    Most replayed moment: Is Our Food System Making Us Sick? | Prof Brian Elbel & Prof Tim Spector
    May 12 2026
    Today, we’re zooming out to look at the bigger picture. On this podcast, we often talk about things that you can do to improve your diet. However, you're not the only one who has an impact on your health. The truth is, our food system - from government policy to supermarket placement - has a profound influence on what we eat, how we eat, and ultimately how healthy we all are. So, what steps can we take to improve not just our own health, but the health of society as a whole? Today, I’m joined by Professor Brian Elbel and Professor Tim Spector to explore the forces shaping our food system — and the changes that could benefit our collective well-being.

  • How 'boosting' your immune system increases inflammation and 4 ways to support balance instead | Dr Giulia Enders

    How 'boosting' your immune system increases inflammation and 4 ways to support balance instead | Dr Giulia Enders
    May 7 2026
    What if boosting your immune system is the wrong goal? Today, Dr Giulia Enders explains how boosting immunity may increase inflammation and why your symptoms are often part of your body’s defence. Your immune system is not failing when you feel sick. It is trying to protect you. So what should you focus on instead? That’s the idea at the very heart of Giulia’s new book, Organ Speak. Giulia is a gastroenterologist and author whose previous book, Gut, sold eight million copies and helped convince the world that gut health was worth taking seriously. She explains how the immune system really works and why symptoms like a runny nose, cough, or fever come from your body, not the infection itself. You’ll learn how sugar may push the immune system toward inflammation, how stress can weaken it, and why sleep is key for producing immune cells. This episode also explores how exercise helps regulate your immune response. The core idea is simple: health is not about making your immune system stronger. It is about keeping it balanced. By the end of this episode, you will have practical ways to support that balance and habits to help your immune system respond in the right way. If the sneezing, runny nose, fever - all of it - are actually the whole point, how much energy should you spend in suppressing them? 🌱 Try our science-backed and tasty wholefood supplement Daily30 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: Do You Have High-Functioning Depression? | Dr Judith Joseph & Professor Sarah Berry
    May 5 2026
    Today, we’re shining a light on a lesser-known form of depression. When we imagine depression, we often think of someone unable to get out of bed, someone who struggles to complete daily tasks. However, many people with depression are the exact opposite. They meet deadlines, achieve goals and appear successful. Yet, on the inside, they feel disconnected and distant from joy. This quieter, harder-to-spot condition is known as high-functioning depression. I’m joined by psychiatrist Dr. Judith Joseph and Professor Sarah Berry to unpack what high-functioning depression looks like, why it’s so frequently missed, and how we should approach it. Sarah starts by asking for clarity on a word that is closely connected to this condition. 🌱 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. 📚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 Eating for Better Brain Health: Your brain-gut blueprint 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

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!
