high-fat diet may impair memory and concentration. Experiments have proved that the ability of memory, learning and concentration of mice eating high-fat food is obviously weakened. After three months, there will be various serious dysfunction in learning and memory.
3? Alcohol and tobacco: Excessive drinking and smoking will destroy the synthesis of protein by brain cells, resulting in memory loss. Every time a smoker smokes a cigarette, it will reduce 25 mg of vitamin C in his body.
4? Avoid water and food contaminated by heavy metals. Once lead, aluminum and other heavy metals enter the human body, it is difficult to excrete them. Long-term intake will cause Alzheimer's disease. Therefore, long-term use of aluminum tableware, cooking utensils, or favorite foods with alum, such as fried dough sticks and vermicelli, will increase the aluminum content in the body. Excessive consumption of lead-containing preserved eggs can cause lead poisoning. Similarly, drinking water should also avoid pollution, and it is best to drink relatively pure water.
5? Pay attention to electromagnetic pollution:
Electromagnetic pollution in our daily environment can cause confusion, fuzzy memory, depression and brain function damage. Such as air conditioners, televisions and computers. American scientists found that when a weak electromagnetic field, which is very common in household appliances, was released to the subjects, their short-term memory decreased. Tests in the former Soviet Union show that low-frequency electromagnetic fields can cause ADHD, interfere with sleep habits, and damage memory and logical thinking.
Radiation from TV broadcast towers, high-voltage power lines, airports, radars and household appliances will produce electronic smoke, which can affect memory, lead to loss of learning ability, confusion of brain and behavior, and cause depression.
At present, people are only concerned about tangible pollution such as waste, waste water, waste gas and pesticides. In 2 1 century, people will pay more attention to the harm caused by electromagnetic pollution. Eliminating electromagnetic pollution will also become the same subject of the whole society and even the whole world.
6? Overeating: Overeating makes the body and brain tired, so it will be "full", which will affect intellectual development for a long time.
7? Long-term consumption of fast food and convenience food is insufficient or monotonous, which affects physical and mental health.
8? Taking sleeping pills and sedatives for a long time will cause damage to the brain.
9? Wolf down and never get tired of eating: once the food is refined, it becomes delicate, soft and tastes good, which is easy to chew and swallow. However, eating soft food exclusively is not good for the brain. A nutritionist pulled out all the left teeth of a little monkey and kept the right teeth. After half a year, the right side of the monkey's tooth developed normally, but the left side of the monkey's tooth has shrunk. This experiment proves that the brain will degenerate and shrink if it is not stimulated.
When people chew hard objects or chew faster, the cerebral blood flow increases obviously, and the difference between the cerebral blood flow of the elderly with teeth and those without teeth can be 30%. Good chewing function can ensure the blood supply to the brain and maintain the normal thinking activities of the brain.
Therefore, it is best to prepare some hard food on the dining table, and don't let the gums be too relaxed, so as to activate brain cells and prevent them from aging and degenerating prematurely because of laziness. For those people whose teeth are not perfect, or those who wolfed down their meals before chewing them, they should chew slowly, consciously increase the intensity of chewing, or chew gum, which can also achieve the purpose of strengthening the brain.
To tell the truth, there is really nothing that can improve IQ, otherwise everyone will not be Einstein! So don't believe those deceptive advertisements. We must use more brains and solve more mathematical and logical problems in order to improve the brain's reaction speed. Eating more walnuts, drinking more milk and getting enough sleep are good for the brain! !
