The challenges of preventing food allergy

Many challenges must be overcome to implement successful food allergy prevention strategies. Allergy testing of high-risk infants (those with moderate to severe eczema and/or egg allergy) before commencing oral tolerance induction is desirable, but access is not universal. Dietary interventions would ideally be implemented in infancy before allergic sensitization and allergy occur, using a program that provides protection against multiple common allergens. Further research and consensus with regard to food preparations, target populations, dosing regimens, and preparations and clearly defined adherence are now required.
