Laid by various bird species eggs are a common food item consisting of a protective eggshell, albumen (egg white), and vitellus (egg yolk). Chicken/hen eggs, duck and quail are the most commonly consumed eggs.

Whole eggs and egg yolks and contain large amounts of protein and choline and are used in various recipes. While eggs do contain a high nutritional value, a few health issues linked to eggs include egg intolerance and allergies to egg proteins, cholesterol and salmonella contamination.

Used in baking, mayonnaise, sauces, mousses, margarine, meringues, ice cream and as a binder to many processed foods they’re a versatile ingredient. Eggs can be easily separated into the white and yolk with sometimes only part of the egg being used.

An egg allergy is quite common in babies. Allergic reactions against egg whites are more common than against egg yolks. Allergic reactions are usually more severe than a digestive sensitivity.
