The prevalence of food allergies is increasing worldwide, approaching an epidemic level in some regions. In the U.S. alone, approximately 10% of children and adults suffer from food allergies, with allergies to cow’s milk, eggs, peanuts, and tree nuts being the most common. Some patients have mild symptoms that might not need medical attention, leaving these cases unreported.
Food allergies, or food hypersensitivities, result from the overreaction of the immune system to typically harmless proteins in food. They can manifest as a spectrum of symptoms, ranging from itching, redness and swelling for milder reactions, to vomiting, diarrhea, difficulty breathing, and other potentially life-threatening symptoms for severe reactions.
