Can I eat crab during the fourth month of pregnancy?

Pregnant women can generally eat crab during the fourth month of pregnancy, but only in small amounts. The detailed explanation is as follows:

Crab is high in protein and rich in nutrients. Eating it in moderation can help supplement essential nutrients needed by the body. However, excessive consumption may increase the risk of threatened miscarriage. It's also important to note that only fresh crabs should be consumed—dead crabs must be avoided. When preparing crab, steaming is recommended, as this method preserves its nutritional value and reduces digestive discomfort that may result from richer cooking methods such as braising or deep-frying. Crab is considered a cold-natured food, and consuming too much may cause gastrointestinal discomfort. To counteract its cold nature, it is advisable to consume it with a ginger-vinegar dipping sauce.

Since crab is a type of seafood, pregnant women who are allergic to seafood should avoid eating it during the fourth month of pregnancy to prevent allergic reactions, which could lead to symptoms such as skin redness, swelling, itching, or difficulty breathing. In severe cases where the mother experiences breathing difficulties, the fetus may suffer from intrauterine oxygen deprivation, potentially affecting fetal health.
