When you eat gluten, certain bacteria-made enzymes and gluten bits team up to sneak through your gut lining and get stuck underneath, where your immune system might mistake them for invaders and react.

Assessment Explanation
The claim describes a proposed biological mechanism involving co-transport and immune exposure, which is plausible based on known biology of gluten processing and gut permeability in celiac disease. However, the use of 'potentially' correctly reflects uncertainty. The claim does not assert inevitability, and existing in vitro and animal studies support the plausibility of transglutaminase-gliadin complex formation and transcytosis. A definitive causal link in humans remains unproven, so probabilistic language is appropriate.
More Accurate Statement
“Microbial transglutaminase and gliadin peptides may be co-transported across intestinal epithelial cells and deposited in the subepithelial space, where they could form novel antigen complexes that potentially activate the immune system.”

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
The study says that a food additive called mTG and a wheat protein (gliadin) stick together and get pulled through the gut lining into the tissue underneath, where the immune system can see them — exactly what the claim says.
