Food allergy and atopic dermatitis often occur in the same patients. Food-induced eczema
may be perceived as a controversial topic because the immunologic mechanisms have yet
to be fully elucidated. Nevertheless, published clinical studies have clearly demonstrated
that foods can induce symptoms in a subset of patients with atopic dermatitis. Those at
greatest risk are young children in whom eczematous lesions are severe or recalcitrant to
therapy. Allergy testing can be helpful but must be applied judiciously. A medical history
obtained by a skilled and knowledgeable health care provider is of paramount importance
to interpret test results appropriately. Finally, the implementation of proper dietary avoidance
can improve symptoms and provide safety from potentially fatal anaphylaxis. However,
if inappropriate prescribed, elimination diets can have significant negative nutritional
and social consequences.
