If a person allergic to egg consumes it, the immune system of the body considers the proteins present in egg as harmful invaders. So it reacts by producing specific antibodies to fight those proteins present in egg. These antibodies cause the release of various chemicals, which in turn affects our body' s systems and create different allergic symptoms like headache and nausea.

The best option for the egg-allergic person is to avoid eggs and the products containing eggs. Eggs are present in variety of products like chocolates, baked food and mayonnaise. So, while giving your daughter a ready made food, be sure that it is not containing egg. Generally, egg allergy disappears in kids when they grow, mostly when they are 5 years old.
