Richard Westcott talks to Jonathan Stieglitz, IAST and Martin White, University of Cambridge, about  the global health challenges related to diet and nutrition, the roles of public health policies, cultural practices, and lifestyle changes, while creating sustainable food systems that ensure access to healthy food for all and maintain economic viability.

How do we address global health challenges, particularly in relation to diet and nutrition? What role do public health policies, cultural practices and lifestyle changes play in shaping our food choices? How can we create food systems that ensure everyone has access to healthy and sustainable food while maintaining economic viability?

To explore these issues, Richard Westcott talks to Prof Martin White, Professor of population health research from the University of Cambridge,  and Prof Jonathan Stieglitz, IAST Scientific Director.

Prof Jonathan Stieglitz is an anthropologist specializing in human health and aging.  He studies how evolved human biology interacts with variability in the environment to influence well-being over the life course. Since 2004 he has worked with indigenous Tsimane forager-farmers of the Bolivian Amazon, studying how environmental transition (for example, changes in infectious exposures, physical activity levels, or consumption of processed foods) influences diverse health indicators. He co-directs the Tsimane Health and Life History Project. 

Prof Martin White is an interdisciplinary scientist who leads research on food systems and public health, and has a particular interest in evaluation of population interventions to improve diet and health. He led the NIHR funded evaluation of the Soft Drinks Industry Levy and currently leads two UKRI interdisciplinary consortia on food system transformation (https://www.mandala-consortium.org/ and https://www.salientfoodtrials.uk). He was a visiting fellow at the Bennett Institute for Public Policy in 2020-22 and is a regular contributor to Cambridge University’s Centre for Science and Policy (CSaP) Policy Fellows programme for civil servants.
