Egg allergy is the second most common food allergy of all after cows' milk allergy but the most common allergy in children with atopic eczema.

Although studies have shown that about half of children with egg allergy grow out of it by 4 or 5 years of age, the other half will continue to be allergic to eggs at least until their adolescent or teenage years. Some may never outgrow their egg allergy, remaining allergic to eggs throughout adulthood.

Cerascreen is a simple, effective and comprehensive test for egg allergy (and 55 other foods) that you can do at home. Children, particularly infants, may find this less stressful than a visit to a hospital or the doctor.

Catering for someone with egg allergy is much simpler than before as you can now buy Egg Replacer, a clever blend of ingredients that you use instead of the eggs in recipes for cakes, quiches, pies, sauces and just about anything an egg-avoiding home cook could wish to make.

Another recent, and somewhat surprising, discovery as a replacement for egg is the water drained from a tin of chickpeas. Dubbed "aquafaba", bean water is cheap and effective and has taken the food allergy world by storm.
