    Today we’re talking about mobility well as you age. As we get older, staying mobile becomes even more important. But often, it also becomes more difficult too. So today, we’re going to break down some barriers, take the slog out of staying active, and make movement fun. I’m joined by Gabby Reece and Dr Federica Amati to explore simple ways to stay agile as we age. From the surprising benefits of walking backwards, jumping in a swimming pool, and not wearing shoes. 📚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 How to eat in 2026 - Discover ZOE’s 8 nutrition principles for long-term health 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 tell if your poo is normal and the 5 warning signs you shouldn't ignore | Dr Trisha Pasricha

    How to tell if your poo is normal and the 5 warning signs you shouldn't ignore | Dr Trisha Pasricha
    Apr 2 2026
    Most people think you need to poo every day to be healthy. You don’t. In this episode, we explain how to tell if your poo is normal, the warning signs you shouldn’t ignore, and the gut mistake you may be making on the toilet every day. Dr Trisha Pasricha, a leading Harvard gastroenterologist, a columnist for the Washington Post and author of the book You’ve Been Pooping All Wrong, explains how your poo, gut health, and disease risk are linked, and when you should see a doctor. Dr Pasricha guides us through why frequency, colour, and consistency all matter, and why there is no single “normal.” You’ll learn how to spot changes that could signal disease, including early warning signs linked to cancer and long-term brain health. You’ll hear simple advice you can use straight away. This includes how to recognise your normal pattern, what changes to look out for, and how to avoid the common toilet habit that may affect your gut. Are you looking at your poo every day? And, if not, what might you notice if you did? 🌱 Try our science-backed and tasty wholefood supplement Daily 30 Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE Follow ZOE on Instagram.

    Most replayed moment: Lessons from a 5000-year-old diet | Frank Maixner & Tim Spector
    Mar 31 2026
    Today we’re going prehistoric. We have to stay sharp at ZOE. Nutritional science moves fast, so it’s important for us to stay up to date with new discoveries and the latest advice. However, every now and then, it helps to look back - way back. In this recap, we’re turning to a rather unusual teacher: a 5,000-year-old Iceman, preserved in ice and carrying clues about the diet of our ancient ancestors. I’m joined by Frank Maixner and Professor Tim Spector to uncover what this prehistoric man ate and what those findings can teach us about our diet today. 🌱 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 How to eat in 2026 - Discover ZOE’s 8 nutrition principles for long-term health 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?

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!
