We know that during pregnancy, all the nutrients needed for the growth and development of the fetus come from the mother-to-be, so it can be said that what the mother-to-be eats is what the fetus eats. Therefore, during the whole pregnancy, the mother must pay attention to her own diet, and try to eat as little as possible or not eat the food that is not good for the development of the baby.

MuMu received a call from her college friend XiaoFen early in the morning, who was pregnant and wanted to tell her the good news. The first thing I want to say is that I've been reading books about pregnancy diets for the past few days, and I've learned that it's good for a pregnant woman to eat a lot of walnuts for her baby's brain development. It just so happens that walnuts are abundant in Mu Mu's hometown, so she wants her to help buy some walnuts to stock up and eat them as a snack during her pregnancy, in preparation for having a smart baby.

That's right, there are many benefits to eating more walnuts during pregnancy. Because walnuts are rich in vitamin E, linolenic acid and phospholipids, etc., which vitamin E can improve blood circulation, enhance cellular vitality, linolenic acid can promote the brain development of the fetus baby, phospholipids have the role of enhancing cellular vitality, can enhance the mother-to-be's body resistance.

There are some foods that are beneficial to the mother-to-be during pregnancy, but it is also important to note that there are some foods that can harm the brain of the fetus, and the mother-to-be should try to eat as little as possible.

01. Foods containing lead or aluminum

Lead affects the brain development of the fetus, and if a pregnant woman consumes foods containing high levels of aluminum during her pregnancy, not only is it easy to cause the fetus to lose its memory after birth, but it will also cause the baby to have a low level of intelligence. Therefore, during pregnancy, high lead content and high aluminum content of food, the mother-to-be is best not to eat often oh. For example: loose eggs, popcorn, doughnuts, oil cake, etc., these foods contain more aluminum.

02. Foods containing lipid peroxide

Mothers-to-be should try to avoid foods containing lipid peroxide, because lipid peroxide can lead to premature aging of the brain or dementia, which is directly detrimental to the development of the brain, so during pregnancy, mothers-to-be should try to eat as little as possible of this type of food. For example: bacon, smoked fish, etc. had been in the oil temperature of 200 degrees above the frying or long exposure to the sun in the food, contains more lipid peroxide, this kind of food, expectant mothers to stay away from.

03. Foods containing MSG

If the mother-to-be in pregnancy often eat MSG will be easy to cause fetal baby zinc deficiency. Zinc is a key element in promoting growth and development, and if the baby is deficient in zinc, it will lead to developmental delays and affect the development of the baby's brain quality. Therefore, the mother-to-be during pregnancy, should try to eat less food containing MSG, even after the baby is born, breastfeeding period, should also try to eat less oh.

04. too salty food

The human need for salt, adults in the 7 grams per day. Excessive consumption of too salty food, salt intake more than the amount of human needs, will affect the blood supply of brain tissue. Therefore, expectant mothers should eat less food containing more salt during pregnancy. In our daily life, foods that contain more salt, for example, are salted vegetables, squash, salted fish, salted meat and so on.

Dill pickles

Of course, the mother-to-be should eat less food that is not good for her baby's intellectual development during pregnancy. At the same time, in several key periods of fetal brain development, the mother-to-be to eat more to promote fetal brain development of the baby food Oh.

Fetal baby brain development requires a variety of nutrients, mothers-to-be should pay attention to the intake of these nutrients:

Protein: involved in the composition of the cell is one of the main raw materials of the brain cells

Lipids: is the development of brain nerve fibers indispensable substances;

Carbohydrates: is the metabolism of the brain cells of the material base;

In a variety of foods, the brain development plays an important role in many foods, the following to the mother-to-be reference.

Increase brain cells: walnuts, peanuts, pine nuts;

Increase the volume of brain cells: fish, lean meat, eggs, animal liver;

Enable the brain cells to establish a wide range of connections: foods rich in vitamins and trace elements.

The nutritional status of the mother-to-be has a great impact on the fetal baby's brain development, especially during several critical periods of fetal baby's brain development. The mother-to-be should eat less food that is not favorable to the brain development of the fetus, and eat more food that will help the fetus to develop intellectually.
