Just one week on a diet composed mostly (but not entirely) of organic foods can reduce adults’ exposure to pesticides by an astonishing 90 percent, according to a study conducted by researchers from RMIT University in Australia and published in the journal Environmental Research on April 29.
Lead researcher Dr. Liza Oates said, “Our results show that people who switch to eating mainly organic food for just one week can dramatically reduce their exposure to pesticides, demonstrating that an organic diet has a key role to play in a precautionary approach to reducing pesticide exposure.”
Neurotoxin Exposure Plummets
Although some studies have estimated the effect of organic diets on body burden of pesticides in children, the new study is the first published research on the same phenomenon in adults. The researchers randomly assigned 13 adults to eat a diet composed of at least 80 percent organic food or at least 80 percent “conventional” food (produced using pesticides, synthetic fertilizers and genetically modified organisms). After seven days, all participants were switched to the other diet for another week. Urine samples were taken the day after the conclusion of each diet intervention.
“Pesticide exposure in Australian adults is mainly through their diets, but there are other sources of exposure, so we wanted to find out the difference going organic could make,” Dr. Oates said.
Participants’ urine was tested for six different chemicals in the family known as dialkylphosphates (DAPs), which are produced as the body attempts to break down organophosphate pesticides.
