Atopic eczema is a common chronic inflammatory skin disorder, the cause of which is complex and not fully understood. Both genetic and environmental factors are likely to contribute, with defects in epithelial barrier function arising from abnormalities in structural proteins such as filaggrin making the skin both excessively permeable and more prone to damage from environmental irritants and allergens.
About 20% of infants under 2 years of age with moderate to severe eczema will have food allergy.
In infants under 2, food allergy can exacerbate existing eczema but there is no justification for manipulating diet or removing food until skin care has been fully optimised.
Dietary manipulation must be short term and under experienced supervision from an allergy team that includes a Dietitian.
Children over 2 years with eczema should not have dietary manipulation without expert medical assessment.
