Some processed wheat products treated with an enzyme called microbial transglutaminase might trick the immune system of people with celiac disease into thinking they’re under attack, causing inflammation and triggering harmful antibodies.

Assessment Explanation
The claim describes a biological mechanism involving immune recognition and activation, which is plausible based on known celiac pathophysiology and in vitro studies. However, the use of 'can stimulate' implies possibility rather than certainty, which is appropriate given that not all celiac patients may respond identically and human data are limited. The claim does not overstate causality but remains within the bounds of mechanistic plausibility supported by preliminary evidence. A definitive verb like 'does' would be overstated without population-level clinical validation.
More Accurate Statement
“Microbial transglutaminase-treated wheat products may be recognized by IgA antibodies from celiac disease patients and may stimulate interferon-gamma release and tTG autoantibody production.”

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)
This study says that a food additive called microbial transglutaminase, used to glue proteins in processed wheat, makes gluten more likely to trigger an immune reaction in people with celiac disease — exactly what the claim says.
