The incidence of food allergy in children is between 6 and 8%.
Allergens to which children are allergic depends on the frequency and amount of exposure and varies therefore regionally. Thus, fish allergy is common in Japan, milk allergy in Europe, and peanut allergy in the U.S. In the US, every three minutes, a food allergy reaction sends someone to the emergency room. Every six minutes, it's an anaphylactic reaction.
The prognosis for an outgrowth of the nut and peanut allergy is less favourable than for other food allergies.
Only 20 percent of children with a peanut allergy and less than 10 percent of children with a nut allergy "outgrow" their allergy over the years. Most retain their allergies for life.
However, most children with food allergy to milk, egg, soy or wheat tend to overcome their allergy during their lifetime.
