How are food systems, diets, and health connected?

This chapter considers the relationship between food and health, and in particular explores the the relationship between diet and health. We begin by considering the many ways (beyond the obvious) in which food and health are linked, then go on to examine malnutrition in its three main forms: undernutrition, micronutrient deficiencies and overconsumption. The causes and the geographical and socio-economic dispersion of these three forms of malnutrition are highlighted, followed by a discussion of their societal and economic costs.
