Egg allergy is one of the most common food allergies in children, affecting approximately 1–2% of children in the UK. Most children outgrow it — around 70% by age 16 — but adult egg allergy exists and requires careful management. The challenge of egg avoidance is significant because eggs are used so widely in both home and commercial cooking, appearing not just as a recognisable ingredient but as a functional component in products where their presence is not obvious.
Understanding the Allergy
Egg allergy is typically mediated by IgE antibodies reacting to egg white proteins — primarily ovomucoid (Gal d 1), ovalbumin (Gal d 2), ovotransferrin (Gal d 3), and lysozyme (Gal d 4). Ovomucoid is the most clinically important because it is heat-stable, meaning it survives cooking and causes reactions even from cooked egg. Some people with egg allergy react only to raw egg and tolerate cooked egg — this tolerance difference is significant for dietary management and should be confirmed through allergy testing and supervised challenge rather than assumed.
Egg yolk contains different proteins (primarily alpha-livetin and YGP42) that can also cause allergy. Yolk allergy alone is rarer than white allergy but exists. Some individuals react to white but not yolk; others react to both. Individual allergy profiles vary considerably and influence which egg-containing foods need to be avoided.
Symptoms
Egg allergy reactions range from localised (skin hives, eczema flares) to gastrointestinal (nausea, vomiting, cramping) to respiratory (runny nose, asthma) to severe systemic anaphylaxis. The eczema connection is particularly strong in children — egg is one of the most common food triggers for atopic eczema in infants and young children, and identifying and eliminating egg often produces significant eczema improvement.
Where Eggs Hide
Beyond obvious egg-containing foods (scrambled eggs, mayonnaise, egg sandwiches, quiche), eggs appear in: many baked goods including cakes, biscuits, pastries, and breads (as a binder and emulsifier), pasta (egg pasta vs dried pasta — fresh pasta typically contains egg), coatings and batters (tempura, breadcrumbed products), some processed meats, certain soups and sauces (egg as a thickener), ice cream and frozen desserts, some salad dressings, and many restaurant dishes where egg is used as a cooking or preparation component.
Egg on labels may appear as: egg, egg white, egg yolk, albumen, globulin, lysozyme, mayonnaise, meringue, ovalbumin, ovomucoid, ovomucin, ovotransferrin, ovovitellin, silici albuminate.
Egg-Free Cooking and Baking
Eggs perform multiple functions in cooking — binding, leavening, emulsifying, and adding moisture — which is why replacing them requires different substitutes depending on the application. Flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water) bind well in dense baked goods. Aquafaba (chickpea liquid) whips and aerates similarly to egg white. Commercial egg replacers provide consistent results for baking. Applesauce and mashed banana add moisture and some binding. The appropriate substitute depends on the primary function of the egg in the specific recipe.
