Milk tea can remove grease, help digestion, diuretic and detoxification, and eliminate fatigue, but it is clinically recommended that pregnant women drink as little milk tea as possible because milk tea can cause the following hazards to pregnant women: 1, affect fetal development: milk tea contains very high levels of trans fatty acids (creamer, phytate, etc.) chemical additives. Some studies have found that the fetus can passively ingest TFA through the placenta, which increases the likelihood of essential fatty acid deficiency and thus affects its growth and development; 2, increase the cardiovascular risk of pregnant women: TFA in milk tea also increases the viscosity and cohesion of human blood, which can easily lead to the formation of blood clots and increase the risk of cardiovascular disease in pregnant women; 3, induce gestational diabetes: milk tea usually contains a lot of sugar. It is not recommended to consume foods high in sugar during pregnancy, and if the sugar in the body is too high, it may increase the risk of gestational diabetes in pregnant women; 4, excitement of the uterus: milk tea contains a certain amount of caffeine, which may cause excitement in the uterus of pregnant women, stimulate the fetus to increase fetal movement, and even lead to contraction of the smooth muscle of the uterus, which may lead to the occurrence of accidents. Therefore, pregnant women are clinically advised to drink milk tea as little as possible.
