ZOE Science & Nutrition

Today, we're diving into an important and growing health concern: colon cancer. Recent studies show that cases of colon cancer are becoming increasingly common in younger adults. In fact, the rate has doubled among people under 50 since the 1990s, prompting doctors to lower the recommended age for screening. So what can we do to protect ourselves and our loved ones? I'm joined by Harvard Medical School professor, Dr. Andy Chan, to talk about the importance of colon cancer screenings and how changes to our diet could help reduce the risk of this disease.

Finally, we'll share practical ZOE-approved tips for embracing spring with genuine, science-backed wellness strategies, helping you navigate the season of renewal with confidence.

Today we're exploring the impact that ultra-processed foods have on our brain. We often think of nutrition in terms of physical health - things like obesity, heart disease, or diabetes. However, what we eat also plays a crucial role in our mental health, influencing mood, cognition, and even our risk for conditions like depression. So, what can we learn from the studies that have looked into the connection between food and thought? I'm joined by world-leading Professor of Nutritional Psychiatry Felice Jacka to explore this fascinating link and discuss how we can make smarter food choices to keep our minds sharp and healthy.

Unwrap the truth about your food

Today we're exploring the power of a restricted eating window. Do you enjoy a late night snack? A little nibble or drink after dinner but before bed? If so, you're not alone - many of us indulge in this habit. After all, it's just a small treat, so it couldn't possibly have a big impact on our health… right? Well, a growing body of research suggests otherwise. That seemingly harmless snack could be disrupting your eating window and preventing your organs from functioning at their best. In this episode, Dr. Satchin Panda joined me to discuss the science behind time-restricted eating and how it interacts with our body's natural circadian rhythm.

We often associate depression with withdrawal and low energy - but what if it hides behind a packed schedule and staying busy? Board-certified psychiatrist Dr. Judith Joseph joins Professor Sarah Berry to explore high-functioning depression. Dr. Joseph explains how depression gets missed by medical professionals, explaining what's really happening in the brain. She shares how traditional definitions of depression often overlook people who appear to be coping, leading many to go undiagnosed and unsupported. We discuss how a busy, high-achieving lifestyle can actually mask the symptoms of depression - and even perpetuate it. Dr. Joseph, the first psychiatrist to run a lab focused on high-functioning depression, shares her latest findings on its causes, signs, and long-term impact. ZOE's Chief Scientist Prof. Sarah Berry explains how food and the gut microbiome may hold the key to reducing these symptoms. If this sounds familiar, Dr. Joseph introduces a quick self-test to help identify high-functioning depression - and outlines five practical strategies to begin healing, and Sarah gives you the foods that could help.

IBS affects over 300 million people globally, yet remains one of the most misunderstood gut conditions. In this episode, we explore the latest science uncovering the real drivers behind IBS - and why your gut microbiome may hold the key to understanding it. Joining us is Dr. Will Bulsiewicz, a board-certified gastroenterologist and ZOE's U.S. Medical Director. Dr. Will breaks down why IBS is so difficult to diagnose, how stress and modern lifestyles are making symptoms more common, and what “problematic” poo can tell us. We then dive into the science: how the gut-brain axis influences everything from pain to food intolerances, why women are disproportionately affected, and how a disrupted microbiome plays a central role in IBS. Finally, Dr. Will shares practical strategies backed by the latest research -  from dietary changes to cutting-edge treatments - offering hope for healing and prevention. Whether you're living with IBS or simply want to understand your gut better, this episode is packed with insights into one of the most common yet elusive health conditions of our time.

Today we're talking about the relationship between cancer treatment and exercise. For years, the standard advice for someone going through cancer treatment has been simple: just rest. The belief has long been that the body has to slow down and conserve energy to cope with the intensity of the treatment. However, recent research is challenging this long held notion. What if your body doesn't need to slow down - what if it actually needs to speed up? Today, I'm joined by Dr. Jessica Scott, whose groundbreaking research is reshaping our understanding of the best path to recovery for cancer patients.

Listeners will learn essential techniques, from proper form to breathing and injury prevention. Finally, we discuss what happens in the body post-workout and the importance of building a sustainable routine. Andy shares practical advice on nutrition, recovery, and how to create a strength training habit that delivers long-term results.

Last year, a study found that a third of Americans aged between 50 and 80 feel lonely. I'm sure most of us can relate to this feeling, and understand how a lack of social connection can take a serious toll on our mental health. But, is loneliness affecting more than just our minds? Does it also impact our physical health and how well we age? In this episode, Professor Rose Anne Kenny joined me to answer these questions and discover ways that we can foster meaningful relationships. She starts by telling us about her groundbreaking study into ageing in Ireland. 

Carbs are one of the most misunderstood aspects of nutrition. For decades, they've been praised, demonized, and debated. Today, low-carb diets are everywhere, but the reality is more nuanced. While over 80% of the carbs we eat come from low-quality, refined sources, the right kinds of carbs are essential for good health. In this episode, Professor Tim Spector breaks down the difference between good and bad carbs and explains why quality matters more than quantity. He explores how the rise of ultra-processed foods has led to an overconsumption of unhealthy carbohydrates, contributing to energy crashes, hunger, and long-term health issues. He also explains the benefits of fiber-rich carbs, their role in gut health, and why cutting carbs entirely may not be the best approach. The episode also answers common questions about carbs, including the best time to eat them, how to pair them for better digestion, and whether alternatives like almond flour are actually healthier. Tim also shares practical tips, such as why freezing bread might be a simple way to make it better for you.

In 2025, global spending on skincare products is expected to approach 200 billion dollars. It's an astonishing figure, but not entirely surprising when you consider the social value we place on this organ.  Our skin can reflect our age, health, and even our emotions. So, how can we make smarter choices this year and invest in products that truly support our skin? In this episode, I was joined by Sarah Berry alongside my wife, dermatologist Dr. Justine Kluk, to help us better understand this fascinating organ.

Could optimizing your sleep significantly extend your lifespan? In this episode, we dive deep into the science of longevity with Bryan Johnson, the entrepreneur spending millions to reverse aging, and Professor Tim Spector, one of the world's top 100 most-cited scientists and an expert in nutrition and the microbiome.

But how much of it is backed by science? Tim Spector joins the conversation to separate fact from fiction, revealing what actually works when it comes to sleep, longevity, and optimizing health.

Today we're considering mindfulness. Improving your health often comes with certain sacrifices. You might need to sacrifice time to exercise or money for specialised equipment and food. But mindfulness is different. It doesn't demand our time or cost money. Instead, it suggests we can enhance our health simply by changing the way we think. So, is it really possible to think our way to better health? And if so, where do we begin? In this episode, Harvard professor Ellen Langer joined me to delve into the magical connection between mind and body.

Are meat alternatives healthy? It's well known that many of us should reduce our red meat intake - and chances are, a lot of you already have. However, the craving for that meaty flavour - the desire to sink your teeth into a nice juicy burger can still linger. It's no surprise then, that supermarket shelves are now stocked with a growing variety of fake meat products. However, are these meat alternatives actually any healthier? Stanford Professor Christopher Gardner joins us to discuss his randomised control trial comparing the health effects of red meat against its plant-based counterparts.

Oatmeal has long been considered a heart-healthy breakfast, but is it really as good for us as we think? In this episode, Jonathan and Sarah break down the great oat debate. First, they explore the different types of oats - instant, rolled, and steel-cut and how processing impacts their nutritional value. Then, they put oats to the test using continuous glucose monitors (CGMs), comparing instant to steel-cut, with and without toppings, to demonstrate how blood sugar works. Sarah also discusses wider debates around oats: Are pesticides a concern? Is oat milk as healthy as it claims? Finally, she shares the ultimate guide to choosing the healthiest oats - and for those who prefer alternatives, she's got delicious, nutrient-packed swaps to try.

Today we tackle menstruation. Despite affecting half the world's population for a significant part of their lives, menstruation remains clouded by taboo. This lack of open conversation can leave women without the knowledge they need to address pain, discomfort, or irregularities associated with their period. So, what signs should raise concern when it comes to menstruation, and how can we manage symptoms effectively? Professor Sarah Berry and Dr. Jen Gunter join us to break the silence around menstruation.

Arthritis affects millions worldwide. 1 in 5 adults in the U.S suffer with it and many people assume it's an inevitable part of aging. Bu what if you could reduce joint pain and inflammation through diet and lifestyle? In this episode, Dr. Tamiko Katsumoto, Clinical Associate Professor at Stanford University, unpacks the science behind arthritis. She explains the key differences between osteoarthritis, caused by wear and tear on joints, and rheumatoid arthritis, an autoimmune condition where the immune system attacks healthy tissue. While there is no cure for arthritis, Tamiko reveals why chronic inflammation plays a central role - and how the modern diet is making things worse. Tamiko shares evidence-based strategies to reduce inflammation naturally, including the best foods to support joint health and whether supplements and lifestyle changes can make a real difference. If you or someone you know suffers from joint pain, this episode is packed with insights to help you take control of your health.

Today we're diving into coffee. Most of us are greeted by its earthy aroma every single morning. It's hot bitter taste signaling that the day has officially begun. Coffee is so ingrained into our daily routine we rarely pause to consider the effect of coffee on our health.  So, what is coffee, a health-boosting elixir or just another guilty pleasure? Coffee expert James Hoffmann joins us to explore one of the world's most popular drinks.

We spend so much time focusing on how exercise changes our bodies - burning calories, building muscle, shedding fat. What if the most important transformation is happening where you can't see it? Hidden inside your skull, your brain is changing with every step, squat, and sprint. Neuroscientist Dr. Wendy Suzuki has spent years uncovering how movement rewires the brain. As a professor at NYU and an expert in neuroplasticity, Wendy's research reveals how aerobic exercise boosts memory, sharpens focus, and even builds a protective barrier against dementia. In this episode, Wendy explains what happens inside your brain when you move, why it's never too late to strengthen your mind, and the powerful ways exercise can slow brain aging. You'll discover simple, science-backed habits - including her own brain-boosting routine - to help you stay mentally sharp for years to come.

Today we're talking about intermittent fasting. This form of time-restricted eating has been gaining significant popularity, with many people reporting positive effects after incorporating it into their daily routines. However, here at ZOE, we want to know what the science says about intermittent fasting. Is it the real deal? Or just another fad? I'm joined by Tim Spector and Gin Stephens to break down what intermittent fasting is, how it affects our bodies, and whether the scientific evidence supports it.

Midlife is often seen as a point of no return for health, but it could be the perfect moment to make a radical change. New research suggests that your gut microbiome holds the key to aging well, protecting you from chronic disease, and even reversing some of the damage from years of poor diet and stress. Few people understand this better than Rich Roll, who went from an overweight, junk-food-addicted workaholic to one of the world's fittest men - all after the age of 40. Now a plant-fuelled ultramarathoner and bestselling author, Rich shares the wake-up call that forced him to transform his life. He's joined by Professor Tim Spector, one of the world's top 100 most cited scientists and professor of epidemiology at King's College London, who explains why gut health becomes even more important as we age - and how small changes to diet, movement, and daily habits can have an outsized impact later in life.

Today we're discussing fat. It's a word that carries a lot of weight. It's a source of social judgment, a driver of insecurities and a tool exploited by companies in targeted marketing campaigns. It's no surprise that a recent study found over 40% of people in the US have experienced some form of ‘fat-shaming'. But do we really understand fat? What it does, how it forms and why its distribution changes as we age. Prof. Sarah Berry and Prof. Deborah Clegg are here to help us answer some of these questions and change our perception of fat. Deborah Clegg is a professor and Vice President for Research at the Texas Tech University Health Sciences Center, El Paso. Sarah is Chief Scientist at ZOE and Professor at King's College London. 

Only 12% of American adults are considered metabolically healthy - meaning the vast majority are at increased risk of heart disease, diabetes, and strokes. But what exactly is metabolism, and why does it matter so much for our health? In this episode, bestselling author and health expert Shawn Stevenson joins world-renowned scientist Professor Tim Spector to break down the science of metabolism. They'll debunk the myth of “metabolic rate” and explain why it's not just about how fast you burn calories - but how your body processes and uses them. You'll discover how poor sleep, stress, and ultra-processed foods are impacting your metabolic health - and how this sets the stage for weight gain and chronic disease. More importantly, Shawn and Tim will share the simple, science-backed habits that can improve your metabolism, from eating nutrient-dense foods to optimizing movement and sleep.

Today we're exploring what evolution can teach us about exercise. When it comes to doing exercise, there's often a tug-of-war between our body and brain. Our body craves movement - it wants to be leaner, fitter, stronger. But our brain? Well, that's a different story. It often dreads the thought of going on a run or lifting weights and will try and find any excuse to avoid doing it. So, why does this conflict exist, and more importantly, how can we overcome it? Harvard Professor of Biological Sciences Daniel Lieberman is here to unravel the mysteries of our exercising ancestors and explain how this can help us train today.

Dementia is one of the fastest-growing health crises in the developed world, with cases expected to double in the coming decades. But despite common misconceptions, cognitive decline isn't inevitable. The latest research shows that lifestyle choices play a far greater role in brain health than genetics alone. In this episode, neurologists Drs. Ayesha and Dean Sherzai share practical, science-backed strategies to help you protect your brain and reduce your risk of dementia. As co-directors of the Alzheimer's Prevention Program at Loma Linda University, they've spent their careers studying how habits like diet, exercise, sleep, and stress management influence long-term cognitive health.

Today, we're putting the spotlight on our brains. As we age certain behaviours often become more noticeable - misplacing keys, struggling to recall names or forgetting why you walked into a room. Most of us have likely seen this happen to someone close to us and may have even seen these patterns develop into more serious conditions like dementia. But are these behaviours just an inevitable part of getting older? Or is there something we can do to prevent them? Dr William Li is here to outline the connection between our lifestyle and the health of our brain.

How old are you? A better question might be: how old do you feel? While your birthday says one thing, your biological age—the health of your cells—might tell a very different story. And here's the best part: unlike your chronological age, your biological age can go down. But how? For years, fasting has been celebrated as a key to longevity. Yet the challenge of skipping meals is enough to make most of us shy away. What if you could trick your body into reaping the rewards of fasting—without starving yourself?  This week, we're joined by Dr. Valter Longo, Director of the Longevity Institute at USC and one of TIME's 50 most influential people in healthcare. Valter's groundbreaking research on ageing and his FMD program have transformed how we think about health and longevity. Joining him is Tim Spector, ZOE's co-founder and one of the world's top 100 most-cited scientists.

Today we're discussing inflammation. We hear this word a lot from guests on the ZOE podcast. It's always coming up when we ask questions about health conditions like Alzheimer's, cancer or heart disease.  It's clearly very important, however many of us still don't fully understand what inflammation really is. Professor Phillip Calder is here to break down inflammation and share tips on what we should eat to keep it in check. Philip is Head of the School of Human Development and Health in the Faculty of Medicine at the University of Southampton.

Think weight loss is all about eating less and moving more? Think again. In this episode, Prof. Giles Yeo reveals why calorie counting isn't just inaccurate—it could actually make weight management harder. He explains why the popular “calories in, calories out” method doesn't add up and explores how factors like genetics, brain signals, and gut health play a major role in shaping our weight. Giles Yeo is a Professor of Molecular Neuroendocrinology at the University of Cambridge and Honorary President of the British Dietetic Association. His research focuses on the influence of genes on feeding behaviour and body weight. Giles is also the author of ‘Gene Eating' and ‘Why Calories Don't Count'. Giles shares the surprising impact of ultra-processed foods on how we process calories and why losing weight often feels like a battle against our own biology. With decades of research in his back pocket, Giles shares science-backed advice to help you break free from yo-yo dieting, read calorie labels smarter, and embrace a more balanced, plant-rich diet for long-term health.

A lot of things change as we age. Our dress sense, our taste in music and importantly our body. The truth is your body is not the same as it was 20 or even 10 years ago.  So why should your diet be? Dr Federica Amati is here to explain why our nutrition needs change as we enter later life and how we can adjust our diet to support this.

So, how can you adjust your workout routine to best support your body through this change? Exercise physiologist Dr. Stacy Sims tells us how we can optimise fitness during this unique stage of life.

Artificial sweeteners are everywhere. They hide in cereal, salad dressing – even in health foods. But are they really a guilt-free way to satisfy your sweet tooth? Or is it naive to think that – because they're zero calorie – they're free of consequence? New research shows there is a consequence. And it could be massive. Artificial sweeteners may disrupt the delicate balance of bacteria that live in your gut. You could see ripple effects like chronic disease, weight gain and a weakened ability to process real sugar. Today's guest is at the forefront of this research. For the last decade, Dr Eran Elinav led breakthroughs on the science behind popular sweeteners. He leads The Institute for Microbiome Research at the Weizmann Institute of Science. He's published over 100 publications in leading scientific journals. And his lab is on the cutting-edge of gut microbiome research.  We're also joined today by Tim Spector. Tim is one of the world's top 100 most-cited scientists, a professor of epidemiology, and my scientific Co-Founder at ZOE.  You'll finish today's episode knowing what's in your sweetener, how it's affecting you, and where to turn to satisfy your sweet tooth.

Sarah is a world leader in large-scale human nutritional studies, associate professor in nutrition at King's College London and Chief Scientist at ZOE. 

How strong is your skeleton? It's a tough question - and often, we only find out the answer when a bone breaks. The reality is, many of us have weak bones. Osteoporosis affects one in four people over fifty, significantly increasing their risk of painful and debilitating fractures. So, what can you do to keep your bones strong as you age? Professor Tim Spector & Professor Cyrus Cooper explain how you can tailor your lifestyle to maintain a strong skeleton.

We waste a shocking 40% of the food we buy. We throw away foods like carrot tops, beet greens, and spent coffee grounds. These ‘food scraps' stuff our landfills and drain our pockets. But we can eat these foods and many of them offer tons of healthy nutrients. Today's guest is Carleigh Bodrug. Carleigh's published a best-selling cookbook with over 140 recipes made from food scraps you might otherwise throw away. Her mission is simple: eat more plants. Her online community, PlantYou, has more than 10 million followers. She's joined by Dr. Will Bulsiewicz. Will is a board-certified gastroenterologist and ZOE's U.S. Medical Director.

You'll walk away from today's episode saving your money and the planet, all while eating more plants.

Stress can come from any direction. Mounting deadlines at work, a romantic tiff at home, even something as simple as missing our bus can send our brain and body into a state of tension. We all experience this, it's nothing new. However, our failure to manage this stress could be harming our health. Dr Rangan Chatterjee is here to give us some strategies to combat stress, reduce tension and keep us healthy.

The heart is at the centre of everything within our bodies, constantly pumping oxygen and nutrients throughout our tissues and organs. We all know if our heart fails, we're in trouble. However, we only tend to start thinking about the health of our heart when we encounter a problem. So how do we prevent a problem from occurring? Dr. Peter Attia joins us to explain how making changes to our lifestyle today can help us take control of our heart health tomorrow.

1 in 3 people have anxiety. It's the most common mental health disorder in the world.

It's not just in your head, it's in your gut. Today, we'll learn how food could help us cope. Our guest explains the rising global trend toward increased anxiety: its rise through the pandemic, and explosion among young people.  Dr. Uma Naidoo is on the forefront of nutritional psychiatry. She directs the first hospital-based Nutritional Psychiatry Service in the US, at Massachusetts General Hospital and teaches at Harvard Medical School. Uma will help you understand the symptoms and biology of anxiety, painting a picture of the risks it poses for long-term health. And her diet tips will help you fuel your gut for a healthy mind.

Today we're discussing how the food we eat can lower cholesterol. It's an important question, as high cholesterol can increase our chances of developing heart disease. Around half of adults have high cholesterol, and it gets more common as you age. So, how can we break this trend? Today's guest, Professor Sarah Berry has led more than 30 human studies on cardio-metabolic health. It's safe to say she knows a thing or two about heart health and cholesterol.
