Non–Immunoglobulin E–Mediated Food Allergies

In food allergy, there is an unfortunate misconception that all allergies are equally dangerous. This third article on food allergies focuses on non–immunoglobulin E–mediated food allergy, which classically presents in infancy or early childhood and predominantly involves the gastrointestinal tract. Most non–immunoglobulin E–mediated food allergies have a good prognosis, with the majority outgrown in childhood, although a minority of cases do persist into adulthood.
