A new study claims an organic diet can significantly reduce pesticide levels, but the research doesn’t hold up.Published February 12 in the journalEnvironmental Research, the authors of the study tested pesticide levels in the urine of 16 study participants, before and after switching to an organic diet, and found pesticide levels decreased after the switch. But there’s more to the story.
The study primarily tested for the kinds of pesticides allowed in conventional agriculture, and not the pesticides allowed on organic farms. So what the study actually shows is fairly obvious: people won’t flush out what they aren’t eating.
The study also doesn’t say anything about whether there’s ahealth risk associated with conventional pesticide residues, since the mere presence of a chemical in urine isn’t necessarily an unhealthy or dangerous sign.
This study might be problematic, but it isn’t the first of its kind. In 2015, a Swedish organic grocery co-op sponsored a similar study with even less participants, a family of five who had switched from a diet of conventionally grown food to an all-organic one.
The results were the same: when the participants switched to eating organic, the levels of synthetic pesticides in their urine decreased. But, again, that’s because people who avoid conventionally grown food also consume lower levels of synthetic pesticides.
Much like this most recent study, the Swedish experiment didn’t test for organic-approved pesticides, which means it didn’t show that an organic diet actually decreased overall pesticide levels, only that an organic diet is associated with lower levels of one category of pesticide: synthetic.
It’s no secret that both organic and conventional farmers use pesticides but, for the most part, organic growers use natural pesticides rather than synthetic chemicals. Under federal law, natural pesticides are allowed in the USDA organic program, whereas most synthetic pesticides are not permitted. While many organic growers strive to use fewer pesticides overall, consistent with the guiding principles of organic agriculture, it would be inaccurate to describe organic food as pesticide-free.
Whether organic or conventional, the bottom line is that trace levels of pesticides on food don’t actually pose much of a health risk to eaters. Farmworkers and produce packers, on the other hand, do have a higher health risk because they’re exposed to pesticides more frequently and in higher doses.
Farmers have pest control alternatives beyond the organic-conventional divide. Many farmers use a pest prevention strategy called integrated pest management, which calls for using pesticides judiciously and only when necessary.
Not all pesticides are created equal, and the question of whether or not to use a pesticide can be a complicated one, as every chemical (both natural and synthetic) comes with its own benefits and drawbacks. Untreated pests can also cause plenty of damage, including wasted food, which means‘pesticide-free’ comes with plenty of risks too.

A new explore claims an organic food regimen can enormously gash again pesticide levels, but the learn doesn’t protect up.Published February 12 in the journalEnvironmental Be taught, the authors of the explore examined pesticide levels in the urine of 16 explore contributors, earlier than and after switching to an organic food regimen, and learned pesticide levels lowered after the change. However there’s more to the story.
The explore basically examined for the forms of pesticides allowed in veteran agriculture, and now not the pesticides allowed on organic farms. So what the explore truly shows in all equity evident: of us received’t flush out what they aren’t drinking.
The explore furthermore doesn’t tell one thing else about whether there’s anicely being threat associated with veteran pesticide residues, for the rationale that mere presence of a chemical in urine isn’t necessarily an unhealthy or unhealthy signal.
This explore can also very nicely be problematic, but it isn’t the first of its form. In 2015, a Swedish organic grocery co-op sponsored a the same explore with even less contributors, a family of 5 who had switched from a food regimen of conventionally grown meals to an all-organic one.
The outcomes had been the identical: when the contributors switched to drinking organic, the levels of synthetic pesticides of their urine lowered. However, another time, that’s attributable to of us who steer obvious of conventionally grown meals furthermore eat decrease levels of synthetic pesticides.
Very like this most most modern explore, the Swedish experiment didn’t test for organic-well-liked pesticides, which blueprint it didn’t camouflage that an organic food regimen truly lowered general pesticide levels, ideal that an organic food regimen is associated with decrease levels of one class of pesticide: synthetic.

It’s no secret that every organic and veteran farmers expend pesticides but, for basically the most fragment, organic growers expend pure pesticides in prefer to synthetic chemicals. Below federal law, pure pesticides are allowed in the USDA organic program, whereas most synthetic pesticides are now not well-liked. While many organic growers strive to expend fewer pesticides general, per the guiding options of organic agriculture, it would be wrong to pronounce organic meals as pesticide-free.
Whether organic or veteran, the final analysis is that trace levels of pesticides on meals don’t truly pose much of a nicely being threat to eaters. Farmworkers and develop packers, on the diversified hand, operate hang a better nicely being threat attributable to they’re exposed to pesticides more frequently and in better doses.
Farmers hang pest retain an eye on choices beyond the organic-veteran divide. Many farmers expend a pest prevention design called constructed-in pest management, which requires utilizing pesticides judiciously and ideal when foremost.
Not all pesticides are created equal, and the ask of whether or now to not expend a pesticide can also very nicely be a refined one, as every chemical (every pure and synthetic) comes with its hang advantages and downsides. Untreated pests can furthermore motive hundreds of damage, at the side of wasted meals, which blueprint‘pesticide-free’ comes with hundreds of risks too.
