Tree nut allergy is a type of food allergy characterized by an abnormal immune response to proteins found in tree nuts, which are a specific category of edible nuts derived from trees. Tree nuts include almonds, walnuts, cashews, hazelnuts, pistachios, Brazil nuts, pecans, and macadamia nuts, among others. When someone with a tree nut allergy comes into contact with tree nuts, their immune system identifies the proteins from the nuts as harmful invaders and triggers an allergic reaction.
The symptoms of a tree nut allergy can vary in severity and may include hives, itching, swelling of the lips or face, difficulty breathing, wheezing, abdominal pain, nausea, vomiting, diarrhea, dizziness, and in severe cases, anaphylaxis, a potentially life-threatening allergic reaction. It is important for individuals with a tree nut allergy to avoid all forms of tree nuts, whether consumed directly or as ingredients in various foods, such as baked goods, sauces, and nut oils.
The D-definition of Tree nut allergy is a hypersensitivity or adverse reaction of the body's immune system when exposed to the proteins present in tree nuts. It is a specific form of food allergy, distinct from peanut or seed allergies. Tree nut allergies can range from mild to severe and may cause symptoms such as rash, itching, swelling, difficulty breathing, abdominal discomfort, vomiting, or anaphylaxis. Anaphylaxis is a potentially life-threatening medical emergency that requires immediate treatment with epinephrine.
People with tree nut allergies should avoid consuming tree nuts in any form, read food labels carefully to identify potential allergens, and inform others of their allergy to ensure the avoidance of cross-contamination. They may also need to carry an auto-injectable epinephrine device to administer
