Can someone react to bananas and pineapples who has never eaten a banana before?

Yes, you can. Bananas are present in a lot of flavoured milks, yoghurts, and fruit juices. It is also possible to have a cross-reaction: Bananas and pineapples have common allergenic structures with latex – so if you are allergic or sensitive to latex, a cross-reaction with bananas is possible. There may also be cross-reactions with avocados and melons. The indoor plant Benjamin’s fig is another possible source for this allergen which you shouldn´t have in your house if you are sensitive to it.

More information on possible cross reactions of foods tested in the ImuPro tests, please see this chart.
