Nutrition and behavior: complex interdisciplinary research.

Nutrition and behavior research presents a particularly challenging field of study for scientists. An overview is provided of research on nutrition and behavior of adequately nourished populations in industrialized countries. Discussions and findings from research presented include: refined carbohydrate consumption, maladaptive behavior, behavior disorders and learning; a history of the 'Feingold diet' and the basis for its controversy; an examination of recent critiques of research on artificial food dyes and hyperkinesis; indications for dietary intervention of hyperactive preschoolers; the role of iron in behavior disorders; effects of sub-clinical vitamin deficiencies on behavior; trace element analysis studies and violent behavior; and, suggested guidelines for further research into this complex and challenging field. Studies cited are from Canada, France, the United Kingdom, and the United States.
