1, eggs

Eggs contain many nutrients, such as protein, amino acids, calcium, iron, phosphorus and vitamins, which can improve the function of human nervous system, so eggs are a good brain-nourishing food.

Step 2: bananas

Bananas contain a lot of serotonin, which can stimulate the nervous system and promote the development of the brain. Therefore, expectant mothers eat more bananas during pregnancy, and the baby's brain will develop healthier.

3. Walnut

The development of the brain is inseparable from a substance called linoleic acid glyceride. Walnut contains a lot of linoleic acid and glyceride, so walnut has the function of nourishing brain. But the fat content in walnuts is also quite high, so expectant mothers should eat walnuts in moderation, otherwise they will get fat easily.

4. Apple

Zinc in apples is very helpful for improving brain memory and making brain thinking more active. Therefore, during pregnancy, if expectant mothers can eat more apples, it is also very beneficial to the baby's brain development.

It should be noted that pregnant women should not buy some health care products to take during pregnancy, because health care products may not be real "health care products" for the fetus, but may become killers that endanger the baby's health. Dietotherapy for pregnant women is the safest and most reliable method.
