Children eating organic fruits and vegetables had concentration of esticide metabolites six times lower, than children eating conventaional produce, a University of Washington study found when they analyzed pesticide breakdown products (metabolites) in pre-school aged children. The study compared metabolite concentrations of organophosphorus (OP) pesticides (a class of insecticides that disrupt the nervous system) in the urine of 39 urban and suburban children aged 2 to 4 years. The researchers` findings point to a relatively simple way for parents to reduce their children`s chemical loads--serve organic produce.
