What's Up Docs?

Chris and Xand take a closer look at cholesterol - what it is, why it worries so many people, and how diet and medicine fit into the picture. They’re joined again by Professor Nita Forouhi, Professor of Population Health and Nutrition at the University of Cambridge, to discuss why foods like seed oils become controversial, when cholesterol-lowering drugs such as statins make sense, and how her thinking on cholesterol has evolved over her career.Presenters: Drs Chris and Xand van Tulleken Guest: Professor Nita Forouhi Producer: Faye Lyons-White Executive Producer: Rami Tzabar Editor: Jo Rowntree Researcher: Grace Revill Tech Lead: Reuben Huxtable Social Media: Leon Gower Digital Lead: Richard Berry Composer: Phoebe McFarlane Sound Design: Olga ReedAt the BBC:Assistant Commissioner: Greg Smith Commissioning Editor: Rhian RobertsA Loftus Media production for BBC Radio 4.

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing.In this episode, they take on one of nutrition’s most misunderstood topics: fat. What is it, and why does our body need it? At what point does something normal and essential become something we worry about? What do cholesterol blood tests actually measure, and how well do they predict disease?Chris and Xand also explore the relationship between diet and cholesterol, asking how much influence what we eat really has, whether certain fats deserve their bad reputation, and what gets lost when we focus on single nutrients instead of overall dietary patterns.They’re joined by Nita Forouhi, Professor of Population Health and Nutrition at the University of Cambridge, to help separate evidence from hype and offer a clearer way to think about fat, cholesterol, and healthy eating.If you want to get in touch, you can email us at [email protected] or WhatsApp us on 08000 665 123.Presenters: Drs Chris and Xand van Tulleken Guest: Professor Nita Forouhi Producer: Faye Lyons-White Executive Producer: Rami Tzabar Editor: Jo Rowntree Researcher: Grace Revill Tech Lead: Reuben Huxtable Social Media: Leon Gower Digital Lead: Richard Berry Composer: Phoebe McFarlane Sound Design: Olga Reed At the BBC:Assistant Commissioner: Greg Smith Commissioning Editor: Rhian RobertsA Loftus Media production for BBC Radio 4

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken cut through the confusion around every aspect of our health and wellbeing.In this episode, Chris and Xand turn their attention to food.
