Favorite Apple?

Interesting. I only asked because I know people that are allergic to "pit fruits" which would include avocados (but not necessarily apples, I think).

That sucks about your allergies. I can relate, having developed an odd allergy to only crawfish in about the last 7 years or so. That sucks.

According to this, my fruit allergy stems from my tree pollen allergy (which makes sense if you think about it), but even still, it doesn't totally follow the list for me. I develop symptoms for carrots but usually not celery, for example. But then, yeah sometimes celery. But never avocados, and always peaches.

But that's Immunology. It is a strange, strange and highly individual-specific science.
