Consuming seafood while pregnant can help provide the mother and baby with needed nutrients. Fish and other seafood contain an oil called omega-3 DHA, which is crucial for babies to develop healthy brains. Aim to eat about two to three servings of cooked seafood weekly, ensuring the seafood is low in mercury. High levels of mercury can hinder a baby's development and may cause damage. Many specialists advise pregnant women to avoid shrimp and shellfish. Consult your healthcare provider for details regarding your individual needs and what is right for you.
