Kiwi allergy is caused mostly due to malfunctioning of the immune system. As a response to attack, antibodies are produced in a large number. These immunoglobulin E anti bodies engulf the foreign antigens. They will give signal to immune system to release histamines and other harmful chemicals. These are solely responsible for producing the allergic reactions throughout the body.
Kiwi allergy is also linked to the pollen food syndrome and latex allergy. Those who are allergic to tree pollen, they are most likely to get allergic symptoms to kiwi because of the resemblance in a protein building of both pollen as well as kiwi.
But, how it all starts?
Your immune system treats fruit proteins as harmful external substances. So it initiates response by releasing antibodies, which then leads to production of histamines. This reaction between harmless proteins and combating antibodies results in allergic symptoms which range from mild to severe situations.
As mentioned, people who’re allergic to pollen may develop kiwi fruit allergy because of similar protein structure. In the same way, you may expect allergic reaction with other ingredients that has identical substances.
