Infant brain development is the most important organ in baby's development, which directly affects the baby's intelligence and other aspects. Therefore, parents must pay attention to the baby's brain development. So, when is the fetal brain development? Eating these during pregna

The fetus's brain nervous system begins to develop from the 5th and 6th weeks of pregnancy, and it is not until the 8th week of healing of the nerve tube is completed. That is to say, after the embryo implants, the nerve cells begin to differentiate, and then various nerve cells are produced to move and combine with the synaptic . At the 8th week of pregnancy, the nerve tubes gradually heal, but the development of the entire nervous system will continue until the end of the pregnancy, and it will not reach 97% maturity within 3 years of birth.

5 foods that harm the fetal brain

1, oversalty food

0 Oversalty foods will not only cause hypertension , arteriosclerosis and other diseases, but also damage the arterial blood vessels, affect the blood supply of brain tissue, causing ischemia and hypoxia of brain cells , leading to memory loss and mental dullness.

The amount of salt required by the human body is less than 7 grams per day for adults and less than 4 grams per day for children. In daily life, parents should give their children less foods containing more salt, such as pickles, pickles, bacon, bean paste, etc.

2. Foods containing a lot of MSG

Medical research shows that if pregnant women eat MSG frequently in the late stage of pregnancy, it will cause zinc deficiency in the fetus. Children under the age of one year may cause brain cell necrosis. The World Health Organization proposes: Adults should not consume more than 4 grams of MSG every day, and pregnant women and children under the age of one year are fasted for MSG. Even if the child is older, try to give the child less food containing MSG.

3. Foods containing peroxide lipid

peroxide lipid will cause premature brain aging or dementia, which directly damages brain development. Bacon, smoked fish and other foods that have been fryed at oil temperatures above 200 degrees or exposed to the sun for a long time contain more peroxide lipids, and parents should give them less to their children.

4, lead-containing food

Medical research shows that lead kills brain cells and damages the brain. Popcorn, pineapple eggs, beer, etc. contain more lead, so parents should give their children less.

5, aluminum-containing food

Frequently give children foods with high aluminum content, which will cause memory loss, slow reactions, and even lead to dementia. Therefore, it is best for parents not to let their children eat foods with high aluminum content such as fried dough sticks and oil cakes.

For the fetus brain development, expectant mothers should pay more attention to the above foods.

Factors of fetal brain development

The intelligence of each family's northern nose grows differently, so what causes the difference. First of all, the intelligence level of father and mother largely determines Beibi's intelligence, and we can't do anything about this.

You can try to properly stimulate the North nose when the North nose is still in your stomach, so that its brain development is more complete and smarter. However, the brain development of the northern nose will often become slow due to external influences.

1. If the father is a close relative than the mother, the northern nose brain may develop slowly, and it will not be too clever after birth.

2. If the mother goes out without holding an umbrella, the northern nose will be stimulated by ultraviolet rays, which will also affect the brain development of the northern nose.

3, mommy folic acid, protein insufficient supplementation, so the brain development of the northern nose will not be normal, but will be appropriately delayed in the northern nose brain.

4. If the mother is in poor health or accidentally takes medicine that she shouldn't take, then our northern nose will suffer
