Peanuts are a good example. Some Airlines avoid passing them out as snacks for fear of severe allergic reactions.

Desensitization is strategy under study giving the patient minute exposure to the foods that make them sick.

Another possible breakthrough being studied is a Chinese herb nicknamed FAHF.
