Summary
What could reduce your risk of heart disease and stroke, lower inflammation, and make you less susceptible to depression? The answer, says nutritionist Emma Bardwell, is fibre.
Emma's back on the show by popular demand to explain why hitting 30 grams a day could transform everything from weight loss and mood to digestion and glowing skin – and the simple hacks that make it easy to hit that target.
In this episode:
- Why fibre needs better PR (and why protein hogged the limelight in 2025)
- The difference between soluble and insoluble fibre – and why you need both
- Fibre heroes: raspberries, cannellini beans, cacao powder and ground almonds
- How to go from 16g to 30g without eating mountains of vegetables
- The microdosing approach: starting with one teaspoon of beans to avoid bloating
- Why fermented foods and kefir are game-changers for your gut microbiome
- The Bristol Stool Chart and poophoria (yes, really)
- How fibre supports weight loss, hormone balance, and even clears microplastics
- Why your digestion slows in perimenopause – and what to do about it
- Emma's tips for cooking tempeh
- The timeline: what happens to your body within hours, days, and weeks of increasing fibre

| 0:51.8 | powerful shifts in what you eat, how you move, the way you sleep |
| 0:55.7 | and live can genuinely transform how you age. And the idea of extending lifespan is good, |

| 1:33.7 | It's kind of almost double, isn't it, for our bodies to really function optimally. |
| 1:38.2 | Well, registered nutritionist and health writer Emma Bardwell is back by popular demand. |
| 1:43.9 | You loved her evidence-based, |
| 1:45.8 | no-nonsense approach when she came on the show last year to talk about what healthy digestion |
