Vitamins can do that?

NEW YORK (Reuters Health) - Women who take multivitamins before and during pregnancy apparently reduce the chances that their offspring will develop certain types of childhood tumors, researchers report.

The study shows a 36% reduction in childhood leukemia and a 47% drop in neuroblastoma -- decreases in other childhood brain tumors as well. It's all very interesting and one more reason to feel guilty if you were tossing your cookies through the first trimester and couldn't keep crackers down, much less prenatal vitamins.
