Does what we eat have an impact on our mood and memory? And should we be thinking about brain health when we make diet choices? Claudia Hammond speaks to Dr Ellen Smith from Northumbria University about the latest food supplement taking TikTok by storm; Lion's Mane mushrooms. We are used to foods being promoted for their physical health benefits, but this one is being claimed to reduce brain fog, improve memory and fend off Alzheimer's disease. Claudia asks what the science says and discusses with studio guest Dr Sarah King from the University of Sussex whether and what we should be eating to boost our cognition.

And Claudia's off to see a new play; This Might Not Be It is currently on at the Bush Theatre, London. It tells the story of two administrators in an NHS mental health clinic and addresses the challenge of staying optimistic in a system that is struggling. Claudia is accompanied by mental health campaigner James Downs, and speaks to the writer of the play, Sophia Chetin-Leuner. Studio guest Sarah King discusses why drama is so powerful in helping us connect with people's stories.
