It is now well-known that fibre has many benefits beyond just ‘keeping you regular’ – but the average Australian consumes only 60 to 80 percent of the recommended daily fibre quota (1). To learn more about prebiotic fibre and its role in gut and overall health, we sat down with dietitian and CEO of NRAUS, Dr Flavia Fayet-Moore. In the podcast, Flavia dives into the findings from her team’s research on fibre, explains how prebiotics, like inulin, can change the microbiome and shares the impact of the ever-popular low-carb diet on gut health. She also shares some simple tips for getting Australians to eat more fibre every day.


Dr Flavia Fayet-Moore’s 20+ year career has been dedicated to nutrition research which makes a public health impact. As CEO of NRAUS, she oversees and supports teams of highly qualified researchers to undertake world-class research; and specialises in communicating findings to ensure they are translated to practice. Since completing her PhD from the University of Sydney, Dr Fayet-Moore has focused her research and advocacy work on nutritional epidemiology, micronutrients, and bioactives; using findings to promote a food-first approach to address public health’s biggest problems, including vitamin D deficiency, anaemia, and chronic disease. Flavia is passionate about improving the health of Australians, especially among children and adolescents, through research and its translation.


In this episode, we discuss:

  • Why Flavia is so passionate about nutrition research
  • The latest in gut health research and how inulin supports gut health
  • The foods Australians are getting their fibre from
  • The effect of prebiotic fibre on gut health
  • Which foods naturally contain and are commonly fortified with the prebiotic inulin
