  • 5 daily habits of people who live longer | Dan Buettner

    5 daily habits of people who live longer | Dan Buettner
    Jan 15 2026
    Would you like to stay healthy until you're 100? For most of us, the answer is, of course, yes. But why do some people live longer, and is it achievable? In this episode, best-selling author and longevity expert Dan Buettner, explores what decades of studying the people who live the longest reveal about health and lifespan. Instead of chasing hacks, the science suggests that a longer life is shaped by everyday food, social habits, and the places people live. We’ll look at practical habits seen across the world’s blue zones, rare global hotspots where celebrating your 100th birthday is common. Rather than relying on willpower, Dan explains why changing your routine and environment may be easier and more effective. By the end of the episode, you’ll have some simple tips to help you start your day like you live in a Blue Zone - and increase your chances of living healthily to 100.

    Recap: How your gut microbes could fight disease | Suzanne Devkota & Tim Spector
    Jan 13 2026
    Inside each of us lives a bustling community of microbes; tiny organisms that outnumber our human cells. They’re there from the very moment we’re born, shaping our immune system and influencing our long-term health. The science of the microbiome is evolving rapidly, but one thing is clear: We need to take care of these microbes so that they can take care of us. Today, I’m joined by Dr. Suzanne Devkota and Tim Spector to explore how our gut bacteria protect us from disease and what we can do to strengthen this vital partnership. 🌱 Try our new plant based wholefood supplement - Daily30+ *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system 📚Books by our ZOE Scientists The Food For Life Cookbook Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in Weeks Better Breakfast Guide Have feedback or a topic you'd like us to cover?

  • How to drink alcohol without destroying your health | Prof. David Nutt

    How to drink alcohol without destroying your health | Prof. David Nutt
    Jan 8 2026
    Dry January often raises big questions: how much alcohol is actually safe, and do you need to stop drinking altogether to protect your health? In this episode, world-leading alcohol expert Professor David Nutt explains why alcohol ranks as one of the most harmful drugs to society, how even “normal” drinking can affect your health, and what the science really says about cutting back without giving it up completely. David, a neuropsychopharmacologist and former UK government drug adviser, explains why alcohol was ranked the most harmful drug overall in a landmark comparison of 20 drugs, how harm rises sharply as drinking increases, and unpacks common beliefs like red wine being “good for you”. The conversation also covers the social benefits of alcohol and why the goal isn’t necessarily to stop drinking, but to drink with awareness. If you drink at all - whether it’s a glass most nights or more on weekends - this episode helps you understand where the real risks begin, and how to make alcohol work for you, not against you. And for listeners using dry January as a reset, David shares practical, science-based advice on how to cut down safely and sustainably. If you’re pausing and reflecting this dry January, what might change when you start drinking again? And which habits are worth leaving behind for good?

Once again, it is like Jonathan is reading my mind and asking all the questions I have! (except for the one on tomatoes...). Thank you for explaining the science and debunking the latest myth, which although one can see it's just aimed at selling a miracle cure in the form of one supplement, it's good to have the tiny doubts it raises squashed.

Great episode!

I've listened to this several times because I've found it so interesting. I was totally ignorant of this subject before hearing this podcast, and I'm not able to get the CGM test done, but the advice given is something anyone can take up, whether or not they know their blood glucose level. Thank you for this, and all the Zoe free podcasts.

Very helpful

Just listened to the programme about vitamins, and was amazed that the fact that BAME people deaths from covid were over represented and a link was made to lack of vitamin D. The advice given about vitamin D was clearly targeted at white people/those living in sunny climates. Those of us with melanin living in UK don't absorb enough vitamin D from sunshine. And if also a vegan then surely supplements should be taken? Also, there is an issue with absorption of vitamin D supplements. Even though I take supplements, my levels are still low. Why no research into why people of colour seem to not absorb vitamin D as a supplement?

Good information, annoying posh voices!
