I have been gluten-free by personal choice (not diagnosed) since February 4. On Saturday, March 10, I had pizza, thin crust, veggie. Within 48 hours, I had one episode of explosive diarrhea with these light reddish leaf or skin pieces that were very thin. I was able to wipe them out of my washing machine with paper towel, as they did not dissolve. There was a lot of it. Thank you, Dr.
