Still Sick After Going Gluten-Free? You're Not Alone.
You did everything right. Threw out the bread. Read every label. Told every waiter. But you still feel awful.

Mistake #1: πͺ Sharing Kitchen Tools
The culprit nobody thinks about.
Your wooden cutting board? It has gluten embedded in the grain. Your colander, toaster, cast iron pan? All contaminated if they've touched gluten.
The fix:
---
Mistake #2: π Not Checking Medications

The Bottom Line
