Early BPA Exposure Linked to Later Food Intolerance

October 30, 2014 2:00 pm | by Federation of American Societies for Experimental Biology | Comments

Scientists have shown that there is a link between perinatal exposure to BPA at low doses and the risk of developing food intolerance in later life. This research, involving rats, suggests that early life exposure at a dose significantly below the current human safety limit set by the FDA affects developing immune systems, predisposing offspring to food intolerance in adulthood.
