Abstract
The food system has become a nexus point for environmental and health problems, giving rise to the idea of modifying diet to produce health and environmental impacts. In this chapter, we review the literature examining the environmental and health impacts of food consumption and diet. First, we discuss the current state of the global food system and review the impacts of diet upon health outcomes. This leads on to discussion of the factors that are preventing healthy sustainable eating. We then summarize the literature about the environmental impacts of food consumption and diet, focusing on animal protein consumption. We review the two main methods of environmental impact assessment: life cycle assessment and environmentally extended inputoutput analysis; and evaluate the merits of the current metrics and functional units of environmental assessment. Finally, we highlight the main intervention types used to modify diet and reduce negative environmental externalities.
