Figuring out the right amount, and types, of fish to eat during
pregnancy can feel like yet another tricky decision meant to
test a conscientious mom-to-be. Much ado has been made of the
omega-3 fatty acids in fish that appear to promote healthy
development of the fetal brain. Research that gets a lot of
attention in certain corners of the Web suggests that kids born
to mothers who had more fish-derived omega-3s during pregnancy
fare better than the kids whose moms didn't. The reported
benefits associated with omega-3s include fewer behavior
problems, better verbal skills, and even higher IQs. So it's
hardly a shock that the meticulous mommy set has taken an
interest in seafood. At the same time, many expectant mothers
are perplexed by the toxins conundrum. Mercury, which can harm
the fetus's developing nervous system, is found in at least
trace amounts in nearly all seafood and at far greater levels in
