Eggs and egg products are listed among the ingredients causing allergies or intolerance.
Egg intolerance is defined as egg-white-induced, small intestinal mucosa damage that is reversed by an egg-free-diet and reoccurs on challenge.
It is an abnormal physiologic response to ovalbumin in genetically predisposed individuals.
Although egg intolerance has often been associated with children, it can arise at any age.
The reaction includes metabolic, toxic and inflammatory response to ovalbumin.
Egg intolerance can produce eczema and a rash. Sufferers need to avoid all eggs and egg products.

Composition of egg
Most eggs sold to consumers are white-shelled eggs that have not been fertilized. The type of hen bred determines the color of shell.
A popular food, non-fertile chicken eggs are mass-produced, inexpensive, readily available and easily prepared.
Although they contain74 percent of water, they are such a rich source of high quality proteins.
Chemically, egg yolk contains proteins, lipids, cholesterol, pigments and a variety of minor organic and inorganic substances. The yellow color is due to the plant pigment xanthophylls – lutein.
The egg yolk is also rich in lecithin, a phospholipid used to emulsify other lipid.
In contrast, the albumin, or egg white, is described as almost pure aqueous protein, consisting of about 40 proteins.
Lipids, the main components of egg yolk, comprise about 69% of an egg yolk based on dry weight. In fresh egg, the lipids are combined noncovalently with protein, largely in particles of lipoprotein and to a very small extent with carbohydrate.
Egg are an important source of unsaturated fatty acids – mainly oleic, iron, phosphorus, trace minerals, fat soluble vitamin A, E and K and B vitamins.

Eggs in nutrition
Eggs contains four major nutritional components: protein, lipids, all necessary vitamins (except vitamin C), and minerals.
Eggs are sources of high quality proteins (each provide 6 grams of animal proteins) and are in fact the standard against which the protein quality of other foods.
The fat content of eggs 6 grams is entirely in the yolk, the amount being equal to the amount of protein in the whole eggs (3 grams in the yolk and 3 grams in the white).
Eggs are rich in unsaturated fatty acids.
Eggs are rich in cholesterol and recent studies indicate that cholesterol from eggs does not have a negative effect on serum cholesterol levels.
They provide important sources of iron, vitamins and phosphorus. The iron in the yolk is valuable in helping to meet the required intake of this key mineral. Eggs are low in calcium, which is discarded in the shell.
Fat soluble vitamins A, D, E are present in the yolk; water soluble vitamins B complex are present in the white, the yolk or both. As a nutritional source of vitamin D, eggs rank second only to fish liver oils.
