An allergy for any food type is commonly caused by an allergic reaction to certain proteins. Those people who suffer from an allergic reaction to a banana are not allergic to the banana itself, but rather the proteins found in a banana. The protein that can be attributed to banana allergy cases is referred to as chitinase, which causes the immune system of its victims to react negatively. This protein also occurs in avocados and kiwi fruit, which makes it possible for people allergic to bananas, to experience similar symptoms after consuming those types of food stuffs.
This allergy type is not a very common disorder. A majority of people who claim to be allergic to bananas will instead possess an intolerance for the fruit. The reason for the intolerance is often caused by a sensitize digestive system, which cannot digest certain banana amines.
