Pregnancy is a crucial period during which a woman’s nutritional choices significantly impact her health and the developing foetus. Seafood is a valuable source of essential nutrients such as omega-3 fatty acids, proteins, and minerals which are essential for foetal growth. However, concerns about contaminants such as mercury have led to apprehensions about the safety of consuming seafood during pregnancy. In India, where seafood is a dietary staple, expectant mothers need to make informed choices from selecting low-mercury fish to understanding local sourcing to ensure a balance between nutrition while safeguarding against potential risks.
Safety Guidelines for Seafood Consumption in Pregnancy
Choose low-mercury fish: Opt for varieties of fish that are low in mercury, such as shrimp, catfish, and salmon. These options provide essential nutrients without exposing the mother and the developing foetus to high levels of mercury, which can adversely affect the nervous system.
Limit high-mercury fish: Certain fish such as sharks, swordfish, and king mackerel, are known to have higher mercury levels. Pregnant women should limit the consumption of these fish to minimize the risk of mercury toxicity.
Cook seafood thoroughly: Proper cooking is crucial to eliminate harmful bacteria and parasites. Ensure that seafood is cooked thoroughly, reaching a safe internal temperature. Avoid raw or undercooked seafood to prevent the risk of foodborne illnesses.
Diversify seafood choices: Instead of relying on a single type of seafood, diversify your choices to reduce the risk of potential contaminants. This approach allows pregnant women to benefit from a variety of nutrients present in different seafood.
Be mindful of local advisories: Consider local guidelines and advisories regarding seafood consumption. Certain regions may have specific recommendations based on local contamination levels. Staying informed about these guidelines is crucial for making safe and informed choices.
Nutritional Benefits of Seafood during Pregnancy
Omega-3 fatty acids: Seafood, especially fatty fish like salmon, is rich in omega-3 fatty acids, which play an essential role in foetal brain and eye development. Including these in the diet can contribute to the overall cognitive development of the unborn child.
Protein for growth: Protein is an essential component for the growth of the developing foetus. Seafood provides high-quality protein, supporting the formation of tissues and organs in the developing baby.
Minerals and vitamins: Seafood is a natural source of various minerals and vitamins, including zinc, iodine, and vitamin D. These nutrients are vital for the proper development of the baby’s bones, immune system, and overall health.

Note: Use caution for fish caught in local rivers and streams that may have high mercury content; check with local authorities before consuming fish from these waters. It is essential to seek healthcare provider advice tailored to the individual health condition and dietary requirements during pregnancy.
How much seafood is recommended?
During pregnancy in India, it is generally recommended to consume less than 0.05 ppb of mercury and 2-3 servings of seafood per week. Opt for varieties rich in omega-3 fatty acids, such as salmon and shrimp. In the first trimester, focus on establishing a balanced diet with essential nutrients. As pregnancy progresses, consider incorporating DHA-rich fish for foetal brain development. It is essential to avoid high-mercury fish like sharks and limit tuna intake. Always prioritize a diverse and nutrient-rich diet to support both maternal and foetal well-being.
To summarize, seafood can be a valuable and nutritious part of a pregnant woman’s diet in India, provided certain precautions are taken. By choosing low-mercury options, cooking seafood thoroughly, and staying informed about local advisories, expectant mothers can enjoy the nutritional benefits without compromising their safety or that of their developing babies. Healthcare professionals need to educate pregnant women about making informed choices, ensuring a balance between the nutritional advantages of seafood and the potential risks associated with contaminants. Ultimately, a well-rounded and diverse diet during pregnancy contributes to the mother’s and growing child’s health and well-being.
