Tree nuts are generally cross-reactive.
If one is allergic to a variety of nut, he or she should try to avoid all of them.
The list of common tree nuts include:
- Brazil nuts,
- hazelnuts (filberts),
- macadamia nuts,
- pine nuts,
Peanuts are not included in this group, as they are not technically nuts (but, rather, legumes). Anyone with a nut allergy, however, should be cautious because they may be processed alongside actual nuts.
