The expression "nut allergy" can be misleading and confusing, as we tend to use it to describe an allergy to fruits of unrelated plants such as peanuts and nuts that grow on trees.

While peanuts are not tree nuts, individuals with an allergy to peanuts have an allergic reaction similar to those with an allergy to tree nuts.
