Peanut allergies are among the most common and severe food allergies, affecting as man as 2% of individuals in Europe and North America. In the past 20 years, rates of peanut allergy have increased 350%. Unlike tree nuts, peanuts are legumes, but they can still cause similarly severe reactions, including anaphylaxis. Symptoms usually manifest rapidly on exposure and can range from mild hives and itching to life-threatening airway constriction. While some children eventually outgrow a peanut allergy, more than 80% will carry it throughout their lives. As peanut allergies are the #1 most common cause of food reaction fatalities, strict avoidance of peanuts and products that may have been cross-contaminated is essential. It's also crucial to carefully read labels, as peanuts can be present in processed foods, snacks, and even in unexpected items like sauces and baked goods.
