Tree nut allergy
Tree nut allergy is not one allergy but nine separate ones, and which nuts a child reacts to matters. Each guide below covers one nut: what it cross-reacts with, where it hides on a label, and what the evidence says. Start with your child’s nut, then check which others actually travel with it.
How these foods cross-react
If your child reacts to one, this is what else genuinely travels with it, and the shared-protein reason why.
