A psychiatric study of patients with supposed food allergy.

Twenty-three patients who believed they suffered from food allergy were studied at the time of their presentation to an allergy clinic. The presence of organic food hypersensitivity could not be confirmed in 19 who attributed common neurotic symptoms to allergy; this group was almost identical, in terms of psychiatric symptomatology and general characteristics, with a group of new psychiatric out-patient referrals. There was no evidence of psychiatric disorder of food-related psychological symptoms in four patients with proven food-related atopic symptoms. The study failed to find evidence that psychological symptoms might be the result of organic reactions to foods.
