- Organic diet intervention significantly reduces urinary pesticide levels in U.S. children and adults
"In this paper, we address existing data gaps by investigating whether an organic diet intervention reduced urinary levels of OPs, pyrethroids, neonicotinoids, fungicides, and one herbicide among adults and children from four geographically and racially diverse families in the United States."
"During days one through five, study participants were asked to follow their normal conventional diet (conventional phase). During days six through eleven, all family members were provided with certified organic food while at home, work, school, or daycare, including all beverages other than water, all food categories, and oils, condiments, and spices (organic phase). After the participants collected the first morning void urine sample on day twelve, they could choose to eat either organic or conventional food. Organic food was provided to families in two ways: 1) Participants were asked to compile a list of all groceries they would need for six days, and research assistants purchased organic foods from this list and delivered the groceries to the participants’ homes for their use, and, 2) dinners were prepared with all organic foods by a licensed chef or caterer and delivered to study participants by the research assistants. All organic foods for the six-day period were provided free of charge to the families."
"We observed significant reductions in urinary levels of thirteen pesticide metabolites and parent compounds representing OP, neonicotinoid, and pyrethroid insecticides and the herbicide 2,4-D following the introduction of an organic diet. The greatest reductions were observed for clothianidin (−82.7%; 95% confidence interval [95% CI]: −86.6%, −77.6%; p < 0.01), malathion dicarboxylic acid (MDA), a metabolite of malathion (−95.0%; 95% CI: −97.0%, −91.8%; p < 0.01), and 3,5,6-trichlor-2-pyridinol (TCPy), a metabolite of chlorpyrifos (−60.7%; 95% CI: −69.6%, −49.2%; p < 0.01). Metabolites or parent compounds of the fungicides boscalid, iprodione, and thiabendazole and the neonicotinoid insecticide imidacloprid were not detected among participants in our study."
