The increase in depression in industrialised societies has been linked to diet, particularly to reduced levels of omega-3 fatty acids in intensively farmed food and processed foods.[1]. This link has been at least partly validated by studies using dietary supplements in schools[2] and by a double-blind test in a prison. An excess of omega-6 fatty acids in the diet was shown to cause depression in rats[3].
