A bacterial enzyme used in food processing might glue together the cells lining your gut, making it leakier — and for people with celiac disease, this could make their symptoms worse.

Assessment Explanation
The claim describes a plausible biological mechanism supported by in vitro and animal studies showing microbial transglutaminase can cross-link tight junction proteins. However, direct evidence in humans with celiac disease is limited and mostly indirect. The use of 'potentially' appropriately reflects uncertainty in human translation. A definitive verb like 'does' would be overstated without clinical trials.
More Accurate Statement
“Microbial transglutaminase may enhance intestinal permeability by cross-linking tight junction proteins such as claudins and occludins, potentially compromising the gut barrier in individuals with celiac disease.”

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 can make the gut leakier, especially in people with celiac disease, by messing with the proteins that seal the gut lining—just like the claim says.
