Glyphosate has never been more talked about than it is right now.
In April 2026, crowds gathered outside the U.S. Supreme Court for what they called the "People vs. Poison" rally, as justices heard oral arguments in Monsanto v. Durnell — a landmark case involving tens of thousands of cancer lawsuits filed by people who believe glyphosate exposure caused their non-Hodgkin lymphoma. A ruling is expected by the end of June 2026.
At the same time, the MAHA (Make America Healthy Again) movement has pushed glyphosate into mainstream conversation in a way that the holistic health community has been trying to do for years. Kelly Ryerson — aka Glyphosate Girl, who joined me on LIFELONG Podcast Episode 35 — is one of the most prominent voices in this national conversation right now.
The science is contested. The lawsuits number in the hundreds of thousands. And the chemical is almost certainly in your food right now. Here's everything you need to know — and what you can actually do about it.
What Is Glyphosate?
Glyphosate is the active ingredient in Roundup, the world's most widely used herbicide. It was originally discovered as a mineral chelator — a compound that binds to metals — and later found to have powerful weed-killing properties. Monsanto patented it as an herbicide and released Roundup in 1976.
Farmers quickly adopted it because it was considered less toxic than existing alternatives. Then in 1996, Monsanto introduced genetically modified "Roundup Ready" crops — corn, soy, and canola engineered to survive glyphosate spraying — which caused adoption to explode. Today, approximately 90% of corn and 85% of soy grown in the U.S. are Roundup Ready GMOs.
But the story doesn't stop at the field. Glyphosate is also widely used as a pre-harvest desiccant — sprayed on crops like wheat, oats, and barley about two weeks before harvest to dry them out and make harvesting easier. This means the herbicide is applied directly to the grain right before it becomes your food. And because glyphosate is applied so close to harvest, residue levels in finished food products can be higher than in crops where it was only used as a weed killer during the growing season.
This pre-harvest use is why over 80% of dietary glyphosate exposure comes not from produce, but from grains.

Why Is Glyphosate Controversial?
The scientific and regulatory debate around glyphosate is genuinely complex — and worth understanding.
The case for concern: In 2015, the World Health Organization's International Agency for Research on Cancer (IARC) classified glyphosate as "probably carcinogenic to humans." Multiple studies have linked glyphosate exposure to non-Hodgkin lymphoma specifically. Research also suggests glyphosate disrupts the gut microbiome by interfering with the shikimate pathway — a biochemical process used by beneficial gut bacteria — and has been associated with leaky gut, hormone disruption, and autoimmune conditions. A 2022 CDC study found detectable glyphosate in over 80% of urine samples from U.S. adults and children.
The regulatory position: The EPA has maintained that glyphosate is "not likely to be carcinogenic to humans" at current exposure levels, and has approved Roundup labels without cancer warnings. The EU reapproved glyphosate in 2023 for another 10 years, though several individual countries — including France, Germany, and the Netherlands — have introduced partial bans restricting its use in public spaces and home gardens.
What the lawsuits say: Bayer (which acquired Monsanto in 2018) has faced more than 100,000 lawsuits alleging glyphosate caused cancer. The company has paid out billions in settlements. The Supreme Court case currently in front of the justices — Monsanto v. Durnell — centers on whether Bayer can be legally shielded from state-level failure-to-warn claims because the EPA has not required a cancer warning on labels. A ruling is expected by the end of June 2026.
The bottom line: the science is not settled, the legal landscape is actively shifting, and the precautionary principle — especially for children — is well worth applying here.
Which Foods Have the Highest Glyphosate Levels?
This is the part most people don't know. The foods most contaminated with glyphosate are not the ones you'd expect.
Conventional oats are consistently the most heavily contaminated food in U.S. testing. The Environmental Working Group has found glyphosate in over 95% of conventional oat-based products tested — including children's cereals like Cheerios and granola bars. This is almost entirely due to pre-harvest spraying.
Conventional wheat is the second major concern. Whole wheat breads, pasta, crackers, and flour are regularly found to contain glyphosate residues. A 2026 study found glyphosate in popular bread brands including Nature's Own, Wonder Bread, and Sarah Lee at levels that raise concern for regular consumers.
Soy and corn are the primary targets of Roundup Ready GMO farming and consistently test positive for glyphosate residues.
Legumes — chickpeas, lentils, dried beans — are also regularly sprayed pre-harvest and frequently test positive.
Almonds, grapes, and certain other produce can also carry residues, though at generally lower levels than grains.
Important caveat on "Non-GMO" labeling: Testing has found that Non-GMO labeled products frequently contain glyphosate — because the label addresses genetic modification, not pesticide use. Non-GMO does not mean glyphosate-free. Only certified organic provides meaningful protection.
How to Reduce Your Glyphosate Exposure
You cannot eliminate glyphosate exposure entirely — it's too widespread in the food supply. But you can dramatically reduce your family's load with targeted, practical swaps.
1. Prioritize organic grains above everything else. Because the biggest source of dietary glyphosate is grains — not produce — switching to organic oats, organic bread, organic pasta, and organic crackers makes the single biggest dent in your exposure. This is where I focus first, especially for my son.
2. Buy organic for the highest-risk produce. The Environmental Working Group publishes an annual Dirty Dozen list of the most pesticide-contaminated fruits and vegetables. Prioritize organic for those. For lower-risk produce, conventional is generally fine.
3. Don't rely on "Non-GMO" labeling. As noted above, Non-GMO does not mean glyphosate-free. Look for certified organic or specifically Glyphosate Residue Free (GRF) certified products for the highest confidence.
4. Filter your water. Glyphosate has been detected in tap water supplies across the U.S. A high-quality water filter removes glyphosate along with hundreds of other contaminants. I recommend Clearly Filtered — it removes 365+ contaminants and is the pitcher I use in my own home.
5. Check your lawn and garden products. Roundup and other glyphosate-based herbicides are widely available for home use. If children or pets play in your yard, consider switching to a non-toxic alternative. Exposure through skin contact and inhalation is real.
6. Feed kids organic grains as a non-negotiable. Children's bodies are smaller, their organs are still developing, and they eat proportionally more grain-based foods — cereals, crackers, pasta — than adults. Studies have found glyphosate in over 95% of school lunch samples. For babies and toddlers especially, organic oats and grain-based foods are worth every penny.
What Is the MAHA Commission Report?
In May 2025, the MAHA Commission — a health advisory body focused on America's chronic disease epidemic — released a report that specifically highlighted concerns about glyphosate's role in the chronic illness crisis. The report acknowledged what many in the holistic health community have been saying for years: that the U.S. regulatory framework around pesticides has not kept pace with emerging science on long-term, low-level exposure.
Whether the regulatory and legal landscape shifts in the coming months, the underlying facts haven't changed: glyphosate is the most widely used herbicide in the U.S., it is in the majority of conventionally grown grains, and the long-term health effects — particularly on the gut microbiome and cancer risk — remain genuinely contested. As a consumer, you don't have to wait for a Supreme Court ruling to make smarter choices for your family.
Glyphosate and Your Gut
One of the most compelling mechanisms of harm — and the one I find most relevant for everyday health — is what glyphosate does to the gut microbiome.
Glyphosate works as a herbicide by disrupting the shikimate pathway — a metabolic process used by plants and microorganisms. While human cells don't use the shikimate pathway, the beneficial bacteria in your gut do. This means glyphosate can selectively damage the good bacteria in your microbiome while leaving more resistant, potentially harmful bacteria intact.
The result? Disrupted gut flora, increased intestinal permeability (leaky gut), compromised immune function, and — given the gut-brain axis — potential downstream effects on mood, cognition, and neurological health. This is why I consider reducing glyphosate exposure a core part of any gut healing or anti-inflammatory protocol.
The Bottom Line
Glyphosate is not going away overnight. The farming industry depends on it, the legal battles are ongoing, and the regulatory debate is far from settled. But the evidence that it has real effects on human health — particularly gut health and potentially cancer risk — is substantial enough that taking practical steps to reduce your family's exposure is absolutely worth it.
The good news: the swaps are manageable. Organic oats instead of conventional. Filtered water instead of tap. Organic bread instead of conventional whole wheat. These aren't extreme measures — they're smart ones.

FAQ
What exactly is glyphosate and where does it come from? Glyphosate is the active ingredient in Roundup and many other herbicides. It's used both as a weed killer on crops and as a pre-harvest drying agent on grains like wheat, oats, and barley. It was developed by Monsanto in the 1970s and is now the most widely used agricultural chemical in the world.
Which foods have the highest glyphosate levels? Conventional oats consistently test highest — glyphosate has been found in over 95% of conventional oat-based products including popular breakfast cereals. Conventional wheat (bread, pasta, crackers), soy, corn, and legumes like chickpeas and lentils are also high-risk. The key driver is pre-harvest spraying, not the growing process itself.
Does washing produce remove glyphosate? For produce, washing can remove some surface residues, but glyphosate is a systemic herbicide — meaning the plant absorbs it rather than just coating the surface. Washing is far less effective than it is for contact pesticides. For grains, washing doesn't help at all since it's incorporated into the grain itself during the pre-harvest spray.
Is glyphosate banned in other countries? Not outright in most places, but significantly more restricted. France, Germany, the Netherlands, Belgium, and Luxembourg have all introduced partial bans — prohibiting glyphosate in home gardens, public parks, and spaces near water. Vietnam has banned it completely. Several Gulf countries banned it in 2016. In the U.S., it remains widely approved and in heavy use.
Does "Non-GMO" mean glyphosate-free? No — this is one of the most important things to understand. Non-GMO labeling refers to genetic modification only, not pesticide use. Non-GMO crops are regularly sprayed with glyphosate. Only certified organic or specifically Glyphosate Residue Free (GRF) certified products provide protection.
What is the MAHA movement and why does it matter for glyphosate? MAHA — Make America Healthy Again — is a health advocacy movement focused on addressing the root causes of America's chronic disease epidemic, including pesticide exposure, food additives, and environmental toxins. In 2025, the MAHA Commission released a report specifically highlighting glyphosate's potential role in chronic illness. The movement has significantly elevated public awareness of this issue and is driving pressure for regulatory reform.
What's the most impactful thing I can do right now? Switch to organic oats and organic grain-based products — bread, pasta, crackers, cereals. This one change addresses the single largest source of dietary glyphosate exposure for most families. After that: filter your water and prioritize organic for the EWG Dirty Dozen produce list.
