Relation Between Latex Allergy and Banana Allergy

Latex AllergyLatex is derived from the milky sap of the rubber tree known as Hevea brasiliensis. Latex is used in many products such as gloves, catheters, balloons, adhesives etc. Some people develop latex allergies as their immune system mistakenly identifies some proteins present in the latex as harmful and reacts against them. This results in allergic reactions such as sneezing, coughing, hives, itching etc.

Relation Between Latex Allergy and Banana Allergy:

Latex allergy is closely related to banana allergy. In fact, about 50% of people who have latex allergy may also have banana allergy. This is because certain allergy-triggering proteins present in latex are also present in banana. One such protein is chitinase, which is found both in latex and banana.

This phenomenon of being allergic to foods of the same group is known as cross-reactivity. In an allergic cross-reaction, a person responds with similar allergic symptoms when he/she is exposed to the foods belonging to  the same food group. Both latex allergy and banana allergy can result in hives, sneezing, coughing, itching, diarrhea and these symptoms may also lead to an anaphylactic reaction, which can be fatal

People who have latex allergy also have a risk of being allergic to fruits such as avocado, chestnut, passionfruit, plum, strawberry, tomato. This is known as latex-fruit syndrome.

To know if you have an allergy to latex or banana, you can consult an allergist who would conduct a skin prick test and/or blood tests for diagnosing allergies. Getting diagnosed is the best way to manage allergies.

  1. Thank you for your cogent thoughts on latex allergies; this is an important and often overlooked issue, and I found your words provocative and insightful.

    The organization I work for, the Pacific Northwest Foundation, is devoted to researching alternative modes of healing for a variety of illnesses, including latex allergy. I wanted to share with you a video presentation of a case study we conducted some years ago about a woman with severe latex allergy who, through a variety of methods, was able to diminish her reactivity. The link to the presentation is

    I’d like to thank you so much for your contribution to the subject of latex allergy, and hope you will find the case study above helpful in your continued exploration into the subject.
