Gluten isn’t a fodmap. Instead, fodmaps are present in almost all gluten containing foods. But sourdough bread has low fodmaps, but does have gluten.

So I think you’re conflating two issues. Celiac is an absolute intolerance of gluten, whereas fodmap ibs is based on being unable to digest large quantities. No one really knows why, and it’s not implausible some mechanism such as stress reduction or hypnotherapy would help.

Whereas for a celiac no such solution would work, there’s a real inability to digest. Perhaps in your case this extends to some fodmaps, but gluten isn’t a fodmap.

Also fodmap diets are generally elimination + reintroduction.

I am aware that gluten is not a FODMAP, I can not eat high fructose foods. Gluten causes my body to attack itself which has damaged my small intestine. That has caused fructose malabsorption.

Makes sense. I would note that people with celiac are much smaller than the group of people with IBS. For instance, I have a negative celiac test, no bowel inflammation, but do have IBS. And IBS in these cases is often linked to stress.

So while the app is inapplicable to your case, you’re overgeneralizing from your case to all cases.

(I would of course encourage anyone with IBS issues to get a gluten test. It’s important to rule out!)
