Food allergy is very common throughout the world and has become a major public health problem, with 220 million people suffering from it. Food allergy has been disproportionately observed in people from industrialized or Western countries and was previously considered to predominate in the pediatric versus adult population. However, the current exponential growth of the adult population and older adults, especially in Western countries, and environmental and lifestyle changes, have profoundly changed the epidemiology of food allergy, with a growing increase even at advanced ages. The foods that represent the greatest severity and clinical impact are peanuts, walnuts, fish, shellfish, eggs, cow's milk protein, wheat, soy and seeds. Although some types of food allergies (cow's milk and egg) may disappear, peanut and tree nut allergies may persist into adulthood. The control or cure of cow's milk protein allergy is gradual throughout childhood and adolescence. Despite the predominance of allergy to fish, shellfish, peanuts, and tree nuts in most reactions in adults, the most common form of IgE-mediated food allergy is oral allergy syndrome or pollen allergy syndrome. food.
