Episode 13: Food as Information, Not Just Fuel

Welcome to Live Longer Better, where patient advocate Leslie Kenny and Professor Sir Muir Gray explore the science, habits, and mindset shifts that help us thrive as we age. In this episode, we take a fresh look at food—not simply as calories, but as information that communicates with our cells and influences our long-term health. 🍎 Food, Ageing & the Exposome Professor Sir Muir Gray introduces the fascinating concept of the exposome—the sum of all the environmental influences that shape our health throughout life. From supermarket shelves packed with ultra-processed foods to the abundance of fast-food outlets near schools, our food choices are influenced by far more than willpower alone. ___________________________________________________ Key Topics Covered: • What the "exposome" is and why it matters for longevity • How our food environment shapes health outcomes • Why the Mediterranean diet remains one of the most effective dietary patterns for healthy ageing • The rise of ultra-processed foods and their impact on health • How diet affects weight, cardiovascular health, and disease risk • Fasting, time-restricted eating, and whether they really work • Why exercise may be just as important as diet for longevity • Understanding the mismatch between our evolutionary biology and modern lifestyles ___________________________________________________ Key Takeaways: ✅ Think of food as information, not just fuel ✅ Prioritise whole foods and minimise ultra-processed foods ✅ Focus on sustainable eating patterns rather than fad diets ✅ Remember that your environment strongly influences your choices ✅ Combine good nutrition with regular physical activity for the greatest health benefits From the Mediterranean diet to fasting trends, this conversation explores what the science currently tells us about eating for a longer, healthier life—and why the biggest challenge may be changing the environments that shape our daily decisions. Whether you're interested in longevity, nutrition, healthy ageing, or simply making better food choices, this episode offers practical insights to help you live longer and better. ___________________________________________________ 🌍 About the Oxford Longevity Project The Oxford Longevity Project (OLP) is a community interest company dedicated to translating the latest research in healthy ageing, longevity science, and healthspan optimisation into practical action. ___________________________________________________ 🌐 Follow Oxford Longevity Project YouTube: @OxLongevity Instagram: @oxfordlongevityproject LinkedIn:   / oxford-longevity-project   Website: oxfordlongevityproject.org Newsletter: https://tinyurl.com/olpnewsletter ___________________________________________________ 🤝 Sponsored by Oxford Healthspan Supporting evidence-based approaches to healthy ageing and longevity.
