The soup made of crab and turtle has the effect of activating blood and removing blood stasis, especially crab claws and turtle nails have obvious abortifacient effects, so it is not recommended to drink. In addition, strong tea, coffee, cola, these drinks contain more or less caffeine or colaine, this part of the substance has a stimulating effect on the central nervous system, during pregnancy can only drink a small amount, drinking too much will cause harm to the fetus. There are also cold drinks and sodas pregnant women should also drink less, because women after pregnancy gastrointestinal function is weakened, too cold food will make the gastrointestinal blood vessels suddenly contracted, digestive function is weakened and diarrhea, abdominal pain and other symptoms. Soda can deplete the iron in the mother-to-be’s body, which can lead to anemia and affect the baby’s development.
