In people's minds, tea has a lot of effects, such as refreshing, diuretic, Jieshu, etc. Modern research also shows that tea contains trace elements such as iron, zinc, manganese. Therefore, some people believe that maternal and lactating women should drink more tea, thinking that this is conducive to the development of the fetus or baby. In fact, there are many disadvantages for pregnant women to drink tea. Tea contains caffeine, which has toxic effects on the fetus and may affect fetal development. The study concluded that women’s ability to clear body during pregnancy is weakened. Long-term drinking of strong tea can cause caffeine accumulation and enter the fetus through the normal placental barrier, causing toxic effects on the fetus and causing intrauterine growth retardation and birth weight loss. Can also lead to congenital malformations. Caffeine is also a stimulant that is not conducive to maternal rest and sleep. Tea also contains another active ingredient, theophylline. Theophylline will produce a strong diuretic effect, will increase pregnant women's heart, kidney burden, easy to induce complications such as pregnancy poisoning, is not conducive to maternal and fetal health. There is a large amount of tannic acid in tea, which can be combined with iron to form insoluble substances, thus hindering the absorption of iron in the intestine. Although tea contains more iron, it is not easy to absorb and use it. Pregnant women have already had varying degrees of anemia. Pregnant women can easily aggravate this anemia by drinking tea, and it also causes the fetus to have a reduced iron reserve, which makes the baby after birth more susceptible to iron deficiency anemia.
