How does food tolerance occur?

➢ Clinical tolerance develops to most food allergens over time, except for peanuts, nuts, and seafood; allergy to peanut, tree nuts, fish, and shellfish are generally lifelong, although 20% of individuals may outgrow peanut allergy. ➢ Children with low levels of peanut-specific IgE should be re-examined to determine whether they have outgrown their allergy
