Fruit Mix No.4 (kiwi, melon, banana, peach, pineapple) (fx21)

Fruit allergy can be caused by both true and "false" allergies. True allergy involves an immune system reaction to fruit proteins, leading to antibody production and histamine release with allergy symptoms. "False" allergy is caused by allergens deposited on the fruit from the environment.

Kiwi, melon, banana, peach, and pineapple contain various allergenic components that may cause cross-reactions with plant pollen, latex, and other fruits. For example, profilins, PR-10 proteins, lipid transfer proteins, and thaumatin-like proteins can cause oral allergy syndrome symptoms or more severe reactions, including anaphylaxis.

It is especially important to consider latex-fruit syndrome, which links latex allergy with reactions to bananas, kiwi, pineapple, and other fruits. People allergic to these fruits should be cautious with latex products.
