Tree Nut Allergy

Definition

Tree nut allergy is a common food allergy that occurs when the immune system mistakenly recognizes and attacks proteins found in certain nuts that grow on trees.

Scientific / Technical Definition

Tree nut allergy is an immunological hypersensitivity to proteins found in tree nuts, such as almonds, walnuts, hazelnuts, and pecans. When these proteins are ingested or even come into contact with the skin in sensitive individuals, they trigger the immune system to release chemicals like histamine, leading to allergic reactions. These reactions can range from mild hives or itching to severe anaphylactic shock, which can be life-threatening.
