Depression and food intolerance: a single case study.

Abstract

The detection and treatment of psychological dysfunction related to food intolerance with particular reference to the problem of objective evaluation is discussed. The case is described of a woman with chronic depression who exhibited classic signs of food intolerance and yet had remained untreated for over 10 years. A non-invasive procedure involving systematic monitoring of diet and symptoms, systematic eliminations and a double-blind, placebo-controlled re-introduction is described. Long-term follow-up revealed maintenance of marked improvements in psychological and physical functioning.
