Note: Yet again, the Omega 3's. Given the high amounts of toxins found in many fish, a good fish oil supplement is a good idea. One of the one's that I like that is easily available is from Norwegian Naturals. Best to take cod liver oil in the winter months to supplement vitamin D, and salmon oil in the summer months.
In a study of 135 mothers and their infants, researchers at Harvard Medical School in Boston found that mothers' fish consumption during pregnancy seemed to aid fetal brain development. Overall, the greater a woman's fish intake during the second trimester, the better her 6-month-old performed on a standard test of mental development.
On the other hand, when mothers had fairly high mercury levels -- as measured in hair samples -- their babies tended to have relatively poorer test scores.
