Tree Nut Allergy

Tree nut allergy is an immune system reaction to proteins found in nuts that grow on trees, such as almonds, walnuts, cashews, and hazelnuts. For individuals with this allergy, consuming even a small amount can trigger symptoms ranging from mild (like hives or stomach pain) to severe (such as difficulty breathing or anaphylaxis). This condition is distinct from peanut allergies, as peanuts are legumes. People with tree nut allergies must avoid all tree nuts and often need to be cautious with processed foods, as cross-contamination can occur. Consultation with an allergist is essential for management and treatment.
