    Feb 19 2026
    Snacks make up a quarter of what most people eat. Yet most of us never question them. In this episode, Professor Sarah Berry, ZOE’s Chief Scientist, explains why snacking is not the problem and how seven snack swaps can lower cholesterol, support gut health, and reduce heart disease risk. Most snacks are high in sugar, salt, and saturated fat, and many carry “health” claims that hide this. Sarah breaks down how to spot this, explains what makes a good snack and why snack timing matters. You’ll walk away with seven simple snack ideas that help improve cholesterol, blood sugar, and heart health in weeks. If you’re a snacker, this may be the easiest place to improve your diet. 🌱 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.

    Feb 17 2026
    Today, we’re asking how we can boost our brain. Our brain is a living, morphing organ that is constantly responding to the stimuli we feed it. So the big question is: what sort of stimuli will keep our brain strong and healthy? Is it brain puzzles? Supplements? Neuroscientist Dr. Wendy Suzuki believes the most powerful way to support your brain is by simply moving your body.

    The #1 diet change to make today to fight chronic disease | Dr Mark Hyman
    Feb 12 2026
    Chronic diseases like heart disease, diabetes, and obesity are killing more people than ever before. Could your diet be the biggest driver of this risk? Today, Dr Mark Hyman explains why food matters more than genetics for long-term health, and how one diet change can make the biggest difference. Alongside Professor Tim Spector, Mark, a 15-times New York Times bestselling author and a practising family doctor, explores how modern eating is linked to chronic disease and what the science says reduces risk. We break down how food is designed to make us eat more, how this affects metabolism, insulin and inflammation, and why this matters more than your genes. By the end of the episode, you’ll understand the single most important dietary change Mark believes can lower chronic disease risk, based on clinical experience. If the modern world is driving these conditions, what’s one small change you can make to take back control of your future health? 🌱 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.

    5 ways relationships change your gut health | Prof Tim Spector
    Feb 5 2026
    Are modern habits around cleanliness, parenting, and social contact shaping your gut health more than you realise? In this episode, Professor Tim Spector explains how gut microbes are shared between people - through relationships, daily contact, and the environments we live in, and why this matters for long-term health. You’ll learn how human contact may be influencing your gut in ways most of us never consider. Tim explains why supporting gut microbiome is less about control and more about balance, and you’ll learn simple ways to support a healthier gut through food, social connection and lifestyle habits.

    Recap: The hidden clock controlling your health | Professor Russell Foster
    Feb 3 2026
    Today, we’re exploring circadian rhythms. Did you know you could eat the exact same meal at two different times of day and your body would respond drastically differently? It sounds like a riddle - but it actually comes down to your body clock. Every cell in your body has one. A tiny internal ticker, shaped by evolution over thousands of years, to keep you in sync with the phases of the day. So, how can we ensure we’re doing the right things at the right times?

    4 lifestyle changes that lower high blood pressure | Dr Sanjay Gupta
    Jan 29 2026
    High blood pressure is the number one risk factor for deaths globally. But what if your blood pressure numbers were only part of that story? In this episode, we’re joined by leading cardiologist Dr Sanjay Gupta, who explains why blood pressure is not a disease, but often a scream for help. Together with ZOE’s Chief Scientist, Professor Sarah Berry, he explores when blood pressure is a harmless response to stress, food, or movement, and when it signals real, long-term damage. You’ll learn why blood pressure targets aren’t universal, why worrying can make things worse, and why quality of life matters as much as numbers. This episode also breaks down what you can do to lower your blood pressure. Not quick fixes. Not pills. But everyday lifestyle changes that address the root cause. If your blood pressure is your body sending a message, what might it be asking you to change?

    Recap: Fat: The full story | Sarah Berry
    Jan 27 2026
    Today, we’re talking about fat. Since founding ZOE, I’ve actually started eating more fat. That might surprise you. Because for decades, we’ve been told to fear it. “Fatty foods will clog your arteries and send your cholesterol through the roof.” Right? Well, it’s not that simple. How ‘fat’ affects your health depends on a number of factors, including the type of fat, the food matrix and even how it’s produced. One thing is for sure, that single number on the front of a food packet, isn’t going to give you the full story. I’m joined by Professor Sarah Berry to dig deeper into fat.
