How Metals in Food Affect Your Child's Behavior
April 14, 2009
According to a lead researcher in the field, the contamination of food with certain metals needs to be urgently addressed in light of growing evidence linking trace metals to behavioral problems.
It has long been known that excessive amounts of any metal could be potentially dangerous, but there is now also strong evidence that even tiny amounts of some metals can contribute to aggressive or antisocial behavior, says Neil Ward, a professor of chemistry at the UK’s University of Surrey.
Lead has been linked to antisocial behavior, partly because it contributes to nutrient depletion. Aluminum has also been linked to antisocial behavior, as it competes for the binding sites of biochemical receptors of other metal ions, such as iron and zinc.
