Cross-reactivity of tree nuts

Cross-reactivity of tree nuts

 

The following kinds of nuts are declared as «nuts» or «tree nuts» in Switzerland and Europe:

Almond, hazelnut, walnut, cashew, pistachio, pecan, macadamia, brazil nut.

Botanically, further nuts are among the tree nuts (like pine nuts), but these do not need to be listed as allergens in Switzerland and Europe, which makes it more people allergic to them to avoid to them.

Often, patients react to more than one kind of tree nuts, to be diagnosed in detail with your certified allergist if you suspect an allergy to nuts and/or peanuts.
