What Guidelines Say

i

Consuming 8-12 ounces of low-mercury fish weekly during pregnancy supports fetal development.

Read more details

Guidelines from the FDA and ACOG emphasize that fish provides essential nutrients like omega-3 fatty acids, protein, and iodine for fetal development. However, selection is critical due to methylmercury, a heavy metal that can impair a developing baby's brain and nervous system. The 'Best Choices' list includes options low in mercury that can be consumed in 2 to 3 servings per week. Conversely, certain large, long-lived predatory fish contain high mercury levels and are recommended to be avoided entirely. Additionally, all seafood must be cooked to an internal temperature of 145°F to eliminate risks from parasites and bacteria such as Listeria monocytogenes. Raw or undercooked preparations, including sushi and refrigerated smoked seafood, are generally advised against due to increased vulnerability to foodborne illnesses during pregnancy.
