Ways to Change the World with Krishnan Guru-Murthy

Prue Leith may be best known as a judge on The Great British Bake Off, but her influence reaches far beyond television. She founded a leading cookery school, built a Michelin-starred restaurant, spent decades shaping national policy on food education and public health, and has written extensively on ageing. This year she also served as a judge for The British Book Awards.

In this episode of Ways to Change the World, she speaks to Krishnan Guru-Murthy, reflecting on her latest new book ‘Being Old… and Learning to Love It!’ and talks frankly about growing older, staying relevant, finding happiness, and why she believes ageing can be liberating. Prue also discusses childhood nutrition, school food, her campaigns with Jamie Oliver, weight-loss injections, why she refuses to exercise, and the realities of caring for a parent with dementia.
This conversation includes discussion around suicide.

Amanda Knox became internationally known following the 2007 murder of Meredith Kercher in Pereugia, Italy, and the years of legal proceedings and media scrutiny that followed. Knox was found guilty of Meredith’s murder in 2009 but was ultimately acquitted in 2015.
She has since written and spoken extensively about her experience, and has advocated for others who may have been falsely imprisoned. Her latest documentary, Mouth of the Wolf, sees her return to Perugia, where she spent four years in prison - and confront Giuliano Mignini, the prosecutor who sent her to prison more than 15 years ago.
In this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Knox about accountability in the justice system, the importance of admitting when institutions get it wrong, and the lasting stigma that follows even after innocence is proven.

Heston Blumenthal is one of the world’s most innovative chefs, known for transforming the way we think about food, flavour and the dining experience. From his self-taught beginnings to building one of the most celebrated restaurants in the world, his career has been defined by curiosity, experimentation and a refusal to follow convention. But beyond the kitchen, Blumenthal has also been navigating deeply personal mental health challenges that almost led him to death at one point. 
In 2023, Heston was sectioned after his wife called medical professionals following a severe manic episode and bipolar diagnosis.

On this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Heston Blumenthal about his approach to mindful and sustainable eating, living with ADHD and bipolar disorder, and why he is determined to challenge stigma.

My guest this week is Eric Schlosser, the investigative journalist and author whose work has fundamentally changed how we think about what we eat. Fast Food Nation was a landmark book that exposed the abuse of animals and the exploitation of workers at the heart of America's food industry. 
Now, 25 years after it was first published, Schlosser says he is astonished that not only has the industry failed to improve, in many ways it has gotten worse. And yet, despite this, he still believes change is possible.

Warning: moderate strong language
Ece Temelkaran is an award-winning journalist and novelist who has spent years warning that the collapse of democracy rarely announces itself with a bang. Instead, it happens gradually - institution is weaken, truth is eroded and what once felt unthinkable becomes normal. 
Ece knows this first hand. After being fired from her newspaper in Turkey amid mounting political pressure, she watched her country slide towards what she says is authoritarianism, a story she believes is no longer uniquely Turkish but part of a wider global pattern. In her writing, she argues that the real danger isn't just strong men or populist leaders, but how easily societies adapt to them. Her latest book, Nation of Strangers, explores belonging and exile. But beneath it lies the same urgent question that has defined much of her work. How do democracies fail? And can they still be saved? 
On this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Ece about democratic backsliding, the moral crisis she believes sits at the heart of modern politics, the experience of exile, and why rebuilding democracy may require not just political change, but a deeper transformation in how we see ourselves and each other.
