Pesticides Link to Parkinson's Disease
Pesticides, Parkinson's, and What We Can Actually Do
A heavy subject, handled with hope — and some simple, doable steps for your family.
This is a subject close to my heart, and I've circled around it for years. My own health journey taught me to pay close attention to what's in our food, and a while back a friend shared some research linking pesticides to Parkinson's disease that I simply couldn't stop thinking about.
Back then, the science was still pretty new. It isn't anymore. So I want to lay out, as honestly as I can, what we actually know now — and, far more importantly, what we can do about it. Calmly. Without fear.

What the science actually says
Two chemicals come up again and again: an herbicide called paraquat and a pesticide called rotenone. A landmark 2011 study of American farm families found that people with Parkinson's were roughly two and a half times more likely to have used them. And in the fifteen years since, the concern has only deepened. Researchers believe these chemicals can damage the mitochondria — the tiny "engines" inside our cells — and the very dopamine-producing brain cells that Parkinson's attacks.
Now here's the part I really want you to hear, because I promised myself this post would not traffic in fear: the strongest risk comes from heavy, repeated exposure. We are mostly talking about farmworkers, pesticide applicators, and people who live right up against sprayed fields. You are not going to get Parkinson's from eating one conventionally grown apple. This is about years of exposure — not a single strawberry.
That said, the bigger picture has shifted dramatically. Paraquat is now banned in dozens of countries — the entire European Union, the UK, even China — and yet it remains one of the most widely used herbicides here in the United States. Thousands of farmworkers who developed Parkinson's have taken its makers to court, the manufacturer has announced it is ending production of paraquat, the EPA has reopened its review, and the Parkinson's Foundation has come out in favor of a ban. (Rotenone's uses in the U.S. were mostly halted back in 2007.)
The EPA has so far said the human evidence isn't yet conclusive, and its review is still ongoing. So at the regulatory level, this genuinely remains a matter of debate — even as dozens of countries, a great deal of research, and a mountain of litigation all seem to be pointing in the same direction.

What we can actually do about it
But here's the part I love: while the scientists and the lawyers sort out the big picture, there is quite a lot we can do in our own kitchens, starting today. And the goal isn't some dramatic "detox" — it's simply lowering what comes in, little by little.
First, the most important thing, and I mean this with my whole heart: keep eating your fruits and vegetables — all of them. Every expert who studies this, the pediatricians included, says the very same thing: the benefits of eating lots of produce far, far outweigh the small risk from pesticide residue. Please don't let fear chase your family away from the very foods that keep you well.
From there, a few simple, doable steps: Spend your organic dollars where they matter most. Each year the Environmental Working Group publishes a "Dirty Dozen" list of the produce carrying the highest residues — things like strawberries, spinach, leafy greens, grapes, and peaches. Those are the ones worth buying organic when you're able.

- Relax on the "Clean Fifteen." Their companion list of the lowest-residue produce — avocados, sweet corn (non-GMO) pineapple, onions, and more — is perfectly fine to buy conventional. Nearly 60% of those samples test with no detectable residue at all, so go ahead and save your money there.
- Wash everything well. A good rinse under running water lowers surface residues (and germs, too). It won't remove what's absorbed deep inside the plant, but it genuinely helps.
- Consider a water filter. Because these chemicals can linger in soil and water, a good home water filter is a reasonable investment if you have concerns about your source.
- Grow a little of your own. Even a few pots of greens or tomatoes you can trust completely is a lovely, empowering thing.
- Buy frozen organic when fresh is pricey. It's often about the same price as fresh conventional — a wonderful little workaround.
And here is an encouraging part: studies show that when people shift toward more organic food, the level of pesticides measured in their bodies goes down — and climbs back up again when they return to conventional. Which means these small, ordinary choices you make in the produce aisle are actually doing something real.
I don't share any of this to frighten you — quite the opposite. I've spent a lot of years learning that fear is a terrible driver. We can't control every exposure in this modern world of ours; we simply can't. But we can make calm, informed, loving choices for the people at our table, do the good that's within our reach, and trust God with the rest. That isn't fear. That's stewardship. And there is a deep and steady peace in it.
With much love, Steffanie
