<<Disclaimer: Verify this information before applying it to your situation.>> I was diagnosed w/Celiac 8 years ago. I recently had a reaction, but couldn't figure out what was causing it since I had been on a strict gluten-free diet for the entire 8 years. Did some research on the net, and found out some gluten-free foods/drinks were *no longer* gluten-free. I had no idea that citric acid, mono and diglycerides, etc. were potential problems. If anyone has encountered this surprise reaction, let me know. Thought I knew, but still learning. Carol in New York
