Some food allergies disappear as children grow. The allergies most often outgrown are milk and egg. Many children first tolerate these foods in baked forms, and studies show up to 90–95% eventually outgrow milk and egg allergies. Other foods, like peanuts, tree nuts, sesame and shellfish, are less likely to go away; fewer than 20% of children outgrow peanut allergy.
Several things influence whether a child will outgrow an allergy: IgE blood levels, how severe the reactions are, and family genes that affect skin and eczema. No genetic test can predict this reliably.
There is no home cure. Some clinics offer oral immunotherapy for peanut, using a measured product. Early introduction of peanut at four to six months and eczema care may lower risk.
