Both my father and my sister are coeliac, and find a lot of packaged gluten free foods (biscuits, breads, cakes, etc) have more sugar than the normal versions to compensate for frankly generally tasting worse...
Fresh food is fine, but in general people deciding to go gluten free because it's trendy and "healthy", without having done a proper elimination trial or having coeliac disease, aren't actually making a good choice.
You forgot having active anti-bodies in their feces. I don’t have celiacs but I have done a fecal test and it showed sensitivity to gluten, oat, potato, and bean.
