Can pregnant women eat seafood?
Pregnant women can eat seafood. In fact, seafood is considered a healthy food for pregnant women due to its role in supporting maternal health and fetal development. One of the most important nutrients found in seafood is omega-3 fatty acids. Omega-3 is essential for brain development, cognitive abilities in babies after birth, and reducing various pregnancy complications.
Various marine foods also contain vitamins, minerals, and proteins needed for fetal development and maternal health. However, pregnant women should not consume too many seafood products. Some types of seafood from the ocean contain mercury in small amounts. If pregnant women eat seafood high in mercury excessively, the mercury may be carried into the placenta and disrupt fetal development.
Risks of eating too much seafood during pregnancy
Healthy Children states that mercury will not cause harmful side effects for most people, especially those who are not pregnant. However, mercury exposure during pregnancy may increase various risks for the fetus.
- Nervous system or brain damage
- Impaired cognitive development
- Reduced hearing ability
- Seafood high in mercury typically includes large fish such as tuna, swordfish, tilefish, and king mackerel
However, this doesn't mean pregnant women should completely avoid seafood. Pregnant women can choose fish with lower mercury content, such as salmon, mackerel, and sardines. Consult your doctor about safe seafood portions during pregnancy.
