  • Which supplements work — and which are a waste | Prof. Tim Spector & Prof. Sarah Berry

    Which supplements work — and which are a waste | Prof. Tim Spector & Prof. Sarah Berry
    Jun 5 2025
    Can pills and powders really improve our health? Despite their clinical look, most supplements aren’t tested with the scientific rigour we expect from medical treatments, and many don’t live up to their promises. Today, we're joined by two of ZOE’s top scientists to uncover the truth. They share groundbreaking new research and reveal the results of a brand new randomized controlled trial that could reshape how we think about supplements and introduce an entirely new kind. Tim Spector is one of the world’s top 100 most cited scientists, a professor of epidemiology, and ZOE’s scientific co-founder. He’s joined by Dr. Sarah Berry, a world leading expert in large scale human nutrition studies, Professor of Nutrition at King’s College London, and Chief Scientist at ZOE. By the end of this episode, you’ll have the latest science to help you make informed decisions about supplements and understand what your gut health really needs in 2025.

  • Recap: Do you need to eat meat to build muscle? | Simon Hill & Will Bulsiewicz

    Recap: Do you need to eat meat to build muscle? | Simon Hill & Will Bulsiewicz
    Jun 3 2025
    Today we’re diving into protein. It’s the nutrient at the centre of some of the biggest debates in nutrition - especially when it comes to building muscle. And as more people adopt plant-based diets, one question keeps coming up: Can non-meat proteins really support strength and overall health? So, what does the science say? Is it better to get our protein from animals or plants? I’m joined by nutrition expert Simon Hill and Dr. Will Bulsiewicz to break down the benefits of both, and to explore how we can build muscle in the healthiest, most sustainable way.

  • Harvard Doctor: Obesity, cancer, and the real cost of convenience food | Dr. Andy Chan

    Harvard Doctor: Obesity, cancer, and the real cost of convenience food | Dr. Andy Chan
    May 29 2025
    Ultra-processed foods now make up over half of what many of us eat - and the health consequences are only just coming into focus. In this episode, we reveal what’s really happening inside your body when you eat these foods daily. Our guest is Dr. Andy Chan, a Harvard professor and leading expert on gut health and cancer prevention. He heads the Clinical and Translational Epidemiology Unit at Massachusetts General Hospital and has published over 400 scientific papers. Dr. Chan breaks down the hidden links between UPFs, inflammation, and diseases like obesity, diabetes, and colorectal cancer. You’ll hear why some foods that look healthy on the shelf may be doing long-term damage - and how the gut microbiome plays a crucial role in the process. This is the research big food companies don’t want you to hear. If you care about what you and your family are eating, don’t miss this conversation.
