Next to cow's milk, hen's eggs are the most common cause of food allergies in children. They occur most frequently in the first year of life and decrease with age.
In the case of hen's egg protein allergy there is often a confusion of concepts. Subsequently the white, clear part of the hen's egg is described as egg white and the yellow part as egg yolk.
The allergy trigger in the hen's egg is not the egg white itself, but different types of protein that are contained mainly in the egg white. To treat hen's egg protein allergy it is necessary to avoid eggs. Even the smallest amounts can trigger anaphylactic shock in people with a strong allergy to hen's egg protein.
