It is usually not recommended to consume crab while breastfeeding. However, if crab has been consumed, it is best to suspend breastfeeding and wait 24 hours before breastfeeding. The nutritional value of crab is relatively high, but it is cold, so it is not suitable for postpartum women. In addition, crab contains parasites in its body during the growth process, and if it is not cooked properly, bacteria and parasites cannot be killed, so it is not good for the health of breast milk after consumption. However, if a breastfeeding woman has already eaten crab, she can dilute the cold nature of her body by drinking a lot of water to speed up her body metabolism. You can also eat warm foods such as brown sugar ginger tea and beef soup to relieve the coldness and wait 24 hours before breastfeeding to reduce the possibility of causing diarrhea and allergies to the baby. In addition, breastfeeding women also need to ensure a balanced and nutritious diet, choosing fresh, seasonal ingredients is best, and can eat more high-protein foods to ensure sufficient milk.
