Be prepared for the long haul.
There is no cure for allergies. Studies have shown that it is possible to outgrow food allergies, but it's not clear for whom this is true. The type of food also matters: People are most likely to get over milk, egg, and soy allergies. "You don't see many 30- to 40-year-olds who are allergic to those foods," says Stokes, adding that the likelihood of outgrowing shellfish, tree nut, and peanut allergies is much lower. Non-food-related allergies appear to be more resilient, though research suggests that the frequency and severity of allergic responses is lower for the elderly (overall, the immune system gets weaker as you age, and thus produces fewer IgE antibodies).
