Of interest, ping.
Recent work regarding messenger RNA in Rice suggests another trigger for Sprue, whether "tropical" or simply a gluten intolerance.
Seems rice has little teeny tiny RNA fragments that can get in through your intestines and go to your brain and insert themselves in the nervous tissue ~ and tell you "EAT MORE RICE". This stuff also instructs the intestinal tract how to digest rice more efficiently.
The possibilities here are, of course, ENDLESS!
