Incidence

The walnuts that are available commercially are usually known as the Persian or English walnut. Furthermore, there is also another variety of walnuts. These are known as the Californian black walnut, or simply the black walnut. Of these two, the one which causes the majority of reported allergic reactions to walnuts is the English walnut. This can be attributed to its prevalence in the market. Another reason is that English walnuts contain twice as many allergenic proteins than black walnuts. Aside from walnuts, the person may also be allergic to other types of tree nuts. Almond, cashew, pistachio, or hazelnuts may also elicit an allergic reaction. Sometimes people who have allergic reactions to walnuts may also be allergic to peanuts.

This is explained by the medical community as a type of allergy cross-reaction. A cross-reaction between different tree nuts may be credited to its relative analogous protein components. Because of this, the immune system may mistakenly presume that it is the same allergen. Thus, its reaction will be the same as with the walnut allergen.

Diagnosis

An allergy to walnuts means that your body sees some proteins in walnuts as dangerous. As such, the walnut proteins are called as allergens.
