Are you allergic to latex by any chance? I ask because all the fruit and vegetables you are allergic are cross over food allergies with latex. I am also allergic to latex and I'm allergic to avacado, banana, tomato, pepper, potato and a bunch of orher fruits and vegetables. Kiwi/banana are two of the four that are highly related to latex allergies. It's not an underlying condition but it explains why you are allergic to what you are allergic to.
