Gluten has become a buzzword in the health space in the last several years, with most conventional doctors dismissing gluten as a problem unless a person has celiac. But, the truth is much more complicated.
The wheat we eat today is not the same grain our ancestors enjoyed. Our modern wheat has been bred to contain far more gluten (for various reasons), and since the 1990s our wheat crop has been saturated with glyphosate (Roundup). On top of that, it’s full of preservatives, fillers and other chemicals that don’t belong anywhere near food.
So the real question isn’t is gluten harmful? It’s what has happened to wheat, and how is it affecting our bodies?
A Short History of Wheat
History may not be everyone’s favorite subject, but when it comes to wheat, the backstory is important. The grain my grandmother baked with is not the same grain used in today’s sandwich bread. Understanding how wheat went from wild grass to an industrial crop might help explain why so many people struggle with it now.
From Ancient Grains to Wonder Bread
- 10,000 BCE – The Beginning: Einkorn and emmer (wheat varieties) are first domesticated in the Fertile Crescent (Middle East). These ancient grains are naturally lower in gluten and richer in protein, fiber, and micronutrients.
2,500–300 BCE – Ancient Civilizations: Egyptians, Greeks, and Romans ferment wheat into dense sourdoughs, making gluten easier to digest.
Middle Ages – Selective Breeding: Farmers start to breed wheat that’s easier to harvest and rises better, but those varieties also have higher gluten.
1880s – Industrial Milling: Traditional stone grinding is replaced with roller mills, which allowed for mass production of wheat but stripped away the bran and germ (where most of the nutrients live). This created shelf-stable but less nutrient-dense flour.
1950s – The Green Revolution: Semi-dwarf, high-yield wheat varieties are introduced. They contain more gluten, fewer nutrients, and dominate global production.
1990s – Glyphosate Enters the Picture: Farmers begin spraying wheat with glyphosate (Round-up) before harvest to dry crops quickly. Today, nearly all conventional wheat carries glyphosate residues thanks to this practice.
Over time we’ve created a grain that is more inflammatory and less nourishing than its ancestors.
In short:
Ancient wheat = diverse varieties, lower gluten, nutrient-dense, chemical-free
Modern wheat = semi-dwarf hybrids, higher gluten content + glyphosate residues + fewer nutrients + greater potential for gut and immune disruption
The Evidence Against Gluten
Let’s walk through what the research shows, and then consider what it means for our children and families.
Gluten Damages the Gut
Dr. Alessio Fasano’s research completely reshaped what we know about gluten’s impact on the body. In 2011, his team discovered zonulin, a protein that acts like a gatekeeper for the intestinal barrier. Normally, the cells lining the gut sit tightly together, connected by “tight junctions” that regulate what stays in the gut and what passes into the bloodstream. When this barrier works properly, it keeps food particles, toxins, and microbes out of the bloodstream.
But gluten changes that. Gliadin, one of gluten’s core proteins, stimulates zonulin release. Zonulin loosens the tight junctions, allowing fragments of food, bacterial toxins, and other unwanted particles to leak through the gut lining and enter circulation. The immune system immediately flags these as threats, setting off an inflammatory response.
This permeability shift happens in everyone, not just those with celiac disease. But in people with genetic susceptibility (like HLA-DQ2 or HLA-DQ8, which are linked to celiac and other autoimmune disorders), the effect is stronger and more damaging.
Repeated gluten exposure means repeated zonulin surges. Over time, the gut barrier weakens, creating a chronic “leaky gut” state.
Dr. Fasano’s research found that leaky gut isn’t just a side effect of chronic illness, it’s a prerequisite for autoimmune disease. In other words, if someone has an autoimmune condition they almost certainly have some level of intestinal permeability.
Dr. Fasano’s “three-legged stool” model for autoimmunity highlights how this plays out:
Genetic predisposition – an inherited tendency toward autoimmune disease.
Environmental trigger – gluten (or other triggers like infection or toxins).
Leaky gut – increased intestinal permeability, often mediated by zonulin.
When these three factors line up, the immune system can get confused, mistaking the body’s own tissues as threats. This explains why gluten is implicated in so many autoimmune conditions. It’s not because it always causes them directly, but because it can open the door for them to develop.
Glyphosate Adds Fuel to the Fire
If gluten is the match, glyphosate is the gasoline.
Damaging the Gut Microbiome
Glyphosate isn’t just a weed killer; it behaves like an antibiotic in the body, wiping out beneficial bacteria that we rely on for digestion, immunity, and cognitive balance. A 2023 study showed that even low-dose exposure—roughly matching the U.S. Acceptable Daily Intake—reduced levels of gut-friendly microbes like Bifidobacterium and Lactobacillus, and it raised markers of inflammation. Meanwhile, a genomic study found that over half of all human gut bacteria carry genes making them sensitive to glyphosate, including common, helpful species—suggesting disruptions in gut balance may occur across a wide range of people.
Interferes with Vital Microbial Pathways
Glyphosate blocks the shikimate pathway, a metabolic route that humans don’t have, but our gut bacteria do. This interference means those microbes cannot produce critical nutrients like folate, vitamin K, and aromatic amino acids. That leaves our bodies with fewer raw materials for brain function, detoxification, and immune regulation.
Contributes to Intestinal Permeability (Leaky Gut)
Just like gluten, glyphosate triggers zonulin release, increasing intestinal permeability (leaky gut). Dr. Seneff’s research demonstrates that glyphosate may act synergistically with gluten to loosen the gut barrier, helping explain the sharp rise in gluten intolerance since glyphosate became a harvest aid in the 1990s.
Systemic Dysfunction
Research suggests that glyphosate-induced dysbiosis could disrupt the gut–brain axis, contributing not just to gut dysfunction but also neurological and endocrine issues, from emotional dysregulation to cognitive decline.
Gluten, Glyphosate & Autoimmunity | A Perfect Storm
Gluten triggers the release of zonulin, loosening the tight junctions and allowing food particles, toxins, and microbes to slip into the bloodstream. This permeability provokes an immune response that doesn’t always shut off, and instead fuels systemic inflammation. Glyphosate compounds the problem by disturbing the gut microbiome and blocking key microbial pathways needed for nutrient production. It also makes detoxification harder, which means environmental toxins and metabolic waste build up in the body.
When gluten and glyphosate act together, the immune system can become confused and hyper-reactive. Instead of protecting the body, it begins attacking its own tissues, setting the stage for autoimmune reactions and other chronic illnesses.
A JAMA study that followed nearly 29,000 patients over several decades found that
People with celiac disease had an increase in mortality compared to the general population.
Those with intestinal inflammation but no full-blown celiac had the highest risk, with 10.8 extra deaths per 1,000 person-years.
In other words, gluten-related harm is not limited to full-blown celiac; sensitivity alone carries measurable risks. And, 30% of the population carries one of the HLA genes that makes gluten sensitivity more likely.
And, the damage doesn’t stop in the gut. Inflammation from gluten and glyphosate can ripple outward, affecting the nervous system and brain chemistry.
The Verdict?
Ancient grains were more nutritious and easier to digest. Today’s wheat is higher in gluten, laced with glyphosate, and stripped of nutrients. Centuries of selective breeding, industrial processing, and chemical farming have reshaped it into something very different from the einkorn and emmer of the Fertile Crescent. Today’s wheat contains more gluten, carries glyphosate residues, and offers fewer nutrients. For most people, this means a grain that is harder to digest and more likely to fuel inflammation.
The growing concern over glyphosate and gluten isn’t just about digestion, it’s about the broader immune response they trigger.
Dr. Alessio Fasano’s work shows that gluten opens the gut barrier in everyone, not just in people with celiac disease. For those with genetic risk factors, this shift sets the stage for autoimmunity. This is central to understanding the link between gluten and autoimmune disorders, especially in children already navigating chronic illness
Glyphosate compounds the problem by destroying the microbiome and blocking nutrient pathways. Together, they create a perfect storm for inflammation, autoimmunity, and neurological symptoms.
For children with PANS/PANDAS, autoimmune disorders, or autism spectrum conditions, removing gluten can be a game-changer. Many families notice improvements in mood, focus, and behavior once modern wheat is out of the diet.
In a world where 95% of wheat is the high-gluten, glyphosate-saturated variety, choosing to go gluten-free is about giving the body a chance to function the way it was designed to.
And, it’s one of the simplest ways to stop Monsanto/Bayer’s long-running experiment with our health.
Making the Transition | Going Gluten-Free for Kids
Helping kids transition to a gluten-free diet requires patience and creativity. Here are a few ways to make it smoother:
Find familiar swaps. Start by replacing the foods your kids already like with gluten-free versions. Gluten-free pasta has come a long way since the cardboard era. Things like spaghetti, macaroni, flour for baking, and crackers are easy swaps.
Go gradual. You don’t need to overhaul every meal at once. Start with breakfast or school lunches, then work your way up.
Introduce new foods carefully. For ARFID kids, new textures or smells can be overwhelming. Focus on slow, non-threatening exposure, and pair new foods with familiar favorites.
Watch for hidden gluten. Gluten has a way of sneaking into places it doesn’t belong — malt, soy sauce, modified food starch, even some supplements. Because of course it does. Learn to read the ingredient labels.
If you or your child struggle with gut issues, autoimmunity, or neurological symptoms, a gluten-free, glyphosate-free approach may be one of the most impactful changes you can make.
Reduce Gluten & Glyphosate | Lower Systemic Inflammation
The connection between glyphosate and gluten isn’t about trends. It’s about biology. When modern wheat opens the gut barrier and glyphosate disrupts the microbiome and detox pathways, the result is a system under constant stress. For children with underlying immune, neurological, or inflammatory conditions, that stress can tip the scale toward autoimmunity.
Your gut health is the foundation of overall wellness. Protect it, and the rest of your body will thank you.
