Cross allergy

hazel nutsIf you are allergic to birch pollen, you may also react allergically to eating hazelnuts and apples. This may seem curious but it is one of a great many examples of what is known as cross allergy. An allergy is called a cross allergy if the antibodies that the body produces against one allergen start reacting to another allergen as well, for the simple reason that they are alike. They are related to each other, family, so to speak. Appearance does not enter into it: hazelnuts, apples and birch trees do not look like each other, but they contain related allergens, as do kiwi, pineapple and potato, for instance.
