People can be allergic to bananas. If you have ragweed allergies, you are probably allergic to bananas. Just handling them can bring on symptoms.
If you can’t eat avocados, kiwi fruit, tomatoes, bell pepper or potatoes without getting an itchy mouth or wheezing, you should eat bananas either.
Bananas contain proteins that are very similar to natural latex. If you are sensitive to latex, you could be sensitive to bananas as well.
