An organic diet can quickly reduce the amount of glyphosate in the body after just six days, a new peer-reviewed study found.
The study, published this week in the Journal of Environmental Research and funded by Friends of the Earth, tracked levels of glyphosate, a common herbicide and main ingredient, in Monsanto's Roundup weed killers after participants switched to an organic diet.
Scientists analyzed urine samples from four racially and geographically diverse American families for five days on a non-organic diet and five days on an organic diet with a total of 16 participants and 158 urine samples.
They found that glyphosate levels in urine samples decreased by 70 percent within six days, while levels of aminomethylphosphonic acid, the chemical that breaks down glyphosate, decreased by 77 percent.
On a non-organic diet, the researchers found glyphosate in 100 percent of participants, including children aged four and over, and found that the average glyphosate level in children was about five times higher than in adults.
It builds on similar research, including a 2019 study examining the positive effects of organic foods on glyphosate exposure, and concludes that for most people, the foods they eat are the first Line exposed to the chemical.
Despite the small sample, the results are described as "abnormal" due to the short period in which the organic diet was effective.
"It is noteworthy that the levels of this toxic pesticide have dropped so dramatically in less than a week. Given our results and related studies of how an organic diet quickly reduces pesticide exposure, we can expect similar glyphosate reductions in most Americans when they switch to an organic diet, ”said study co-author and senior scientist at Friends of the Earth, Kendra Klein.
Organic nutrition has been associated with decreased glyphosate exposure.
"The reductions in glyphosate and AMPA levels were rapid and fell to baseline within three days," the report concluded. “This study shows that diet is a major source of exposure to glyphosate and that switching to an organic diet is an effective way to reduce the body's exposure to glyphosate and its major metabolite, AMPA.
"This research complements a growing body of literature indicating that an organic diet can reduce exposure to a range of pesticides in children and adults."
Glyphosate is used extensively in the United States and around the world for genetically engineered corn and soy in various non-organic arable crops, as well as in landscaping and home gardens.
Klein said, "We urgently need our elected leaders to make healthy organic food the norm for all by adopting guidelines that will help farmers move from pesticide-intensive to organic farming."
Another co-author, Sharyle Patton, said, "Research shows that color communities are at higher risk of serious complications and death from coronavirus because they are already more likely to suffer from diet-related diseases. More than ever, we need public policies to ensure that all communities have access to healthy organic food. "
The study was conducted by scientists from Friends of the Earth, the Health Research Institute, and the Commonweal Institute.
The study didn't look at the health effects of glyphosate, but research has linked the chemical to a range of health problems. Glyphosate is classified as a "Probable Human Carcinogen" by the World Health Organization and has been linked to high rates of kidney disease in agricultural communities and endocrine disorders.
A series of high-profile lawsuits in 2019 linked non-Hodgkin lymphoma to the use of Roundup, resulting in over $ 180 million in payouts, with thousands more pending.
