Making the switch to an organic diet could quickly reduce the body’s level of certain pesticides, according to a new study by the Center for Environmental Research and Children’s Health (CERCH) at UC Berkeley’s School of Public Health.
The study was led by CERCH Associate Director Asa Bradman and involved researchers collecting the urine samples of 20 children from urban communities in Oakland, Calif., and 20 children from agricultural communities in Salinas, Calif., over 16 consecutive days. During this time, researchers alternated the children’s diets between “conventional” and organic.
The study was published in the October issue of the journal Environmental Health Perspective. Researchers tested samples for metabolites - components of the body’s metabolizing process, which reflect the body’s exposure to certain pesticides.
Among the six most frequently detected pesticides, two decreased by nearly 50 percent when children were on the organic diet, and levels of a common herbicide fell by 25 percent. Three other frequently detected pesticides were not significantly lower when on the organic diet.
