Generally speaking, pregnant women can eat swimming crabs, but it is not recommended to consume them in large quantities. The detailed explanation is as follows:

Swimming crab contains abundant high-quality protein, which can provide necessary nutrients for maternal metabolism and fetal growth and development, aiding in the formation of fetal tissues and organs. It is also rich in minerals such as calcium, phosphorus, and iron. Calcium supports fetal bone and tooth development, while iron helps prevent iron-deficiency anemia during pregnancy. Additionally, various vitamins in swimming crab can help meet increased nutritional needs during pregnancy. Eating moderate amounts of swimming crab can be beneficial to both the pregnant woman and the fetus.

When consuming swimming crab, be sure to choose live, fresh crabs and cook them thoroughly to avoid bacterial or parasitic infection. Each serving should not be excessive—just a moderate amount—to prevent placing extra strain on digestion or causing discomfort. Pregnant women who are allergic to seafood or have conditions such as spleen and stomach deficiency-cold or threatened miscarriage should avoid eating swimming crab. After consumption, pay attention to any physical reactions. If symptoms such as abdominal pain or diarrhea occur, seek medical attention promptly.
