The intersection of climate/environment, food, nutrition and health: crisis and opportunity

•Climate/environmental change (C-E-C) is adding to the complexity of global health.•C-E-C affects the planet's ability to sustain a healthy and diverse food supply.•Nutrition must be integrated as an input and output of the impact of C-E-C on health.•Responses to these challenges require multi-disciplinary collaboration.•Interventions are needed across the lifespan targeting low-resource settings.

Climate/environmental change (C-E-C) is affecting human health and quality of life. Significant attention has been given to the impact of C-E-C on food supply, and food as a vehicle for exposure. However, C-E-C has been superimposed on prevalent malnutrition, infectious and non-communicable diseases. We discuss why nutrition is not synonymous with food and must be viewed as a biological variable that affects and is affected by both C-E-C as well as the current global health challenges. The nexus of C-E-C, food, nutrition and health must be considered in the development of safe and efficacious interventions. A case is presented for how the convergence of C-E-C, food/nutrition and health, presents an opportunity for more integrated approaches to achieve global health goals.
