There are many periods that women need to pay attention to after pregnancy, including many precautions for diet and daily life. Some women have a habit of drinking green tea before pregnancy, but some believe that drinking green tea can cause poor skin in the fetus. Does this statement have scientific validity? Does drinking green tea during pregnancy cause the fetus to turn black?
Firstly, drinking green tea after pregnancy does not necessarily cause the fetus to have darker skin. There is no necessary connection between the darker skin of the fetus after birth and drinking green tea, and this claim has no scientific basis. The occurrence of darker skin in infants is usually determined by genetic factors. In general, women who drink a small amount of green tea during pregnancy generally do not have a direct impact on various indicators of the fetus.
However, it is still not recommended for women to drink tea during pregnancy, especially fermented black tea and strong tea. Because tea contains caffeine, which has an excitatory effect and can affect the regular sleep schedule of pregnant women. Pregnant women with insomnia and poor rest will inevitably affect their own health, which is also detrimental to the development and growth of the fetus.
In addition, drinking strong tea from black tea contains tannic acid, which can react chemically with iron and potentially affect the absorption of iron in the body. If tannic acid reacts too much and inhibits the absorption of iron, it may easily cause anemia symptoms in pregnant women. Therefore, it is advisable not to mix fermented tea with strong tea and black tea.
