Pregnant women can eat clams during pregnancy. Clams are shellfish, which are rich in nutrients such as protein, calcium, iron, phosphorus and many kinds of vitamins, which can timely supplement the needs of pregnant women and their fetuses for nutrients. In addition, the meat of clams can have a certain diuretic and decongestant effect, especially for pregnant women in the edema period. However, pregnant women in early pregnancy and those who are allergic to seafood should avoid eating them to prevent allergic reactions that may affect their health. When choosing clams, you should buy them from the regular shopping malls to prevent infections due to unclean and unhygienic clams, and you should not consume too much clams because they are cold foods and too much of them will have a negative impact on the fetus. If pregnant women experience symptoms of discomfort after eating clams, they should terminate immediately and go to the hospital for examination, especially in early pregnancy.
