Triple Amen about the eating out. I imagine that most of us true Celiacs tolerate zero parts per million of gluten, never mind 20 ppm. The only time I got DH or other Celiac symptoms was the infrequent venture to a chain restaurant who cannot control their output as much as they claim. I think in general, although their intentions are good, people don't understand about cross contamination (and the waitress said, "I'll just remove the croutons." ).....the multi sourced spoon, spatula, pots, pans, toaster, and might as well mention the dreaded sponge. Been an 11 year diagnosis for me, with Type 1 Diabetes for 51 years. Intentionally eating, living well, and very grateful for today's medical community!!! Good luck with your journey!
