Researchers at the University of Connecticut has found that some fish are high in a certain chemical that's vital to brain and nerve cell growth in fetuses and newborns.
Babies can't make enough docahexanoic acid -- or DHA -- a fatty acid that helps the brain develop. They must take whatever their mothers give them, either through the umbilical cord or by breast-feeding after they're born. And note that baby formula isn't fortified with DHA.
Women who eat cold-water species, like salmon, trout, sardines and tuna, give their babies a better chance at maximizing brain tissue development, the research found.. Other fish high in the chemical are herring, swordfish and mackerel.
