I'm not seriously allergic to anything, but mango and avocado skin makes my lips mildly itchy for like, 5 minutes. Not too intense for me to not eat them, though.
I have a very big aversion to all melon; hate the stuff, like you with bananas. Can't stand the taste or smell. Also, apple pie. I know how un-American that is, but I had food poisoning from chicken and this was the last thing I ate, so the first thing to come up and I've really hated it ever since.
