I saw this on the internet & thought I'd pass it along.....

Eating fish does contribute to your intelligence, particularly before and 
just after you're born. 

A researcher 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 -- 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.
