enzymes?
Yes, maybe, sort of. The problem is that the intestinal flora, not just bacteria, but Archaea, viruses and other microorganisms, and even parasites, are very interactive with each other and the immune system.
If the gluten was digested by bacteria, it still might elicit an immune response. Some immune diseases like Crohn’s may actually be causes by an *absence* of a parasite.
So it’s likely going to be years before they start to get a handle on this.
