The role of food allergy in etiopathogenesis of skin diseases is a controversial problem. The incidence of food allergy in general paediatric population is 3‑8%. The most common sensitising allergens are cow’s milk proteins as well as eggs’ and nuts’ allergens. Higher incidence of food allergy has been detected in children with atopic diseases. It seems that food allergy may be the earliest sign and symptom of atopy in the atopic march. Many parents are convinced about the problem of food allergy in their children because skin lesions do exacerbate after ingestion of certain alimentary allergen. Often doctors themselves are responsible for the over‑diagnosing of food allergy and administration of restricted elimination diet without obtaining a detailed anamnesis and without performing appropriate diagnostic procedures. It is known that in the early childhood gastrointestinal and immunological systems as well as skin are not properly matured. Therefore, certain non‑immunological and/or non‑allergic reactions in relation to the food ingestion may develop. Different mechanisms of these reactions result obviously in distinct characteristics of skin lesions, different course of the disease and an appropriate spectrum of diagnostic as well as therapeutical procedures should be selected. In case of suspected food allergy, detailed diagnostics should be performed and what should be stressed results need to be evaluated in terms of their clinical importance. It seems that unjustified introduction of unnecessary elimination diets may be reduced in this particular way.
