The results are in: six in ten Australians don’t eat enough fibre. That’s a real shame, because adequate fibre intake is essential for digestive health, and eating enough can reduce the risk of several chronic diseases. In this podcast, dietitian Joanna Baker discusses how prebiotic fibre differs from other fibres and probiotics, and its specific role in supporting gut health. Joanna also touches on which patients benefit from boosting their prebiotic intake and debunks some the most common myths in the gut health space.


Joanna Baker is a Dietitian & Registered Nurse who loves food. Her passion for digestive health stems from a lifelong battle with IBS which has taught her both how hard it is to live with an unpredictable gut and how life changing it can be when food sensitivities are well managed. Joanna is trained and experienced in the low FODMAP diet and food chemical sensitivities. She has presented to dietitians around Australia as well as in the USA on the low FODMAP diet and functional gastrointestinal disorders. She is currently on the Food Allergy and Intolerance Interest Group committee at Dietitians Australia and the advisory board for the Master of Dietetics at Deakin university. Most of all though, Joanna loves working with her team of dietitians at Everyday Nutrition where she supports people to manage their IBS and learn to enjoy food again.


In this episode, we discuss:

  • Joanna’s career journey in gut health
  • The diets that are typically low in prebiotic goodness
  • How prebiotic fibres can alleviate symptoms of constipation
  • The role of Partially Hydrolysed Guar Gum (PHGG), a type of prebiotic fibre
