The Bittersweet Truth About What We Eat

The Bittersweet Truth About What We Eat

What should we be eating to live a long and healthy life? How is it that some people can eat absolutely anything and stay slim, while others on a ‘healthy’ diet get fat? Why is it that Cubans are much healthier than Americans, despite eating on average twice the amount of sugar? To unpack the truth behind the often confusing information about the food we eat, Intelligence Squared brought together some of the world’s leading experts on the science of human nutrition and health. Sugar has recently replaced saturated fat as the nutritional enemy number one. The theory is that it messes with our metabolism and causes heart disease, obesity and diabetes. Arguing that sugar is the tobacco of the new millennium in our event was acclaimed science writer Gary Taubes, whose new book The Case Against Sugar has been making waves on both sides of the Atlantic. No one doubts that consuming a lot of sugar is unhealthy, but does the ‘sugar is poison’ theory really tell the whole story? A different explanation lies in a subject that has been getting a lot of attention recently – our gut microbiome. This is made up of the trillions of bacteria that inhabit our intestines and help digest our food and keep us healthy. The bad news is that the diversity of our microbes has plummeted in recent years due to the narrower range of foods and the predominance of processed junk in the Western diet. Research indicates that, rather than any single foodstuff being to blame for the rise of obesity and other modern diseases, the root of the problem lies in our depleted microbiomes. Setting out the new research on our gut bacteria and debunking many popular myths about diet was Tim Spector, an award-winning scientist who runs the British Gut project. What makes the subject even more fascinating is that we all have a very individual cocktail of bacteria in our gut, and research shows that the way we respond to food relates more to our own specific set of microbes than the calories in the food itself. Joining us was Eran Segal, one of world’s leading scientists in this field, who will explain how his lab can wire you up and predict precisely which carbohydrates you should and shouldn’t eat so as to prevent weight gain and be healthy. The results can be surprising. In 60% of cases, they show that you can enjoy sugary ice-cream but should avoid rice. A sharp critic of many of the ‘fashionable’ theories about diet and wellbeing is Sarah Jarvis, a GP who appears regularly on BBC radio and television. Her goal is to help her patients and the general public get the best quality information on nutrition and lifestyle so that they can make the informed decisions they need to be in control of their health. Chairing the event was Xand van Tulleken, a medical doctor and popular television broadcaster, who with his twin brother Chris, has presented a number of documentaries, often testing various diets on their identical genes.

How Tech Platforms Threaten Our Future, With Former White House Advisor Tim Wu (Part Two)

Tim Wu, is one of America’s leading thinkers on technology, power, and the history of monopoly powers. A Columbia Law School professor and former special assistant to President Joe Biden for technology and competition policy, Wu is best known for coining the term “net neutrality” and for his influential work in books like The Attention Merchants and The Curse of Bigness which explore the balance between innovation, corporate concentration, and the public good. On November 18, Wu came to Intelligence Squared to reveal the dangers of the new AI economy. Drawing from his new book The Age of Extraction he discussed why in the AI economy tech companies will amass unprecedented power and argued that breaking up tech monopolies is ultimately the only solution to unleash creativity and growth for the rest of society. He also discussed the history of monopoly power and offer a blueprint for an alternative AI future which would allow tech platforms to still play a major role in creating and sustaining an economic model of prosperity for everyone. --- If you'd like to become a Member and get access to all our full ad free conversations, plus all of our Members-only content, just visit intelligencesquared.com/membership to find out more.

How Philosophy Explains Our World, with Julian Baggini (Part One)

Michael Rosen on Hope, Happiness and Finding Joy in the Small Things (Part Two)

Michael Rosen on Hope, Happiness and Finding Joy in the Small Things (Part Two)

Michael Rosen has known – and given – great joy in his life. And he has suffered immense sorrow.  Rosen is an author, poet and former children’s laureate, much-loved for his playful humour. He has written over 200 books, including the modern children’s classic, We’re Going on a Bear Hunt. In recent years, he has become an eloquent voice on grief and sadness, and how we deal with it. His powerful writing about the death of his son and his near-lethal battle with Covid became Getting Through It, an acclaimed one-man show exploring love, loss and mortality. In 2023 he was awarded the PEN Pinter prize for what judges called a ‘fearless’ body of work that provides a ‘lesson in humanity.’ In September 2025, he came to the Intelligence Squared stage to introduce his new book, Good Days: An A-Z of Hope and Happiness. He celebrated the small things that bring joy and happiness, and explores how we can live well, even through difficult times.  Host Elle Osili Wood guided us through an inspiring conversation about grief, recovery, hope and how we can find meaning and happiness in everyday moments.  -- If you'd like to become a Member and get access to all our full ad free conversations, plus all of our Members-only content, just visit intelligencesquared.com/membership to find out more.
