Drs Chris and Xand van Tulleken embrace this challenge; even as they marvel at the scientific breakthroughs, they grapple with the competing claims about health, wellbeing and how to live. </p><p>From understanding testosterone therapies to microplastics in our diets, and the concept of 'hangriness' to the power of saying no - this podcast deals with the health stresses we all face every day, while taking on board how the decisions by corporations and governments affect all our health. </p><p>Each episode, Chris and Xand are joined by an expert guest to examine the latest research, psychological insights, and data, to help listeners navigate the overwhelming amount of information and advice out there. They talk about the trials and tribulations in their own lives in their characteristically witty way - each teasing the other as they search for solutions. Xand has trouble sleeping , Chris has noisy knees, one of them has got an embarrassing itch. They have different ways of looking at things and find it really helpful to get the other one's point of view. These doctors are trying their best and encouraging listeners to do the same.</p>

    Doctors' Notes: Feet

    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

    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?

    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.

    Doctors' Notes: Buildings

    Chris and Xand continue their conversation about how the built environment affects our health, with architect Lisa Finlay from Heatherwick Studio.

    They ask when wellbeing first became a serious consideration in architecture, how Lisa weaves it into her own projects, and whether cities can be designed in ways that actively support public health.

    They also explore what the “healthy building” of the future might look like, and whether architecture could play a bigger role in preventing illness before it starts.

    Can buildings make us healthier?

    Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore the building blocks of our health and wellbeing.

    In this episode, they step outside into the built environment to ask: can buildings affect our health? From light and air to noise, materials and design, they explore how architecture shapes the way we feel, think and function.

    They visit Coal Drops Yard to see how a former industrial site was transformed into a modern public space, ask whether wellbeing is something architects actively design for, and explore what small changes we can all make to create healthier spaces. To help answer these questions, they’re joined by architect Lisa Finlay from Heatherwick Studio.
