How should we feed ourselves

Health promotion is tasked with creating environments that support health. To examine the gap between food advice given to individuals and how the systems supports people taking it, Fig. 2 explores the art and science of health promotion and uses the motivational interviewing principal of resolving ambivalence to order food-related knowledge into four quadrants. Longitudinal, prospective cohort studies inform the Science quadrant, while the Art, Lifestyle and Ethics quadrants draw on transdisciplinary literature on the history of nutritional science, a call for holistic frameworks for dietary assessment, a methodology that examine different ways of knowing, robustly evidenced normative food recommendations and popular diets and social movements with varied support in peer-reviewed literature but high cultural engagement. The Nexus question at the centre draws on a methodology used by IPBES  that identifies interlinkages that maximize synergies and minimise trade-offs. It invites the reader to think about their own experience of eating and asks, is sustainable and healthy eating possible at the nexus of the four quadrants. Read more on Fig 2 below.
