Abstract

Nutrition plays a variety of physiological roles in the maintenance of mental health, with some potential pathological participations as well. Indeed, suboptimal and anormal nutrition may be implicated in the underlying pathology of mental health disorders and may interfere with treatment response and recovery. Nutrient deficiency is widespread throughout the world, affecting in particular, but not only, low- and middle-income countries and individuals disproportionately. Therefore, the socially and economically disadvantaged population is at a higher risk of major mental health disorders, including depression. Robust recent data relates the poor nutrition or nutritional deficiency (e.g., dietary antioxidants, trace elements) to major depressive disorders. On the contrary, nutrients (e.g., essential fatty acids and folic acid) may be used effectively to treat depression or to augment the existing treatments. The purpose of this chapter is to discuss the current evidence regarding the role of nutrition in depression.
