Kriston-
I just want to mention that I have observed the weird mango/poison ivy connection myself. I couldn't understand why I kept getting poison ivy last year, in the fall after it was more difficult to contract. Turns out, a friend filled me in on the mango thing, as she'd been getting rashes too. I had been buying frozen mangoes and using them to make fruit smoothies. If I eat one mango in isolation, I am fine, but consuming the fruit several times a week was making me break out in rashes exactly like poison ivy!
I can't handle a lot fo dairy anymore myself. Going dairy-free fro years while nursing my first lactose sensitive babe seemed to affect my tolerance.
