What are the factors determining IQ?

Influencing factors 1: heredity

Generally speaking, if parents have high IQ, their children's IQ will not be low.

There is a theory that the farther the blood relationship between parents is, the higher the IQ of children; The fact that hybrids are beautiful and clever is a proof that this theory is often cited. Of course, marriages between different races and nationalities can also produce smart children. However, consanguineous marriage is the bane of bearing children with dementia, and the concept of "marriage and childbirth in the same village" and other local materials should not be advocated.

Influencing factor 2: 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, which 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. Nutritionists from Cambridge University in England tested the IQ of more than 30 children aged 7-8, and compared them with the recipes in infancy. The results show that the IQ of breast-fed children is generally higher than that of children who eat milk substitutes, which is 10 on average. The secret is that breast milk contains many kinds of active substances that can promote children's brain development, especially a special amino acid called taurine, which can not only increase the number of brain cells, promote the differentiation and maturity of nerve cells, but also help the formation of nerve knots.

The content of taurine in breast milk is 10 times higher than that in milk.

Influencing factor 3: diet

Because nutrients are an indispensable material basis for baby's intelligence and brain development. Eating more brain food in daily life is good for your baby, and correcting bad eating habits can't be ignored.

Feeling of satiety: When eating, the blood vessels in the digestive tract dilate, the whole body blood is concentrated in the gastrointestinal tract, and even there is cerebral ischemia and hypoxia. If the baby eats too much, it is easy to cause cerebral ischemia for a long time, which is not conducive to brain development.

Dieting: Although eating too much will lead to premature aging of the brain, it does not mean that eating less is better. The development of brain and intelligence needs comprehensive nutrition. The lack of protein, nucleic acid, phospholipid and lecithin will reduce the number of brain cells and brain capacity, lead to the dysplasia of glial cells and nerve fibers, and cause mental retardation, so the baby's diet should be diversified.

Vegetarian: Some people don't eat meat, which leads to a decrease in fat intake. Unsaturated fatty acids, which account for 60% of brain cells, cannot be synthesized by human body and need food supplement. In particular, fish is rich in polyunsaturated fatty acid-hexenoic acid of liver phosphate, which is the highest fatty acid in human brain and is related to the growth of brain cells and the maintenance of normal physiological functions. Fish and shellfish are rich in taurine, which plays an important role in the development of brain nerves. Therefore, a balanced diet is an important condition for the healthy development of children.

Fried food: protein will not only lose its biological activity, but also mutate into harmful substances when it is coked at high temperature during cooking. It is easy to degrade cells, so it is not suitable for long-term consumption.

Influencing factor 4: weight

Children who weigh more than 20% of normal children will have low vision, hearing and ability to accept knowledge. In addition, many children are skinny, which is not conducive to the development of the brain, thus affecting the development of intelligence. Except a few of these children are caused by diseases, most of them are related to picky eaters and anorexia. At present, most one-child families like their children more or less. Many children often eat three meals a day abnormally, and snacks don't leave their mouths. Malnutrition is inevitable.

Influencing factor 5: environment

Children who live in a boring environment, such as abandoned babies, will not get maternal love and good education, and their IQ will be lower. According to the survey, the average IQ of such children at the age of 3 is only 60.5, while the average IQ of 3-year-olds with good environment is 9 1.8.

Influencing factor 6: drugs

Some drugs will affect children's intelligence. For example, taking antiepileptic drugs for a long time will make its IQ low, and it will improve after stopping taking drugs for a few years.

Influencing factor seven: human physiological rhythm

Scientific research shows that from birth to the end of life, everyone's body has periodic changes in physical strength, emotion and intelligence, which is human physiological rhythm.

Influencing factor 8: Vitamin C intake level.

American nutritionists have tested more than 350 children and found that those whose blood contains more than 100 ml of vitamin C 1. 1 mg have an IQ of 5 points higher than the average. This is mainly because the neural tubes responsible for delivering nutrients to the brain in human brain cells are easily blocked and thinned, resulting in lack of nutrition and decreased function of the brain. Vitamin c can keep the neural tube unobstructed, thus ensuring the nutritional supply of the brain.

Influencing factor 9: exercise

Research shows that students who insist on exercising for 20 minutes every day, such as running and aerobics, have significantly better academic performance than those who are lazy in sports. Physical exercise can make the brain in the initial starting or relaxing state, and the imagination will be liberated from the shackles of various thinking and become more agile and creative.
