A common form of allergy that affects millions of people globally is that of allergies to tree nuts. This is characterized by extreme sensitivity to products created in part with tree nuts that generates an extreme reaction in a person’s immune system. The resulting physical symptoms from this hypersensitivity can be mild or extreme and can hospitalize or cause death. Examples of tree nuts are walnuts, Brazil nuts, pistachios, chestnuts, pecans, cashews, macadamia nuts, pine nuts and hazelnuts. There are rare instances of allergies of one person to many if not all forms of nuts available and as a safety precaution they are advised to avoid any and all nuts available. For the majority though, this is not the issue even though some proteins in nuts to which one is allergic to is present in nuts to which they are not allergic to. Increased sensitization to any nuts will occur with prolonged exposure to the particular nut generating variations of allergic reactions from mild to extreme symptoms.
