No one ever answered the question, even to me personally, so I can't
provide you with any info.
In terms of the banana thing, I was diagnosed by a biochemist when I was
two and she also took me off bananas. Not because of gluten, but because
they are very hard to digest and babies really shouldn't be fed them in
her opinion. In general, I have a relatively sensitive GI track, so thing
that are hard to digest in general are more dificult for me, adn I find
that I definitely get gas from bananas. I would be interested in other
people's experience.
