Even before we are born, we need key nutrients found in fish and seafood. That’s according to the current Dietary Guidelines for Americans 2020-2025, which advises pregnant women to consume 8 to 12 ounces of a variety of seafood each week. Besides being an excellent source of baby-building protein, seafood provides nutrients such as omega-3 fats and iodine which are important to baby’s brain and mental development.
