I can tell you is absolute certainty that it is not glyphosate causing direct "gluten allergy" symptoms. In other words, once you have gluten allergy, cutting out glyphosate is not going to reduce your symptoms. This is something I studied heavily for well over a decade, including diving deep into the immune system, proteomics, gut and whole body biome (long before anybody in here ever heard the word "probiotics", which didn't really enter the main stream until around 2014). I know this sounds cocky, but there are few people as well read on this topic as I am. This all stems from somebody in my family having a serious auto immune problem, which let me down a rabbit hole of research for many years.

Glyphosate is toxic waste and can contribute to the death of your gut biome, which can also lead to GI allergies, including gluten. However, the actual chemical itself does not cause symptoms akin to gluten allergy or any other allergy. Eating completely organic (not nu-"organic", which actually allows growing food directly in a liquid substrate containing glyphosate, or dousing actual food products in glyphosate after harvest) wheat, for example, can and will still lead to the same degree of gluten allergies. Also, despite the copious amounts of fake anecdotal evidence (mostly by people who think they are gluten intolerant, because they saw it on TV, but actually aren't), to suggest that ancient grains (like Einkorn) will cause less problems, the only way to prevent gluten allergy is to either burn the gluten (over 550°F), or produce enough enzymes to denature the proteins in your gut before they cross the endothelium into your bloodstream (unlikely). One can supplement protease and other enzymes to reduce the amount of protein uptake, but it's not a full solution for anyone with a serious allergy.

The primary cause of gluten allergy is taking a course of strong antibiotics, which enters your bloodstream through your endothelium in your small intestine and destroys bacteria throughout your body, which will never be regained in its original form.

There are people who experience gut symptoms from gluten who do not have what would be described as celiac disease when tested for antibodies. This is a similar kind of allergy and is also not first order causally linked to glyphosate or other chemical exposure.

To summarize, glyphosate could be the original cause of GI gluten allergy in a lot of people cut off but is not the direct cause of the symptoms on an ongoing basis - once you have it, you have it. Further, it is most likely not the cause of celiac disease (for most, the only kind of gluten allergy that really matters).

Don't get me wrong, I eat only organic food and I hate the shit out of the FDA for allowing this toxic waste into anything close to our food; but, it's important to keep it real when it comes to understanding the science behind these problems.
