Food allergy (FA) is an important public health problem that affects adults and children
and may be increasing in prevalence. Despite the risk of severe allergic reactions and even
death, there is no current treatment for FA: the disease can only be managed by allergen
avoidance or treatment of symptoms. Moreover, the diagnosis of FA may be problematic,
given that nonallergic food reactions, such as food intolerance, are frequently confused with
FAs. Additional concerns relate to the differences in the diagnosis and management of FA in
different clinical practice settings.
