Food allergy is defined as type 1 hypersensitivity reaction of IgE antibodies against food proteins. As its frequency increases in the world, food allergy is becoming more common in our country. Infants, who have allergic rhinitis, bronchial asthma, atopic dermatitis and food allergy in their families, have a high risk of food allergy. Therefore defining a protocol will be helpful for correct diagnosis and treatment in high risk infants. The aim of this protocol prepared by "Academia of Pediatric Allergy and Asthma Society" is to asist the family physicians and pediatricians for the diagnosis and treatment of food allergy as a resource and guideline.
