Vitamin E During fetal growth, pregnant women need to consume more vitamin E. It is now considered that vitamin E is involved in the metabolism of the body and certain cells and is related to the growth and development of the fetus. Foods rich in vitamin E: various green leafy vegetables, vegetable oils, grain germs, etc. Vitamin D Vitamin D deficiency during pregnancy can affect fetal bone development, can also lead to neonatal hypocalcemia, infant teeth and skeletal dysplasia and maternal osteomalacia. Like vitamin A, excessive intake of vitamin D by pregnant women can lead to poisoning. Therefore, it is recommended that the daily vitamin D intake of pregnant women be 5 micrograms in the early pregnancy period and 10 micrograms in the middle and late period. Foods rich in vitamin D: cod liver oil, egg yolk, milk, liver. Vitamin B6 Studies have shown that vitamin B6 can be delivered to the fetus from the mother as pyridoxine, and these substances are converted to pyridoxal phosphate in the fetus. Pyridoxal phosphate is involved in nucleic acid metabolism and protein synthesis. The amount of vitamin B6 required by pregnant women increases, and therefore the supply of vitamin B6 to pregnant women should be increased. Foods rich in vitamin B6 (pyridoxine): cereals, beans, egg yolk, meat, fish, milk, yeast. Vitamin C Vitamin C, also known as ascorbic acid, promotes the growth of the fetus. During pregnancy, the fetus obtains a large amount of vitamin C from the mother to maintain the normal development of the bones, teeth, and functions of the hematopoietic system, so that the content of vitamin C in the maternal plasma gradually decreases. Vitamin C through the placenta is an active transport process, so the level of vitamin C in fetal blood is 2 to 4 times higher than the mother's body. The level of maternal vitamin C is 50% lower than that of non-pregnant women. The decomposition rate of vitamin C in the fetus is relatively high, so vitamin C supplementation should be appropriately increased. If pregnant women lack vitamin C and are prone to anemia and bleeding, they can also cause premature labor and miscarriage. It is recommended that pregnant women receive 100 mg daily during the first trimester and 130 mg daily during the second trimester and third trimester. Foods rich in vitamin C (ascorbic acid): wild jujube, hawthorn, citrus, grapefruit, strawberry, pepper, rape, cabbage, garlic, cauliflower, tomatoes and so on. Vitamin B1 Vitamin B1 plays an important role as a coenzyme during energy metabolism and conversion of glucose to fat, and it plays an important role in the conduction of peripheral nerves. Vitamin B1 deficiency is prone to beriberi, mainly manifested as abnormalities in the nervous system and circulatory system. When pregnant women lack B1, they do not have obvious manifestations themselves, but they can cause fetal congenital beriberi. The recommended daily intake of vitamin B1 for pregnant women is 1.5 mg.
