Can Someone With a Nut Allergy React to Mangoes or Peppercorns?

Q: Testing has confirmed that our 4-year-old is allergic to cashews and pistachios. (We visited an allergist after our daughter’s reaction to one cashew, in which her eye and lips became swollen and she got hives.) I’m unclear about what other foods she’ll need to avoid. While those are the only nuts she tested allergic to, I’ve read that cashews are in the sumac family, along with mangoes and peppercorns. Will she need to avoid those too?
