As some may know I've been suffering for around 3 years yet and doctors still haven't figured out what's wrong with me, my doctor has said it sounds like I have IBS but he can't be certain as there is no way to test it. So he's told me to eat what I want when I want to see if there's any patterns that appear. And I just wanted to ask can you be intolerant to white bread but not brown? As I normally eat brown bread and I'm fine but this morning I ate a white bread roll and I've found myself stuck in the bathroom being sick,having Diarrhea and a large red rash appeared on my stomach, chest and arms. I also ate one of these bread rolls on Saturday and for the remainder of the day felt awful and found myself suffering with Diarrhea. It's clear to say I'll be staying well away from white bread or may just cut bread out of my diet altogether, I've made a note of this and took a picture of my rash to show my doctor at my next appointment.
