Diet-behavior relationships : focus on depression

Human beings persistently demonstrate a vivid interest in the effect of food on behaviour. Thoughout recorded history, every cultural and ethnic group has associated certain dietary practices and guidelines with particular physical and behavioural health outcomes. Some of these associations have survived as common sense or folk notions, many have disappeared and been discredited. Yet other notions have evolved and found some degree of scientific support, while others remain largely unexamined.
