Women should not drink sweet wine during pregnancy because sweet wine, which is formed by fermenting glutinous rice as one of the raw materials, contains certain alcohol components that can have adverse effects on pregnant women and fetuses, such as causing abnormal fetal development. The main hazards of consuming sweet wine for pregnant women are as follows: 1. If a pregnant woman ingests alcohol, it may be absorbed into the fetus through the placenta, easily affecting the development of the fetus’ brain and other organs and leading to fetal malformations. 2. Drinking sweet wine for pregnant women will also increase the burden on the body. The woman must not consume alcohol during pregnancy, but also pay attention to a light diet.
