Even if you don’t add more gluten to wheat bread, using a special enzyme called microbial transglutaminase can still make people with celiac disease have an immune reaction—like their body thinks it’s under attack.

Appropriate Language Strength

Assessment Explanation
The claim describes a specific biological mechanism—immune activation via IgA and IFN-γ—in a defined population (celiac patients) exposed to a specific treatment (microbial transglutaminase-treated wheat). This is a mechanistic claim that can be tested with controlled in vivo or ex vivo immune assays. Existing studies have shown that microbial transglutaminase modifies gluten peptides, enhancing their immunogenicity without changing total gluten content, which supports the plausibility of this claim. The use of 'elicit' is appropriate as it reflects a direct biological effect observed in controlled experiments.
More Accurate Statement
“Microbial transglutaminase-treated wheat products induce IgA reactivity and interferon-gamma release in individuals with celiac disease, even in the absence of changes to total gluten content.”

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)
Even if the gluten amount stays the same, adding a food enzyme called microbial transglutaminase makes wheat products more likely to trigger an immune reaction in people with celiac disease — and this study says that’s true.
