Seafood consumption during pregnancy may be associated with better social–emotional, behavioural, and aggregate scores of development in the child, as well as potentially some aspects of cognitive development.

A suite of six newly published reviews from the Texas A&M Agriculture, Food and Nutrition Evidence Center found that seafood intake during pregnancy and childhood is likely associated with beneficial neurocognitive development outcomes in children.
 
The publications, a suite of systematic and scoping reviews of existing research, appear in the journals Advances in Nutrition and Environmental Research. They show that the developmental benefits of nutrient-rich seafood may outweigh possible harms—such as low birthweight or motor development issues—from potential exposure to contaminants in seafood including lead and mercury.
 
"Investigating growth and developmental outcomes related to seafood intake is challenging because seafood can contribute both essential nutrients like omega-3 fatty acids, for example, as well as hazardous contaminants like mercury or lead," said Maureen Spill, Ph.D., associate director of the Evidence Center and a researcher in the review suite.
 
The reviews offer insights into the National Academies of Sciences, Engineering and Medicine's initiative to provide an updated, holistic understanding of how seafood consumption affects child growth and development.
