Is it true that gluten can stay in your body for up to six months? I've been for lunch with some friends and as the restaurant couldn't find their gluten free menu (??) I thought to be on the safe side I'd just have some chips. Had just eaten a couple when a friend whose sister is Coeliac remarked that chips can sometimes be coated with wheat. They were suspiciously crunchy so I'm convinced they were. I'm not coeliac but have an autoimmune condition so I'm horrified. Is there any way of lessening the effects?
