Why? I don’t know a thing about gluten. I think of flour actually. Why are you so gluten free? What do you mean?
My wife suffers from a condition called Celiac, which is an allergy to wheat gluten. In any form.
Whether it be in bread, flour or in a wide range of products including cheap soy sauce.
The gluten causes an acute GI reaction and can present as a host of other problems over the long run.
