Those long, unpronounceable ingredients at the bottom of food labels—what are they really doing to your health? In this episode, we’re joined by Professor Marion Nestle, a world-leading nutrition expert and author of the groundbreaking book ‘Food Politics’. Marion has spent decades exposing how powerful food companies influence what ends up on our plates — and how little regulation may stand in their way. We dive into the hidden world of food additives and the regulatory systems meant to protect us. While the U.S. allows companies to self-certify ingredients as “safe” without independent FDA approval, Europe and the UK take a stricter approach. But does stricter always mean safer? Marion unpacks how these systems differ, which substances might be harming our health, and what consumers can do to reduce their risk. We explore what the science says about additives, inflammation, gut health, and more.

Most people who try to lose weight and keep it off end up failing. But what if the problem isn’t you - it’s the diet? In this episode, we cut through the noise of weight loss fads to explore a science-backed method that’s helped countless people make real, sustainable changes. It’s called flexible dieting, and it’s built around the idea that personalised macronutrient targets, food quality, and consistency matter more than restrictive rules or trendy plans. Our guest is Alan Aragon, a leading expert in fitness nutrition who’s spent over 30 years coaching clients and publishing research that’s reshaped how the industry thinks about fat loss. Alongside Alan is Professor Sarah Berry, ZOE’s Chief Scientist, who brings insight from her studies on metabolism and how our bodies respond to food. Together, they unpack what actually works for long-term fat loss — and how you can get started with a realistic, effective approach that doesn’t require cutting out the foods you love.

Today, we’re diving into fermentation. If you’re a regular ZOE listener, you’ve probably heard that fermented foods are some of the best things you can eat for your gut health. Packed with beneficial microbes, they’ve been shown to boost everything from digestion to immune function. Still, the idea of at home fermentation - cultivating bacteria and microorganisms in your fridge - can feel a little daunting. More like a science experiment than a culinary adventure. That’s where Sandor Katz comes in. He’s a fermentation revivalist, bestselling author, and the driving force behind a global fermentation movement. So if you're a total beginner or just sauerkraut-curious, this episode will give you the tools, the confidence, and maybe even the craving to get fermenting at home. 🥑 Unwrap the truth about your food 👉 ⁠Get the ZOE app 🌱 Try our new plant based wholefood supplement - Daily30+ *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system 📚 Books from our ZOE Scientists:The Food For Life Cookbook by Prof. Tim Spector Food For Life by Prof. Tim Spector Every Body Should Know This by Dr Federica Amati Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition  Gut Guide - for a healthier microbiome in weeks Have feedback or a topic you'd like us to cover?

Scientists agree that processed foods are contributing to poor health — but when it comes to ultra-processed foods (UPFs), there’s growing confusion. The term is now used so broadly that it includes everything from crisps and sweets to wholemeal bread and plant-based milks. So what do we really know about the health effects of UPFs? And is the label actually making it harder for us to eat well? In this episode, Jonathan is joined by Dr. Sarah Berry, ZOE’s Chief Scientist. Sarah is a professor of nutrition at King’s College London who has run some of the world’s largest human nutrition studies. Her work explores how different foods — and how they’re processed — impact metabolism, fat storage, and long-term health. Sarah shares insights from her recent global conference talks, breaking down the good, the bad, and the misunderstood sides of ultra-processed food. By the end, you’ll have a clearer, more nuanced view of how to eat for your health — without falling for the hype.

He also outlines when we should eat protein, how much protein we really need, and provides simple, practical advice to help you achieve it. Stuart is a professor in the Kinesiology Department at McMaster University. He’s the author of more than 400 scientific papers, many focusing on protein and muscle health, particularly during ageing. With so much confusion around this topic - especially in the context of fitness and ageing - this episode will provide clear, evidence-based answers from one of the world’s leading scientists on the topic, to help you make smarter nutrition choices. 🥑 Make smarter food choices.

Today, we’re exploring the connection between your gut and your brain. For years, the brain was seen as somewhat detached from other parts of our body, working in isolation above all else. However, emerging research is flipping our idea of the brain on its head. Scientists now know that the gut acts like a ‘second brain’, influencing everything from our mood and memory to our risk of neurological disease. So, have we been neglecting a vital piece of the brain health puzzle?  Joining me to unpack this topic is Professor John Cryan, a world-leading expert in the gut-brain axis.

Omega-3 fatty acids have long been lauded for heart health benefits. Yet, emerging research now points to an even more profound impact, directly on our most complex organ: the brain. Today, we delve into the critical, often misunderstood, role of omega-3s in cognitive function, mental well-being, and even the prevention of neurodegenerative conditions like dementia. We are joined by Dr. Bill Harris, a globally recognised authority in omega-3 fatty acid research. Bill is a Professor at the University of South Dakota and has over 300 peer-reviewed publications. His foundational work includes pioneering studies on fish oil in the 1980s and shaping American Heart Association scientific statements. In this episode, Dr. Harris - along with ZOE's Chief Scientist Professor Sarah Berry - illuminate why most individuals may be operating with suboptimal omega-3 levels, and the tangible implications this has for mood regulation, anxiety, and long-term brain resilience. We navigate nuances between omega-3 types like EPA and DHA, debunk common misconceptions surrounding plant-based sources and mercury content in fish, and explore the precise methods for assessing and improving your own "Omega-3 Index."
