If pregnant women can drink 3 to 5 grams of tea a day, especially light black tea, it is of great benefit to strengthen heart and kidney function, promote blood circulation, help digestion, prevent pregnancy edema, and promote fetal growth and development. Different types of tea contain different ingredients, green tea is extremely rich in zinc, while the amount of zinc in the leachate of black tea is very small. Zinc plays an extremely important role in the normal growth and development of the fetus. Therefore, experts believe that pregnant women like to drink tea can drink black tea in moderation. However, if pregnant women drink too much tea and are too concentrated, especially drinking strong black tea, it will cause harm to the fetus. Tea contains 2% to 5% of caffeine and about 0.06 mg of caffeine per 500 ml of concentrated black tea.
Caffeine has excitatory effects. Drinking too much tea will stimulate the fetus to increase fetal movement, and even endanger the growth and development of the fetus. Surveys by Japanese experts have confirmed that pregnant women can lose weight if they drink 5 cups of black tea each day. Black tea contains tannic acid, and tannic acid can be combined with iron in pregnant women food to form a compound that cannot be absorbed by the body.
If pregnant women drink too much tea there is the possibility of anemia in pregnancy, the fetus may also have congenital iron deficiency anemia. Scientists conducted tests using ferric chloride solution as a source of iron. It was found that the absorption rate of iron in drinking water was 21.7%, while that of drinking strong tea was only 6.2%.
Drinking dark tea is good for pregnant women, but dark tea also contains tannic acid, which can also hinder the absorption of iron. How can a pregnant woman drink dark tea to achieve the maximum effect? ​​The fetus is beneficial without affecting the absorption of iron. Pregnant women can drink this light tea after an hour of a meal to resolve this contradiction.
Pregnant women who do not have tea habits are better off using vitamin C-rich beverages because vitamin C helps iron absorption and enhances the body's resistance to disease.
