A sustainable diet is the ultimate goal, but achieving it is far more complex than most people think. The current Australian evidence suggests there are two key areas for improving the sustainability of our food supply: better production practices and reducing food waste. In this podcast, we’re joined by Dr Brad Ridoutt and Dr Gilly Hendrie to explain the ever-evolving research on sustainable diets. Brad and Gilly translate the current research into practical portion guidance messages dietitians can use in practice to help their patients eat to their needs and reduce food waste.



Dr Brad Ridoutt is a Principal Research Scientist with Australia’s national science agency – The Commonwealth Scientific and Industrial Research Organisation (CSIRO). His expertise is in life cycle sustainability assessment in the agriculture and food sectors which is used to address strategic challenges in relation to climate change, water scarcity, sustainable food systems, and sustainable diets. Dr Ridoutt is engaged in a range of international processes relating to the standardization of sustainability assessment and environmental labeling. His research is creating the main evidence base concerning the environmental impacts of dietary habits in Australia.


Dr Gilly Hendrie is a Research Scientist within the CSIRO Human Health Program. Her research is focussed on understanding dietary intake patterns and developing novel ways to improve our food choices to address key challenges like obesity and environmental sustainability. Gilly has designed many technology based interventions to change, support, and monitor dietary behaviour change for health. For example, the CSIRO Healthy Diet Score Survey has been completed by over 230,000 Australians; and she currently leads the scientific evolution of the CSIRO Total Wellbeing Diet Online.


In this episode, we discuss:

  • The key environmental indicators that contribute to a sustainable food supply
  • New evidence on the environmental indicator score
  • If eating healthily automatically means eating more sustainably
  • How to help people make more informed choices about sustainable diets
  • Ways dietitians can support their clients to eat more sustainably
