Allergy to pineapple

It is still unclear why the immune system wrongly identifies certain proteins as a threat to the body, but if it malfunctions when pineapple or products that contain the fruit is eaten, the individual will experience an allergic reaction.

Pineapple juice is comprised of proteins that can initiate the overreaction of the immune system. The immune system will try to fight these proteins by generating immunoglobulin E antibodies into the bloodstream. Take note that these antibodies will trigger a chain reaction that leads to the production of chemicals which starts the manifestation of the allergy symptoms.
