Eggs Food Sensitivity and Egg Allergy
Although eggs are a very healthy and nutritious food, some people are allergic or sensitive to them.
If you are allergic to eggs, you probably already know it because you get a reaction such hives, skin reactions, digestive symptoms, airway symptoms, or facial swelling shortly after eating eggs.
However, there are others who are sensitive to eggs where there are no obvious symptoms. The person may not even feel any noticeable difference after eating eggs. However, a blood antibodies test would reveal they they have elevated antibodies against some of the egg proteins. That means that the immune system has been activated and is launching an inflammatory attack on the egg proteins.
The person may be reacting the ovomucoid, ovalbumin, ovotransferrin, and lysozyme proteins in the egg white. Or they may be reacting to the livetin, apovitillin, and vosvetin proteins in the egg yolk. Or both. These are known as antigens to the sensitive person.
It is rare to find a test that can distinguish between sensitivity to the egg white versus the egg yolk. So both the allergic person and the egg sensitive person needs to avoid the whole egg and all products made from eggs.
