Allergen,Individual-FoodEgg YolkAnda

Egg yolk allergy is usually more prominent in adults, although it can affect individuals of all ages. Individuals that are allergic to egg yolks can usually safely consume egg whites without difficulty. When it comes to eggs, egg whites' proteins are more likely to cause an allergic reaction than the yolk proteins.

Items containing eggs should be avoided if an individual has an allergy to egg yolk viz. processed meat, mayonnaise, marshmallows, salad dressing, baked goods, pasta, cakes, cream-based foods, custard, doughnuts, waffles, ice cream, pudding etc. Additionally, an individual that is not allergic to egg whites should not eat them because of the possibility of cross-contamination between the two sections of the egg.

Like every allergy, an egg yolk allergy causes a reaction in the immune system. When contact is made with the allergen, the body views it as toxic and becomes sensitized, producing IgE antibodies against these contaminants. These antibodies trigger the release of histamines, which will cause the symptoms of an allergic reaction.
