Food Allergy: A review and update on epidemiology, pathogenesis, diagnosis, prevention and management

This review provides general information to serve as a primer for those embarking on understanding food allergy and also details advances and updates in epidemiology, pathogenesis, diagnosis and treatment that have occurred over the four years since our last comprehensive review. Although firm prevalence data are lacking, there is a strong impression that food allergy has increased, and rates as high as ∼10% have been documented. Genetic, epigenetic and environmental risk factors are being increasingly elucidated, opening the potential for improved prevention and treatment strategies targeted to those at risk.
