I am fine with ciabatta bread. I prefer it toasted with some butter on, and maybe peanut butter or honey. That causes me no problems. I don't eat masses of it but usually at breakfast. It doesn't upset me at all.
But I have noticed that my gut is sensitive sometimes to eating pasta or cous-cous at dinner time. I am fine all evening if I eat that. I have it with only steamed vegetables, no sauces or tomato, and nothing but a sprinkle of salt in the cous-cous (boring though that is.). But I have a "looser" bowel movement in the morning if I have those. Sometimes not, but I'd say 60% of the time that's what happens.
I can't understand this mystery as I don't seem to be gluten intolerant when it comes to toasted ciabatta bread. Pastry seems OK for me too.
Unfortunately, potatoes (peeled and simply baked or boiled) have a similar laxative effect on me. The only carb to have with dinner that causes no upset at all is white basmati rice. But I do like to vary thing if possible. I don't want to have to eat rice or toast with dinner every single day!
Could this be gluten intolerance or what? Does anyone have any ideas?
