"Thanks for your reply! So white bread is highest in gluten? I guess the whole idea is to bombard your body with as much gluten as possible, so that would make sense. Why no sour dough bread though?  \n \nI'm sorry to hear you had a hard time with your GI, thats so frustrating to have to go through everything involved in a gluten challenge and endoscopy, only to find out that only one sample was taken! Thanks for the warning though, I'll definately speak to my GI about exactly what she intends to do. \n \nI am not looking forward to the next few weeks, but at least I will know I did everything I could to avoid false negatives! \n"
