Pregnant women must supplement enough vitamins and minerals, especially in the first and third trimesters. In the first trimester, pregnant women have poor appetite because of various pregnancy reactions, while in the third trimester, due to the growth of the fetus, the stomach is squeezed, which leads to some pregnant mothers eating very little, so it is easy to lack nutrition in these two periods. Therefore, we can choose appropriate nutrients to make up for the shortage of complementary food, especially folic acid and other vitamins for pregnant women, which are essential for pregnant women and fetuses and should be supplemented by every expectant mother.

First, supplement nutrition in stages.

Early pregnancy (0~3 months)

Characteristics of (1): The secretion of progesterone in the first trimester is increased, the digestive function is affected, and early pregnancy reactions such as nausea, morning sickness and loss of appetite are prone to occur. This is also a critical period for the differentiation and formation of fetal neural tube, and pregnant women need to supplement nutrients that are helpful to the development of fetal nervous system in time.

(2) Key nutrition

Folic acid: preventing fetal nerve organ defects. Folic acid supplementation in pregnant women can effectively prevent qi and blood deficiency and ensure the normal development of fetal nervous organs.

② Vitamin C and vitamin B6: Vitamin C can effectively relieve gingival bleeding. In the second month of pregnancy, some pregnant women will bleed when brushing their teeth. Supplementing proper amount of vitamin C can reduce the occurrence of gingival bleeding. At the same time, it can also help pregnant women improve their physical resistance and prevent dental diseases. Vitamin B6 is the bane of morning sickness and can maintain the normal function of the nervous system. Supplementing proper amount of vitamin B6 can effectively relieve morning sickness.

Magnesium and vitamin A: It is very important for pregnant women to supplement enough magnesium for the development of fetal muscles and bones, and magnesium is also very helpful for the recovery of pregnant women's uterine muscles. Vitamin A is very important throughout pregnancy and plays an important role in maintaining the health of fetal skin, gastrointestinal tract and lungs. Especially in the first trimester, the fetus can't store vitamin A, so pregnant women should ensure adequate supply of vitamin A.

2, the second trimester (4~7 months)

(1) Features: In the second trimester, pregnant women's food intake will increase significantly, but they are prone to feel full. At the same time, the second trimester is also a period of rapid fetal development, which requires a lot of nutrients to help build a brand-new body.

(2) Key nutrition

① Zinc: Ensure the normal growth of the fetus. Pregnant women need to increase their zinc intake in the second trimester. If zinc is deficient, it will affect the healthy growth of the fetus in the uterus, and it is easy to cause the growth retardation of important organs such as the brain and heart of the fetus.

② Vitamin D and calcium: promote the development of fetal bones and teeth. Fetal bones and teeth grow very fast in the second trimester, which is a period of rapid calcification, and the demand for calcium increases sharply, so pregnant women need to strengthen supplementation.

③ Iron: Prevent deficiency of qi and blood. During this period, the nutritional needs of pregnant women and fetuses are soaring, and many pregnant women begin to be deficient in both qi and blood, so they usually need to pay attention to adequate iron intake.

3, the third trimester (8~ born)

(1) Features: Pregnant women have a strong appetite during this period, but the fetus in the body squeezes the stomach and intestines, resulting in insufficient nutrition for pregnant women. At this time, it is also the rapid growth period of the fetus, which requires a lot of nutrition intake.

(2) Key nutrition

In the third trimester, pregnant women and fetuses have great demand for various nutrients. It is necessary to supplement various vitamins, enough iron and calcium and enough water-soluble vitamins, especially vitamin B 1. If vitamin B 1 is lacking, it is easy to cause vomiting and fatigue in pregnant women, and even affect uterine contraction during delivery, leading to prolonged labor and difficult delivery. In short, during pregnancy, every kind of nutrition is very important for the health of pregnant women and fetuses. In the case of insufficient supplementation at ordinary times, you can choose to take a variety of vitamin and mineral tablets.

Vitamins play an important role in maintaining human health, especially during pregnancy, the nutrition of expectant mothers will directly affect the baby's development. To breed new life, they must provide sufficient nutrition to ensure the healthy growth of babies.
