As a diabetic, if I was gluten intolerant, I would be in a bit of a hole as most of the subsitutes for wheaten flour, such as potato flour and tapioca flour, put the blood sugar up. I am not allowed much bread anyway and certainly not white. I read an interesting letter from a lady on a GF blog, whose husband was reacting to bread in general: she discovered quite by accident that if she left her homemade bread to prove overnight, he had no bloating, gas or discomfort. It was an interesting observation, I thought. Maybe everything is just made in too much of a hurry these days.
