Tree nuts are a common food allergen, and an allergy to tree nuts is an immune system response to proteins found in certain nuts. Common tree nuts that frequently cause allergic reactions include almonds, walnuts, cashews, hazelnuts, pistachios, and Brazil nuts, among others.
Cross-contamination is a significant concern for individuals with tree nut allergies, as traces of tree nuts can be present in various food products, including baked goods, chocolates, cereals, and ethnic foods.
Peanuts are a prevalent and potentially severe food allergen. A peanut allergy is an immune system reaction to proteins found in peanuts. Unlike some other allergens, peanut allergies often last a lifetime once developed and are less likely to be outgrown with age.
