Doctors' Notes: Feet
14/04/2026 | 32min
Drs Chris and Xand continue their conversation about feet with Professor Anthony Redmond, an expert in clinical biomechanics at the Leeds Institute of Rheumatic and Musculoskeletal Medicine. Together, they examine common foot problems, from bunions to verrucas, and explore why diseases affecting our blood vessels or nerves seem to often show up in the feet. They ask what this reveals about how we understand our feet and how we should care for them.

Doctors' Notes: Cholesterol
07/04/2026 | 31min
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.

How should we think about cholesterol?
07/04/2026 | 29min
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.
