What Is Egg Allergy?
Hen’s egg allergy is among the most common food allergies in infants and young children, but is less common in older children and adults. Most children eventually outgrow their allergy to egg (71% by 6 years of age),1 although some individuals remain allergic to egg throughout their lives.
When a person with an egg allergy is exposed to egg, proteins in the egg bind to specific IgE antibodies made by the person’s immune system. This triggers the person’s immune defenses, leading to reaction symptoms that can be mild or very severe.
Approximately 70% of children with egg allergy tolerate baked egg.2 Heating disrupts the protein responsible for egg allergy. The safe and regular ingestion of baked egg foods can lead to tolerance or resolution of egg allergy over time.3 Speak to your allergist before trialing baked egg products at home.
Experts estimate that as many as 2 percent of children are allergic to eggs.
