Although I don't want to do damage to my gut for fear of cancer and lupus and all of the other horrible things that can happen to a celiac who eats gluten, I'll tell you a "secret". As a smoker, I have to admit that all of those long term scares don't always work. I KNOW smoking can cause horrible things too, but I haven't quit yet.
But if smoking could cause DH...
Yes, DH is my greatest fear. I have read enough and seen the pictures of those who suffer from it, and I know I too could be one bite of gluten away from having it myself. There is NO WAY I would EVER risk that! So when the long term scare tactics don't work on someone who is playing Russian roulet with their health, I think they should all be required to go to the DH section here and read every post, look at every picture. I'd be willing to bet quite a few of them would wise up and stay STRICTLY gluten-free.
