A food allergy is an adverse immune response to a food protein.[1][2] Food allergy is distinct from other adverse responses to food, such as food intolerance, pharmacologic reactions, and toxin-mediated reactions.
The food protein triggering the allergic response is termed a food allergen. It is estimated that up to 12 million Americans have food allergies,[3] and the prevalence is rising.[4] Six to eight percent of children under the age of three have food allergies and nearly four percent of adults have them.[5] Food allergies cause roughly 30,000 emergency room visits and 100 to 200 deaths per year in the United States.[6] The most common food allergies in adults are shellfish, peanuts, tree nuts, fish, and eggs,[5] and the most common food allergies in children are milk, eggs, peanuts, and tree nuts.[5]http://en.wikipedia.org/wiki/Food_allergy
