Adverse food reactions may follow two main pathogenetic pathways: only reactions involving immunologic mechanisms belong to food allergy, whereas each reaction not proved to be immunologic must be defined as food intolerance. Many factors related to the gastrointestinal tract may interfere with the developing of symptoms, mainly by affecting transport and absorption of food components. Physiopathological and clinical aspects of food allergy and intolerance are described, with regard to symptoms, causative factors and diagnostic tools, including diet and provocation test. Once recognized, the food responsible for symptoms must be avoided; the resort to pharmacological therapy may be necessary to control symptoms or to prevent reactions to unavoidable foods.
