During pregnancy, pregnant women can eat crabs, but in moderation. Crabs are rich in nutrition, which can provide nutrition and promote fetal development. However, pregnant women should pay attention to moderate consumption to avoid symptoms such as abdominal pain and diarrhea. Choose fresh and tasteless crabs to avoid eating spoiled or polluted crabs, so as not to affect the health of yourself and your fetus. In short, pregnant women should pay attention to a reasonable diet and maintain a balanced nutrition.
