Maternal fish and shellfish intake and pregnancy outcomes: A prospective cohort study in Brittany, France

Recommendations about risks and benefits of seafood intake during pregnancy have been published in the last decade, but the specific health effects of the different categories of seafood remain unknown. Fish and shellfish may differ according to their fatty acid content and their concentration of chemical pollutants and toxins. Not taking these particularities into account may result in underestimating of both the positive and negative effects of seafood on birth outcomesand partly explains inconsistent results on the subject.
