About this episode

6 August 2026

Can your daily coffee actually be good for your brain, or should we be listening to the influencers who claim we need to cut it out?

In this episode of Change Your Mind, health journalists Helen Thomson and Cat de Lange dive into the science of caffeine to find out whether we can enjoy our coffee fix guilt free.

They’re joined by Dr Astrid Nehlig, a leading researcher on caffeine and the brain, to explore everything from the long-term effects of caffeine on our ageing brains, to the surprising ways coffee may be acting on our gut microbiome.

If you’ve ever wondered whether to cut down, quit or top up your cup, this episode might just change how you think about caffeine.
