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.

Revisiting Wages for Housework, with Emily Callaci

Unpaid domestic labor has long been the invisible backbone of economies worldwide - but what if it were compensated?

Six Kings and the Making of the English State, with Caroline Burt and Richard Partington

Six Kings and the Making of the English State, with Caroline Burt and Richard Partington

Between 1199 and 1399, English politics was high drama. These two centuries witnessed savage political blood-letting - including civil war, deposition, the murder of kings and the ruthless execution of rebel lords - as well as international warfare, devastating national pandemic, economic crisis and the first major peasant uprising in English history. In today’s episode, historians Caroline Burt and Richard Partington discuss the six Plantagenet kings who ruled during these two centuries, and the significance of these monarchs to England's emergent statehood. Drawing on original accounts and new scholarship, they explore the resonances between government, international relations, and the abilities, egos and ambitions of political actors, then and now.  Burt and Partington are joined in conversation by medieval historian and author, Helen Carr.

LinkedIn Founder Reid Hoffman on What Could Go Right with Our AI Future (Part Two)

LinkedIn Founder Reid Hoffman on What Could Go Right with Our AI Future (Part Two)

Reid Hoffman is one of the world’s most influential and successful entrepreneurs. The co-founder of LinkedIn, Manas AI, Inflection AI and part of the original team at PayPal, he has built companies that have shaped the internet and AI revolutions of the twenty-first century. As part of Reid’s staunch commitment to Democracy, he was a supporter of Kamala Harris in the 2024 US election. In March 2025, Hoffman returned to the Intelligence Squared stage to discuss how AI is rapidly changing our world and how we can use it inclusively to improve our lives and create positive change. Drawing from the themes of his new book Superagency: What Could Possibly Go Right with Our AI Future, he acknowledged the challenges of disinformation and dislocation in the jobs market but argued that we need to be optimistic about the immense potential of AI to increase individual agency and create better outcomes for society as a whole. Hoffman argued that we must embrace AI’s most important opportunities: AI tutors that can personalise education for each student; machines that can rapidly discover cures for diseases like Alzheimer’s and cancer; and AI-crafted inventions that can prevent climate catastrophe. Hoffman set out a positive vision for an AI world where these possibilities, and many more, become a reality.  ------ 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.

Kavita Puri and Sathnam Sanghera on War, Empire and the Untold Story of the Bengal Famine (Part Two)

Kavita Puri and Sathnam Sanghera on War, Empire and the Untold Story of the Bengal Famine (Part Two)

The Bengal Famine is the forgotten story of the Second World War. Between 1943 and 1944, at least three million Indians, all of whom were British subjects, died from starvation or diseases linked to malnutrition. It is one of the darkest chapters in colonial history, yet the memory of those millions who perished is not broadly nurtured in Britain, India or Bangladesh. There is no memorial, museum, or archive dedicated to them anywhere in the world – not even a plaque. Who better to shed light on these untold stories than the award-winning journalist Kavita Puri? Described by The Radio Times as ‘our foremost chronicler of the lives of British South Asians,’ Puri has received critical acclaim for her radio series and writing on Indian history. In March 2025 she joined author Sathnam Sanghera live on stage to uncover this tragic chapter of British and Indian history. Drawing on the themes of her hit podcast Three Million, Puri told the dramatic and complex story of British colonialism, Indian nationalism, global war and the end of empire, while challenging national mythologies, the prevailing British narrative of World War II, and what we understand a hero to be. Puri also discussed the extensive archival research that went into the making of the podcast, and the new discoveries uncovered by forensically piecing together the stories of eyewitnesses and survivors. ---- 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.
