About this episode

Dr Joanna McMillan discusses the importance of dietary fibre and its implications for health.

When discussing dietary fibre, it's easy to stray into awkward conversations about 'the other end' of eating. Thankfully, we have communicators like Dr Joanna McMillan to normalise these conversations about our nutritional health. Her new book, The Fibre Factor, explores how fibre has faded from the modern diet, and how not eating enough can have implications beyond healthy digestion. Guest: Dr Joanna McMillan , nutrition scientist, dietitian and author of The Fibre Factor: A Science-backed Guide to a Healthier Gut, Stronger Heart and Sharper Brain Get in touch: We'd love to hear from you!
