Food allergies are a significant public health concern affecting children and adults worldwide. The majority of allergic reactions are caused by 9 common food sources, including milk, soy, eggs, peanuts, fish, shellfish, wheat, tree nuts, and sesame. These immune-mediated responses, categorized as immunoglobulin E (IgE)-mediated or non-IgE–mediated, can range from mild to life-threatening and require timely recognition and appropriate management. Advancements in research and the ongoing development of clinical guidelines continue to refine evidence-based best practices for diagnosing, treating, and preventing food allergies.
