What in the World - Do I need to heal my gut?

Gut health seems to be everywhere on social media right now. Top tips for healing your gut, diet advice including things like sea moss and bone broth, and lots and lots of supplements.
But is there any truth to these suggestions, and should you care that much about your gut? Australian influencer Jade Chiang tells us why she works on her gut health. We get into what your gut microbiome actually is and whether you need to heal it with BBC science broadcaster Caroline Steel.

We also delve into trending food with microbiologist Alan Walker, who gives us some ideas on what actually works, and what you should skip.
