folic acid supplementation in the 1 th month of pregnancy can prevent anemia, premature delivery and fetal malformation, which is especially important in the early pregnancy, because early pregnancy is the key to the development of fetal nervous organs. Pregnant mothers should often eat foods rich in folic acid, such as bread, noodles, white rice and flour, as well as beef liver, spinach, asparagus, beans, apples, oranges and so on. In addition to food supplements, folic acid tablets can also be taken orally to ensure the daily folic acid needs.

In the second month of pregnancy, some expectant mothers will find that their gums will bleed when brushing their teeth. Appropriate vitamin C supplementation can alleviate the gum bleeding. At the same time, it can help improve the body's resistance and prevent dental diseases. Vitamin C in life comes from fresh fruits and vegetables, such as green pepper, cauliflower, cabbage, tomato, cucumber, spinach, lemon, strawberry and apple.

For expectant mothers who are troubled by pregnancy vomiting, vitamin B6 is the bane of pregnancy vomiting. Vitamin VB6 has the highest content in maltose. Eating 1-2 spoonfuls of maltose every day can not only inhibit vomiting during pregnancy, but also make pregnant women energetic. Foods rich in vitamin B6 include bananas, potatoes, soybeans, carrots, walnuts, peanuts, spinach and other plant foods. There are more lean meat, chicken, eggs and fish in animal foods.

In the third month of pregnancy, magnesium is not only vital to the health of fetal muscles, but also contributes to the normal development of bones. Recent research shows that the amount of magnesium intake in the first three months of pregnancy is related to the height, weight and head circumference of newborns. Magnesium is easily found in salad oil, green leafy vegetables, nuts, soybeans, pumpkins, melons, sunflower seeds and whole wheat foods. In addition, magnesium is also good for the recovery of mother's uterine muscles.

The whole process of fetal development needs vitamin A, which can ensure the health of fetal skin, gastrointestinal tract and lungs. In the first three months of pregnancy, the fetus can't store vitamin A by itself, so the pregnant mother must supply enough. Sweet potato, pumpkin, spinach and mango all contain a lot of VA.
