Step-by-step explanation:
Latex allergies are immune responses to latex, which is a natural substance made from the sap of the rubber tree. Some individuals with latex allergies may also experience increased reactions when they come into contact with certain foods. This is known as a latex-fruit syndrome. The proteins in certain foods, such as bananas, avocados, chestnuts, and kiwis, are similar to the proteins in latex, and can cross-react with the latex allergens, triggering an allergic reaction in some individuals.
