All you Need to Know about Egg Allergies and Egg’s Substitutes

Egg allergy is a type of an allergy which develops when the immune system of the body overreacts and becomes sensitized to proteins present in egg yolks or whites. In such an allergy, when a person eats eggs, the body sees the protein as a foreign substance or invader and gives out signals to defend itself against eggs.

The chemicals sent out for defense cause symptoms of an allergic reaction. Some of the common symptoms of an egg allergy include stomach pain, respiratory problems, skin reactions like rashes and hives, and anaphylaxis.
