#4: Principle 3 - Eat Fibre

24 Oct 2018

Today’s show features my good friend Gut health researcher Dr Megan Rossi from Kings College London who has a specialist interest in the gut.

We discuss what gut health refers to, the microbes lining our digestive system and what effects these have on general health.

In essence the perfect person to give us the lowdown on gut health and what we need to be doing.

We talk about:

  • What’s the deal with gut health, is it a real thing and should you be bothered
  • An introduction to the microbiome – the population of microbes that live in and around our bodies, largely concentrated in our large intestines
  • A whistle stop tour through the research that lead to the microbiome
  • What types of microbes are there?
  • The difference in microbe populations and associations with diseases
  • What are the the future applications of microbiome focused treatments in emergency, community care and autoimmune disease
  • Testing our microbiome
  • How fibre, rather than protein, is actually much more lacking in diets
  • How to spot fibre on the supermarket shelves and where to get sources
  • Key ways of enhancing your diet including additional fibre rich foods, approach to medication and lifestyle factors


We round up with actionable tips on how you can improve your own health by looking after your gut using food and lifestyle tips.
