FOOD ALLERGY

[摘要] A VARIETY of disorders and symptom complexes have been ascribed to allergy—often to hypersensitivity to foods. In the majority of instances, however, it has not been possible to produce objective evidence for the existence of an antigen-antibody reaction and such a mechanism has been assumed rather than demonstrated. Instances of true food allergy occur. Their frequency however is difficult to determine with any degree of accuracy. Dr. Pratt (Pediatrics, 26:642, 1958) has properly called attention to the inadequate evidence on which practitioners as well as laymen frequently ascribe signs and symptoms to allergy to foods.Even when the diagnosis is based on good clinical observation, it may not be possible to demonstrate an immunologic mechanism.
