Yesterday's comments on my post about nausea and vomiting being a sign of glutening rather than gastrointestinal distress were interesting. I have been advocating for the past year that people should do a gluten challenge after being gluten free for a year. My experience in the trial mimics what they are describing and it was eye opening for me. It changed my understanding of how my body reacts to gluten exposure and I am now more aware of what happens to me.
