This is a groundbreaking book that looks at issues like mental illness from the perspective of psychonutrients.
From the book jacket:
"Dr. Philpott believes that one must search for and try to correct the underlying cause of allergy or allergic-like responses rather than remaining in an addictive state while swallowing symptom-suppressing 'medication.' The approach that the authors describe is one of sorting out real causes and applying corrective therapy."
