The debate over autism continues. A two-year-old study about the link between breastmilk and the developmental disorder is gaining attention again after the university where it was conducted re-published the results on its website. In 2007, UCSF's Dr. Michael Merzenich introduced rats to the same levels of environmental toxins like PCB and PBDE found in breastmilk and saw significant deterioration of the brain.

Dr. Merzenich suggested that women exposed to high levels of environmental toxins should reconsider giving their tots breastmilk due to the toxins' ability to exacerbate brain disorders. No such studies have been conducted in humans at this point, but the research does have people talking. Do such findings make you reconsider nursing?
