Food, health and sustainability

Abstract

This review makes a case for taking an integrated ‘food systems’ approach to explore the links between health and sustainability rather than treating them as separate topics. Unlike more linear ‘farm-to-fork’ conceptions, a systems approach emphasises the links between domains and sectors, helping avoid perverse effects where an intervention at one point in the system can have unanticipated consequences at other points. Adopting this approach, the review argues that food security and sustainability are as much a socio-cultural as a technical challenge requiring the combined forces of researchers from the natural and social sciences together with a range of stakeholders from government, business and civil society. Meeting the twin challenges of health and sustainability will require changes to intensive food production systems, dietary change and reductions in current levels of food waste. The review explores why dietary practices are so resistant to change seeking alternatives to the deficit thinking that pervades much advice on ‘healthy eating’. It explores the locus of responsibility for food system change, emphasising the asymmetrical power relations that shape contemporary dietary choices. The review includes an example of food system research, the H3 project (healthy soil, healthy food, healthy people), which seeks to transform UK food systems ‘from the ground up’, adopting the principles outlined in the body of the review.
