There is now good evidence that food allergy is an important aetiological factor in atopic dermatitis and that dietary antigen avoidance is a helpful form or therapy, particularly in younger children. Allergy history, prick tests and the RAST are of limited value in identifying the allergies present in individual children. A systematic practical approach to allergy diagnosis is currently under evaluation.
