  • The 5 best foods to fight cancer growth and lower your risk of death | Dr William Li

    The 5 best foods to fight cancer growth and lower your risk of death | Dr William Li
    Apr 23 2026
    You have around 10,000 cancer cells in your body right now, but most never become dangerous. The science suggests cancer risk is not just about genetics, but how your body responds to these cells. So what can you do, day to day, to support your body’s natural defences? In this episode, Dr William Li, a world-renowned physician, scientist, speaker, and two-time NYT Bestselling author, explains how everyday foods can fuel cancer growth or help your body keep it under control. We explore how cancer starts, why it is part of normal biology, and explain why lifestyle and environment are more important than genetics when managing your cancer risk. Dr Li shares simple guidance on eating patterns that support your body’s defences, including increasing plant-rich foods and reducing ultra-processed foods. He also highlights everyday habits such as staying active, supporting gut health, and limiting toxin exposure as ways to tip the balance in your favour. If your body is already managing cancer cells every day, what small changes could help it do that job better? 🌱 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.

One of the most powerful tools we have to control inflammation is right in front of us: food.

  • 5 simple nutrition changes to boost energy, lift your mood and beat fatigue (in just 72 hours!) | Prof Tim Spector & Dr Federica Amati

    5 simple nutrition changes to boost energy, lift your mood and beat fatigue (in just 72 hours!) | Prof Tim Spector & Dr Federica Amati
    Apr 16 2026
    Watch “The Gut Health Challenge” on YouTube | LINK Can you boost energy, improve focus and lift your mood in just a few days, just by changing what you eat? In this episode, Professor Tim Spector and ZOE’s Head Nutritionist, Dr Federica Amati, break down the simple nutrition changes that help beat fatigue and shift how you feel. They speak to Lucy and Sarah, who put ZOE to the test and changed only their nutrition for six weeks. At the start, they were held back by brain fog, poor sleep, and constant tiredness. Could a six-week nutritional reset really move the needle? This episode shows what happened in real life as they explore why many people feel tired or flat, even when tests look “normal”. The episode explains why your gut microbiome matters, how you can feel better within days, and why consistency beats perfection. You will also hear the simple changes they made. Bigger breakfasts. More plant diversity. Easy food swaps. Small habits that fit into real life. If you feel tired but your tests say you’re “fine”, what would you change first? And if you felt better in days, would you keep going for six weeks?
