It goes with the territory. When you heal, you heal alone. It has taken a while for my family and friends to actually take it seriously but with an evergrowing market of gluten-free foods and mainstream pizza joints like Domino's going gluten-free along with famous celebrities and athletes, I think everyone will be well versed in what it all means. There was a time when people had a hard time pronouncing GLUTEN. I could see they refused to say the word or learn anything about it because it seemed foreign and distant. Besides, it hinted at giving up all those guilty foods we've been addicted to since we were kids and no one wants to hear any of that!
As time goes on and people figure out their problems, it will soon be common knowledge.
If not yet, then very soon everyone will atleast know someone affected by gluten.
