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.

A good gynecologist is like a detective. She gathers evidence to diagnose infections. She uncovers the truth behind stages like puberty, pregnancy and perimenopause. Yet many women still feel that their physiology is a mystery.  What if a clue to that mystery hides in our diet? Similar to the gut, certain foods make the vaginal microbiome thrive. New research suggests that the right diet could alleviate symptoms of the most common gynecological diseases. Dr Jennifer Ashton is former Chief Medical Correspondent at ABC News and is a double-board certified OBGYN. She joins us today to discuss ‘nutritional gynecology’, a term she coined after realizing multiple women’s health issues have a direct relationship to nutrition. Alongside Jen is King’s College London professor and ZOE’s Chief Scientist Sarah Berry. Sarah shines light on the growing evidence of the role of nutrition in offsetting uncomfortable, and sometimes dangerous, symptoms of menopause. 🥑 Make smarter food choices.

Did you know you can now buy ice cream with added protein? Even breakfast cereals are jumping on the trend, boasting an extra protein punch. In nearly every supermarket aisle, you'll spot the catchy slogan "high in protein" plastered across packaging. But why is that?

Over the last two years, there’s been a rise in “immune-boosting” foods, supplements and trends. Today's guest, immunologist Dr. Jenna Macciochi, believes the immune system doesn’t need boosting.

Jenna highlights the case for the ‘good bugs’ in our gut microbiome, the role of micronutrients and how our immune system isn’t born, but made.

Today, we hear from two of the UK’s most-trusted nutritionists (and both parents of small children) on how to keep your kids eating well.  Rhiannon Lambert has authored four books, including recent Sunday Times bestseller The Science of Plant-Based Nutrition.

Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm. As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer. Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center.

Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health. Today, we’re talking about the century-old paradigm of weight management — calorie counting. Rooted in the law of thermodynamics, the notion is simple: Consuming fewer calories than expended results in weight loss. While seemingly straightforward, the practical application of calorie counting can prove challenging, with many of us underestimating our calorie intake or finding it difficult to maintain this diet long-term. In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center.

Today, we’re talking about the paleo diet, rooted in the idea of emulating our hunter-gatherer ancestors after concerns about the impact of a modern westernized diet packed with highly processed foods. However, the diet often involves consuming increased amounts of saturated fats, primarily from meat. This is associated with heightened cholesterol levels and heart disease risk. In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center. Together, they dissect the diet’s potential benefits, pitfalls, and sustainability.  🌱 Try our new plant based wholefood supplement - Daily 30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system Learn how your body responds to food 👉 zoe.com/podcast for 10% off Timecodes: 00:00 Introduction 00:42 Topic intro 02:05 Is the paleo diet a logical diet based on where we came from? 03:03 What’s so appealing about the stone age diet? 04:19 What’s the difference between paleo diets now and our authentic ancient diets? 05:30 What are the theoretical health benefits if you were to follow the paleo diet? 06:32 What are the downsides of following the paleo diet? 07:09 How closely does the ancestral paleo diet match our modern paleo diet? 09:25 What's the verdict? 10:04 Outro Have feedback or a topic you'd like us to cover?

Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health. Today we’re talking about the low-fat diet, popularised in the 1970s and fueled by the belief that fat was the culprit behind heart disease and weight gain. However, the aftermath saw a surge in low-quality carbs. Food manufacturers, in the quest for low-fat options, replaced fats with sugar and refined grains, resulting in us opting for low-quality carbs over whole foods and whole grains. In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, a professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center.

There’s been a surge in our consumption of ultra-processed foods, especially in the United Kingdom and the United States, where these foods contribute about two-thirds of people’s caloric intake. Also a cause for concern is emerging evidence of ultra-processed foods’ detrimental effect on our brain health and overall well-being. When most of our calories come from ultra-processed foods, the risk of chronic physical and mental health conditions escalates. Scientists are now uncovering the intricate mechanisms behind this relationship, particularly concerning the effects of these foods on our brains. In today’s episode, we welcome back Prof. Felice Jacka, OAM. Felice is an Alfred Deakin professor of nutritional psychiatry and the director of the Food & Mood Centre at Deakin University, in Australia. She’s also the founder of the International Society for Nutritional Psychiatry Research and the world’s leading researcher on food’s impact on our brain and mental health.

Unfortunately, many of us spend our later years in poor health. But is this avoidable? And can we actually increase our healthy years?

Simply spending time with others can provide countless benefits to us as we age. But how can we maintain these connections? Does retirement affect our social interactions? And can attitude alone keep you healthier in your later years? In today’s episode, one of the world’s top experts on aging, Prof. Rose Anne Kenny, joins us to explore these ideas.  Rose Anne is a world-leading geriatrician at Trinity College Dublin, where she leads a huge, long-term study on aging.

Decades ago, there were reams of adverts instructing us to drink our milk so we don’t break our bones. But in the decades since, public opinion toward dairy is very different, and the scientific community has largely debunked these ideas.  Many of the health-conscious among us choose to avoid it altogether. Our reasons range from a belief that dairy leads to inflammation, to acne, or even to an increased risk of heart attack due to high levels of saturated fat.  But have we fallen into the same trap we often do, bouncing from one extreme to another? Could cutting out dairy mean we miss out on vital nutrients? Or could it hold the secret to a healthy gut microbiome? Today, Jonathan is joined by ZOE regulars and renowned experts, Dr. Sarah Berry and Prof. Tim Spector. In this episode, you’ll not only find out whether you should eat dairy or cut it out, but you’ll also hear two leading nutritional scientists try to reach an agreement on how to translate the latest research into actionable advice. And hopefully, they’ll still remain friends afterward.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00 - Intro 00:13 - Jonathan’s Intro 01:38 - Quickfire round 02:45 - Biggest myth about dairy 04:15 - Does dairy cause inflammation?  10:38 - Bone fragilaty 16:03 - Cheese and Yogurt 16:59 - Full fat vs semi skinned 17:27 - Milk and cholesterol 21:03 - Fermented dairy 23:00 - dairy and microbes 26:03 - Saturated fats 26:51 - Cheese quality  31:15 - Summary 33:03 - Goodbyes 33:14 - Outro Follow ZOE on Instagram.

As we age, our bodies undergo numerous changes, including a decline in muscle mass and cognitive function. For many of us, exercise and diet play crucial roles in maintaining our health and well-being.  But how can the protein we eat affect our abilities to exercise and stay healthy as we age? It can be difficult to separate fact from fiction when it comes to the effects of protein. How much do we need? Is it better to eat protein before or after exercise? And what roles do protein and exercise play in brain function? In today’s episode, Jonathan is joined by Prof. Ben Wall, an expert in nutritional physiology at the University of Exeter. Together, they unpack the latest scientific research on the connection between protein consumption and exercise. Prof. Ben Wall shares his insights into the optimal amount and timing of protein intake for building and maintaining muscle mass, as well as the potential impact of exercise on cognitive function and brain health into later life.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:12 Introduction 28:21 Quick Fire Questions 02:54 Do we need to eat proteins right after exercise? 03:34 What is protein? 04:45 Why should we care about exercise? 05:36 How does exercise help with healthspan? 07:41 What are the benefits of exercise? 07:57 Does exercise improve brain function? 11:23 Where do our muscles come into this conversation? 12:09 What constitutes an unhealthy muscle? 13:00 What's the difference between a healthy and unhealthy muscle? 14:18 How does protein fit into the idea of healthy muscles? 16:03 What about the concept of breaking muscle.

We’ve probably all been reprimanded for eating too fast at the dinner table or suffered the dreaded “itis” from eating way too much food at a family gathering. Our society and the systems we’ve developed to feed it have ballooned to such a point that they easily override our natural bodily systems that tell us when we’ve had enough to eat.  When nearly 50% of the United States population is projected to have obesity by 2030, can something as simple as changing the speed with which we eat really be an effective tool for weight loss and sustaining a healthy body? In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: What is eating rate and does it have any impact on our health?

Menopause is a time of significant hormonal changes which can lead to a range of symptoms that can severely impact quality of life for many women. So, a drug that promises to reduce these symptoms is incredibly welcome, but it has been steeped in controversy. HRT (Hormone replacement therapy) has been widely debated, with conflicting information about its effectiveness, with some suggesting HRT is outright dangerous. In fact, a massive study twenty years ago linked it to an increased risk of breast cancer. As a result, the numbers of women taking HRT plummeted. So should HRT be avoided at all costs?  In today’s episode, Jonathan is joined by the author of that very study and esteemed Professor JoAnn Manson, alongside Dr. Sarah Berry to explore the science behind HRT. Professor JoAnn Manson is a professor of epidemiology at the Harvard School of Public Health and one of the world's most experts on HRT and menopause having run multiple enormous studies to uncover the effects of hormone replacement therapy on women’s health. With the help of ZOE regular Dr. Sarah Berry, they delve into the science behind HRT, empowering listeners to make informed decisions about treatment for symptoms of the menopause.

Proteins, carbs, and fats … most people understand what the last two are. Carbs are sugars, and fat is, well, fat. It's protein that’s so important to our diets, but so often misunderstood — by the general public, that is. Since the 1950s and 1960s, scientists have been measuring how protein affects our performance, how it supports and maintains the body’s structure, and how best to incorporate it into our diets.  From big steaks to protein shakes, tofu to seitan, protein is more available now than ever before. With so many options, surely we’re getting enough protein?  In today’s episode, Jonathan speaks with a leading nutritional researcher to find out. Christopher Gardner is a professor at Stanford University and a member of ZOE’s scientific advisory board. He’s pioneering the movement to redefine how we understand the quality of our protein intake.

A miracle weight loss drug that’s approved in the US and the UK and has few side effects? Ozempic is going viral on social media. Users are posting dramatic before and after pictures of their weight loss. An Ozempic trend is allegedly blossoming in Hollywood, and famous personalities like Elon Musk claim to have taken it.  Many remain doubtful, dismissing the craze as just another internet scam preying on people’s insecurities. However, earlier this month - semaglutide - the drug’s active ingredient, was approved as a weight loss treatment by the UK’s National Health Service. Even the most sceptical are taking note. Jonathan speaks to Dr Robert Kushner the lead investigator of the huge phase 3 clinical trial that evaluated the safety and effectiveness of semaglutide. He is a founder of the American Board of Obesity Medicine and hailed the drug as a ‘game-changer’ in regards to the treatment of obesity. Please be aware: Dr. Kushner is also a consultant on the medical advisory board for Novo Nordisk - the company that manufactures semaglutide.

If you were to ask Siri, Alexa, or ChatGPT for medical advice right now, that would be a terrible idea.  But with recent developments in technology, this looks set to change. AI has become more intelligent, wearable devices - more accurate, and personalized medicine - increasingly mainstream. But is any of this safe? Should we really trust machines with our health? And will any of this actually happen? In today’s episode, Jonathan speaks to Eric Topol to explore how artificial intelligence may transform your next trip to the doctor.

The formal definition for constipation is ‘Having fewer than three bowel movements per week’. But, did you know that you can have a bowel movement every day and still be constipated? Recent data has shown that a quarter of people worldwide have at one point reported symptoms, suggesting that there is so much more to constipation than simply infrequent bowel movements. In today’s short-ish episode of ZOE Science & Nutrition, Jonathan and Will attempt to dispel some misconceptions about constipation and empower you to have better bowel movements.   Studies referenced in today’s episode:  A redefinition of constipation by King’s College London, published in the American Journal of Gastroenterology (2019) here The State Of The Nation’s Gut, Love Your Gut here Epidemiology of constipation in Europe and Oceania: a systematic review from Prichard & Bharucha via BMC Gastroenterol here Recent advances in understanding and managing chronic constipation from Peppas, Alexiou, Mourtzoukou & Falagas via F1000Research here Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Follow ZOE on Instagram: https://www.instagram.com/zoe/ Follow Sarah on Instagram: https://www.instagram.com/theguthealthmd/  This podcast was produced by Fascinate Productions.

The cost of living has soared. Energy prices have doubled, and food costs have gone up enormously. As a result, the weekly shopping bill can be shocking.  For some, this is merely an inconvenience. But many others face the awful choice between heating their home and maintaining their usual diet. The consequence is that many of us are throwing cheaper ingredients into our shopping baskets to save money.  So does this mean that eating healthy is an indulgence that be dropped in favour of cheap ultra-processed food? Or is it still possible to eat healthily on a budget? In today’s episode, Jonathan speaks to Dr. Rupy Aujla and Tim Spector to better understand how to eat healthier while spending less: Dr. Rupy Aujla is a medical doctor who, since 2015, has been teaching people to cook their way to health. He’s the founder of The Doctor’s Kitchen and has recently turned his efforts to healthy cooking on a tight budget.

Our gut helps fight disease. It processes energy for us and boosts our mood. So, having a healthy gut is extremely important – but there’s still a lot we don’t know. Gut biome tests are a new, exciting technology, but are they the be-all and end-all for dietary decision-making? And are there simpler ways — and tastier ways, perhaps — to tell what’s happening inside our bodies? In today’s short episode of ZOE Science & Nutrition, Jonathan and Dr. Will ask: What are the signs of an unhealthy gut? And how can we improve our gut health?

Blood sugar is one of the rare nutrition topics where everyone agrees: We should avoid big peaks and dips and aim for a steady curve.  Spikes cause inflammation, accelerate aging, and lead to type 2 diabetes. Crashes make us feel moody and tired, and crave foods we don’t need.  We can control our blood sugar through what and how we eat. But something else affects our blood sugar — physical activity. Exercise has a profound effect on your blood sugar response. Together with your food choices, being physically active helps you keep your blood sugar level even. In this episode of ZOE Science & Nutrition, Jonathan speaks with Javier Gonzalez and Sarah Berry to find out how exercise affects our blood sugar response — even when we’re fasting — and how much exercise we need to do to benefit. Javier Gonzalez is an associate professor of human physiology at the University of Bath whose research focuses on the interaction between diet and exercise. Sarah Berry is one of the world's leading experts on human nutrition. She has personally run over 20 randomized clinical trials looking at how humans respond to different fats.

This year, cases of an invasive bacterial infection are rising earlier than usual in the US, the UK and other countries across Europe.  The group A Streptococcus bacteria - commonly known as Strep A - usually only causes mild illness. However, things have become severe in some cases, with several children dying in recent weeks. So, should we be worried? And what symptoms should we look out for to help us identify this illness in ourselves and our families? In today’s episode, Jonathan is joined by world-leading expert on the subject: Shiranee Sriskandan is a professor of Infectious Diseases at Imperial College London whose scientific research focuses specifically on Strep A bacteria. Regular guest and ZOE co-founder Tim Spector also joins, and as one of the world’s top 100 most cited scientists, Tim has been closely following infectious diseases in the community through the ZOE Health Study.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00   Introduction 00:10   Topic Introduction 01:40 Quickfire Questions 03:15 What is Strep? 04:04 How common is Strep? 05:02 Seasonality of Strep and symptoms in different climates 05:30 What makes this year different? 06:31 Can Strep make other illnesses worse? 07:07 We've already seen signs of Strep rising over time, is this due to lockdown? 09:36 How worried should we be about Strep infections? 10:10 Group A Strep will often get better on its own 11:07 The risk of rarer invasive infections is greater as the pool of cases increases 11:59 Immune response to Strep A can increase chances of Rheumatic Fever 13:35 What is Rheumatic Fever? 14:59 What are the symptoms of Strep A 16:53 How to treat Strep Throat 18:12 What is the relationship between Strep A and Scarlet Fever 18:53 Who gets Scarlet Fever and what are the symptoms? 19:34 What are the distinguishing features between covid and other sore throats 20:53 Do children get more fevers if they are younger? 22:54 What to do if you think your child has strep throat 24:01 Can you get rapid tests for Strep A? 24:25 Why has Strep throat been seemingly more prominent in the US than the UK 25:41 Different health services around the world and their respective responses to Strep 27:36 Should we be testing and treating? 30:15 What role does differing attitudes to healthcare play in this? 32:02 Should we be cautious about using antibiotics for Strep A? 33:51 What potential problems are there around antibiotics? 36:00 Would a vaccine be the answer to stopping Strep in its tracks? 38:41 Tim's top tips to boost your immunity this winter 41:06 Summary Episode transcripts are available here Read about Tim Spector’s ZOE Health Study here Follow ZOE on Instagram: https://www.instagram.com/zoe/ Have an idea for a podcast?

The last decade saw a rise in gluten-free diets. But the number of us with diagnosed gluten intolerance each year hasn’t changed. Eliminating gluten is the only treatment for those with celiac disease, but the rest of us could be doing more harm than good by embracing ultra-processed, gluten-free foods.  In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: Should you be worried about gluten?

We all know how good it feels to drift into deep sleep and wake up feeling refreshed.  The positive effects of a good night’s sleep affect every aspect of our lives. We feel energetic, focused, and ready to take on the day’s challenges.   But the long-term effects of bad sleep are less known. It turns out, they have a huge impact on our health and even how long we live.   In this episode, Jonathan speaks with Prof. Matthew Walker to learn what the latest science says about improving our sleep — to give us more energy and better health. They also discuss whether how we sleep changes how our bodies respond to food. Matthew Walker is a sleep expert, a professor of neuroscience at UC Berkeley, and founder of the Center for Human Sleep Science. He’s also the author of Why We Sleep.

The acid in your stomach is so powerful it can dissolve metal. Luckily, your stomach is fine-tuned to deal with its acidic fluid, but the rest of your body isn’t quite as hardy.

The symptoms vary significantly from person to person, including sleep problems, hot flashes, weight gain, and an increased risk of heart disease.  In one of the largest studies to date, ZOE researchers have uncovered a link between menopause and our diets — and this could hold the key to reducing the severity of menopause symptoms.  In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: what role does diet play during menopause?  Follow ZOE on Instagram: https://www.instagram.com/zoe/ Follow Sarah on Instagram: https://www.instagram.com/drsarahberry/  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Studies referenced in the episode:  ‘Why we are all being let down by the lack of research into menopause’ from Mosaic here ‘Menopause’ from the Nature Reviews Disease Primers here ‘What is Menopause?’ from the National Institute of Aging here This podcast was produced by Fascinate Productions.

In a lab in Ireland, a group of scientists stand around a stainless steel table. One of them is holding a device, not unlike a small turkey baster. His free hand plunges into a box on the table and retrieves a mouse.   Using his device, he administers the brown solution within…rectally.  This unfortunate soul has just received a fecal microbiota transplant. The donor was not another mouse but a human being. And the person in question had symptoms of severe depression.  Jonathan speaks to John Cryan, author of the study that showed a relationship between gut and brain.

Fermentation is a hot craze in fancy restaurants around the world. And fermented foods, like kombucha and kimchi, are even sold in corner stores.  Listeners of this show will have heard that fermented foods might benefit our gut health. But these foods make us uneasy. The idea of letting food rot, then eating it goes against everything our parents taught us. So, is fermentation scary and dangerous?  This episode will show you why it's not only safe but beneficial to eat fermented foods, and that fermenting foods is something you can try at home.  Jonathan speaks to Tim Spector and Sandor Katz — whom the food magazine CHOW calls a provocateur, trendsetter, and rabble-rouser — to better understand the fabulous world of fermentation.  Sandor Katz is a food activist who is widely credited with reintroducing fermentation to the US and the UK, calling himself a fermentation revivalist. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.

Fasting has been shown to improve our metabolism, slow disease and potentially increase our life span. While world religions have practiced fasting for millennia, the trend of fasting has soared in popularity in the last decade.  Not all fasts are made equally and there are a lot of different rules to follow. Some purists argue that you’re only allowed water while fasting others believe there can be more flexibility during your period of abstinence.  In today’s daily episode of ZOE Science & Nutrition, Jonathan is joined by Tim Spector to answer the question: what breaks a fast?  This episode is part of a limited series to celebrate the launch of The Big IF Study: The world’s biggest clinical study to discover how intermittent fasting affects our mood, energy and hunger levels.  Want to know if intermittent fasting can work for you?  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide TAKE PART for FREE: joinzoe.com/thebigif This podcast was produced by Fascinate Productions.

It seems like every day, someone new mentions intermittent fasting. But what is it, exactly?  There are myriad options — from the 5:2 diet, with two days of extreme calorie restriction each week, to the warrior diet, which involves eating only raw fruit during the day and a mammoth feast at night. Whatever the approach, intermittent fasting involves restricting the window of time when you eat. Supporters evangelise the benefits, promising weight loss, disease prevention, and even life extension.  Currently, the scientific evidence is unclear, but it's an exciting area that may be full of potential.  Today, Jonathan speaks with Gin Stephens, who has had a powerful experience of intermittent fasting transforming her health and weight. He also talks to Tim Spector, who will share what science can tell us about intermittent fasting today —  and, interestingly, how much it can’t, yet. Plus, an exciting announcement about how this is set to change. Gin Stephens is a New York Times bestselling author and podcast host.

Do our blood vessels hold the secret to long life? 60,000 miles long. That’s the length of the tube system inside us that transports blood, oxygen, and nutrients to the cells in our body.  If these tubes fail, the result can be fatal. In some cases, it’s a heart attack. In others, it’s a stroke, where the blood supply to the brain is disrupted, and brain cells are damaged or killed.  Heart attacks and strokes are a major cause of death in developed countries - but we can take action to reduce the risks.  In this episode, Jonathan speaks to a world-renowned physician, scientist, and speaker to gain insights into how looking after this magical pipework could slow down aging.  Dr. William Li is a world-leading specialist in blood vessels and preventative health and the author of countless papers on the topic, who possesses the gift for communicating this complex subject in terms we can all understand.

Our planet is overheating. Human society is creating too much carbon dioxide, stopping the sun’s warmth from escaping back into space. As earth gets hotter, its ice caps are melting, causing sea levels to rise, and submerging entire communities. Floods, droughts, and wildfires are already becoming much more common. Some effects of climate change are now irreversible, but there is still hope, and adjusting what we eat might play a bigger part than you’d imagine. In this episode, Jonathan speaks with a pioneer in science who will help you understand how your eating habits affect the planet, so you can make informed decisions about the foods you eat and how you prepare them. Sarah Bridle is a professor of food climate and society at the University of York in the United Kingdom.

In today’s world, we increasingly live our lives late into the night. Whether it's work obligations, socializing, or being glued to a screen, we ignore the sun's rise and fall.  But most of us are unaware that a clock is ticking away inside us.  It uses light to keep time and tells us when to sleep and eat. Should we listen? Or is this biological clock simply a relic from a past time? In today’s episode, Jonathan speaks to a leading authority to unravel the latest science that reveals that this body clock, or circadian rhythm, has a dramatic impact on our health, weight, and mental wellbeing: Russell Foster is an Oxford University scientist who has dedicated his life to studying circadian rhythms.

Kanchan Koya grew up in a house filled with wonderful fragrances from the spices simmering on her grandmother’s stove. In India, it was a common belief that spices were more than just pleasant tastes. Ancient wisdom said they had medicinal properties, and it was common for household medicine cabinets to store dried spices, not pills. Kanchan grew up to become a molecular biologist, studying in the US at Harvard Medical School. When her lab began to investigate turmeric’s healing properties, the ancient wisdom from her childhood met the scientific inquiry of her adult life - beginning a lifelong obsession with the health benefits of spice.    In today’s episode, Kanchan and regular guest Tim Spector help us understand whether there is any scientific evidence to support the health benefits of spices, the easiest way to add spice to our diet, and which ones to choose. Kanchan Koya is the founder of SpiceSpiceBaby and The Radical Vitality Podcast with a Ph.D. in Biomedicine from Harvard University and training from the Institute of Integrative Nutrition.

We’ve all felt the effects of food on our mood, so it would stand to reason that dietary intervention for mental health would be well studied and a regularly deployed treatment.  But this is far from reality, as historically, psychiatry was only concerned with what happened from the neck up. In today’s episode, Jonathan is joined by Felice Jacka, Professor of Nutritional Psychiatry and Director of the Food & Mood Centre at Deakin University. Felice was the driving force behind the landmark study to determine if dietary intervention could help treat the symptoms of moderate to severe depression.  With her help, we dive into what the science suggests regarding the relationship between food and our mental health and what foods we can eat to improve it.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00 - Intro 00:09 - Jonathan’s introduction 01:28 - Quick-fire questions 02:08 - What do we mean when we talk about 'mood'? 03:40 - Is it true that we're much more focused on mental health?  05:11 - How do we think about the relationship between our bodies and our mind today? 07:01 - Felice’s journey into psychiatry  08:24 - PHD looking into the relationship between diet and mental health 11:44 - The SMILEs Trial 13:22 - How much did diet affect the participants in the study? 15:40 - How long does it take to see results? 16:40 - What role does body weight have in this debate? 17:22 - How important is it that we focus on the quality of our diet over calories?  18:20 - What is the gut-brain axis and the microbiota gut-brain axis? 19:12 - Gut disorders and mental health issues closely related 21:25 - The effects of gut bacteria on the brain 21:58 - What is orthorexia and how is that linked to anxiety? 23:16 - Is there a risk with using diet to treat mental illness? 24:20 - What do healthy diets from across the world have in common? 25:52 - Foods to eat more of or less of to improve mood 27:24 - Diversity in diet 29:12 - Effects of diet on the menopause 32:10 - How does our mental health affect how we eat? 33:20 - What part does the industrialized food system have to play on a social level? 34:14 - How ultra-processed foods impact us 37:06 - Summary Episode transcripts are available here.

Keto has been promoted as a magic bullet for weight loss by its supporters and slammed as dangerous by its opponents. It's no surprise - completely removing almost all carbohydrates is not what most people consider ‘a balanced diet’. With carbs off the table, Keto diets involve a dramatically increased fat intake. At the same time, drastically reducing carbs means starving our gut microbes of the fiber that feeds them.  Nonetheless, doctors prescribe keto diets to treat people with severe diabetes and see dramatic improvements, and many healthy people swear by keto for weight loss. On top of this, removing carbohydrates prevents blood sugar spikes and crashes linked to inflammation and disease.  In today’s episode, Jonathan speaks to a leading nutritional researcher to understand whether or not keto diets are a crazy fad: Christopher Gardner is a professor at Stanford University and a member of ZOE’s scientific advisory board who’s produced a clinical trial of keto diets, published in the American Journal of Clinical Nutrition.

The word ‘processed’ has become synonymous with being unhealthy. The mainstream media encourages us to detox from processed food or offers us ‘10 easy ways’ to stop eating it.  But nearly everything we consume has undergone some type of processing. In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: If most of what we eat is processed, can it really be that unhealthy for us?  Follow ZOE on Instagram: https://www.instagram.com/zoe/ Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide This podcast was produced by Fascinate Productions.

From blueberries to salmon, kale to acai, it seems like anything and everything can be classed as a superfood these days. Supposedly they can prevent cancer, reduce inflammation, and even help you live longer… In today’s short episode of ZOE Science and Nutrition, Jonathan and Sarah look at the history of superfoods and ask: are some foods really more ‘super’ than others?

It’s a biological process that we need to stay alive. Yet too much of it leads to disease and a shorter life.  Inflammation is the immune system’s response to an outside event it thinks is dangerous. This stimulus could be an injury, like falling off your bike or an infection by a virus or bacteria. But inflammation can also be triggered by our food in the hours after we eat.  But if this natural process is required to protect us from infections and injuries, why is inflammation usually cast in a negative light? Is there something behind this, or is the idea that inflammation is bad a lie, designed to sell magic potions with dubious evidence?  In today’s episode, Jonathan speaks to two show regulars to unravel all the information about inflammation: Dr. Sarah Berry is one of the world's leading experts on human nutrition, who has personally run over 20 randomized clinical trials looking at how humans respond to different fats. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.

It’s no exaggeration to say that bread shaped modern humanity - it was the cultivation of wheat for flour that transformed our ancestors from hunter-gatherers to city dwellers.  Today, millions of us start the day with a slice of toast, and most lunches in the US and UK are wrapped in a slice of bread or a burger bun as a cheap, flexible, and delicious energy source. But modern industrial processes designed to reduce the time and cost of baking mean today’s bread would be unrecognizable to our ancestors.   Today’s bread tastes good but has lost most of its nutritional content. With most of its fiber gone, and no time for bacteria to work its fermenting magic, bread has become a simple starch, rapidly turned into sugar in our blood and offering little to support our gut bacteria. For this reason, bread is increasingly demonized as an evil carb. In today’s episode, Jonathan speaks to two authorities on the subject to ask: Can bread can ever be healthy? Vanessa Kimbel is a specialist in personalised bread and her doctorate in nutrition & digestabilty of bread is in Baking as Lifestyle Medicine & preventative healthcare. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.

Coffee’s earliest consumption dates back millennia when the tribesmen of Ethiopia used its ground-up berries to help aid concentration during prayer.  Arriving in Europe in the 17th century, Coffee quickly began to replace beer and wine as a favourite breakfast drink.  In the 20th century, coffee was blamed for high blood pressure and heart attacks, and more recently linked to a rising epidemic of poor sleep.  None of this has prevented coffee’s relentless rise. Over 2 billion cups of the stuff are drunk each day.  So, is coffee a guilty treat as many of us suspect? Or is it a health drink feeding your good gut bacteria?  In this episode, Jonathan speaks with James Hoffmann and Tim Spector to find out. They discuss how coffee affects your gut bacteria, your hormones and your heart, whether decaffeinated coffee is healthy, and discover some of coffee’s most surprising side effects – which could come in handy if you find yourself in the jungle. James Hoffmann is a leading coffee expert and author of the World Atlas of Coffee and co-founder & chairman of the Square Mile Coffee Roasters. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.

You may have heard there are bugs in your gut. But do they matter?  Today, the evidence shows the answer is a resounding yes. This ecosystem of tiny microbes living in our bodies is one of the most exciting areas in medical research, linked to everything from metabolic to mental health. So while many of us have heard that gut health is essential, few of us understand why and what we should do to support our gut bacteria. In this episode, Jonathan speaks with Will Bulsiewicz to find out when our microbiome begins to form, the most effective ways to support our gut health, and the role these gut bacteria play in controlling our weight. Will Bulsiewicz is a board-certified gastroenterologist, and New York Times bestselling author of the microbiome book Fiber Fueled.

Today we’re talking about fat, a delicious component of our food with a terrible reputation.   Fats have been broadly associated with weight gain and heart disease until recently. A mountain of new scientific evidence suggests this is wrong and that it's not as simple as ‘all fat is bad’. Indeed, eating more healthy fat might actually reduce heart disease for many people.   In today’s episode, Jonathan speaks to Dr Sarah Berry to learn about what science tells us today, whether it is possible to lose weight on a high-fat diet, what oils we should be cooking with, and the different types of fats. Dr. Sarah Berry is one of the world's leading experts on human nutrition, who has personally run over 20 randomised clinical trials looking at how humans respond to different fats.

Our transformation into coach potatoes happened in the blink of an eye. Only 100 years ago, most people relied on manual work to make their living.  Today, things are different. Many of us live our lives in front of a screen. Online shopping and remote work mean some of us don’t need to leave the house at all. So how bad is this for us?  The answer is now clear: Low levels of physical activity lead to an increased risk of disease and a lower quality of life in older age. However, when we come to the question of what sort of exercise you should be doing, how often, and how much it contributes to weight loss, the answers might surprise you. In today’s episode, Jonathan speaks to a Human Physiologist to learn about the interactions between diet and exercise and their impact on human health: Dr. Javier Gonzalez is an associate professor of Human Physiology at the University of Bath and also a technical advisor to the athletes in the INEOS Tour de France cycling team.

There's a condition that leads to an increased risk of heart disease, dementia, and early death that's been affecting people for as long as they've existed. The many symptoms can severely impact quality of life - ranging from headaches and memory problems to anxiety and weight gain.  This condition affects more than half of the world's population, but unbelievably its rarely discussed and the scientific research that exists on it is limited.  It's called menopause, and it affects 1.2 billion women worldwide. It's not a disease, but the effects can be just as serious for some women. Jonathan talks to the British doctor who's working to educate us about menopause and bring the discussion on the topic into the mainstream. Dr Louise Newson is a GP, menopause specialist and founder of the Newson Health Menopause & Wellbeing Center. Director of the Balance Menopause App and the non-profit Newson Health Research and Education. Founder of The Menopause Charity.

For many of us, it's a ritual to help us wind down after a long day, an excuse to catch up with friends, or a lubricant to an awkward social situation. Alcohol can be delicious, but our relationship with it is often complicated.  Good times with friends aren’t without sacrifice, and many of us feel the morning after impact of a few too many drinks. For an unfortunate minority, alcohol can lead to addiction and even death.  What we want to know is, can alcohol ever be healthy? Is any amount of alcohol a sure path to an early grave, or could a glass of red wine be the best thing for your heart health? This episode examines these contradictions to see what the science says.  Jonathan speaks to two leading scientists to better understand the effects of alcohol: Tim Spector - scientific co-founder at Zoe and one of the top 100 most cited scientists in the world Dr. Sarah Berry - one of the world's leading experts in human nutrition, with over 30 randomised human clinical trials to her name Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00 - Intro 00:10 - Jonathan’s introduction 01:25 - Episode start 01:45 - Tim’s favourite alcohol 02:24 - Is red wine healthy? 04:56 - How does alcohol relate to our microbiomes? 08:41 - What’s the cause of alcohol's positive effects? 11:16 - The importance of the amount of alcohol consumed 15:47 - Understanding the adverse effects of alcohol 17:48 - Why do hangovers get worse with age? 21:41 - Does alcohol influence weight? 24:48 - Alcoholic beers vs non-alcoholic beers in relation to sugar 28:34 - Avoid alcohol if you have these conditions! 29:54 - How does fermentation of beer differ from kombucha? 32:21 - Organic and natural wine 35:10 - Summary 38:03 - Outro Follow Sarah: https://twitter.com/saraheeberry Follow Tim: https://twitter.com/timspector Follow ZOE on Instagram: https://www.instagram.com/zoe/ This podcast was produced by Fascinate Productions.

This plant has been used by human beings for thousands of years with samples found in 5000-year-old pottery discovered in the upper Amazon. The Mayans considered it a gift from the gods and used it in their sacred ceremonies, where it was believed to have mystical healing powers. For the Aztecs, it was worth more than gold and given to their victorious warriors.  We are talking, of course, about chocolate. Even though our relationship with chocolate spans thousands of years we still can’t agree about it. It seems obvious that something so delicious must be bad for us. Can there be any truth to the claims that chocolate can improve our mood, our health and even our libido?  Jonathan speaks to Professor Tim Spector, one of the world's top 100 most cited scientists and author of the diet myth, and Spencer Hyman, one of the world’s leading chocolate experts and founder of the craft chocolate business Cocoa Runners.  Download our FREE guide — Top 10 Tips to Live Healthier: https://zoe.com/freeguide Timecodes: 00:00 - Intro 00:10 - Jonathan’s introduction 01:19 - Lighting round questions, with true/false answers 05:49 - Why certain chocolates might be good 06:34 - What is fermentation?  09:54 - Which kinds of chocolates are good or bad for you? 12:14 - How to figure out the differences in chocolates  14:12 - Why is are chocolates classified the way they are 16:20 - Considerations about dark chocolate 20:38 - Personalized responses to chocolate 23:39 - On chocolate addiction 24:55 - How to taste chocolate 28:10 - Is smell an indicator as to what happens in our microbiomes? 31:52 - 3 things you should know when buying chocolate 33:17 - Description of chocolate in nature 37:15 - Sugar in chocolate 40:29 - Is fruit and nut milk chocolate healthier than dark chocolate? 41:27 - How much chocolate do you need for it to be beneficial? 42:59 - Should I watch out for lecithins in chocolate? 44:52 - Is eating half a bar of chocolate before bed a bad idea? 46:24 - Goodbyes & Outro Follow ZOE on Instagram: https://www.instagram.com/zoe/ This podcast was produced by Fascinate Productions.

1 in 5 people suffer from food intolerances, a figure that’s growing each year. As a result, people are eating increasingly restricted diets, removing dairy, gluten and many other foods from their plates. Unfortunately, they end up eating highly processed foods that damage their gut microbiome and lead to long-term health problems. Even with food restrictions, many people see limited improvements in their symptoms. The whole topic of intolerance is full of pseudoscience, dubious blood tests, and miracle cures. However, in the last few years, we have seen a revolution in our understanding, with gut bacteria now the stars of the show. This new understanding has profound implications for how we should treat our food intolerances.  Today we’ll focus on what the latest science says. Jonathan is joined by Will Bulsiewicz, board-certified gastroenterologist, New York Times best-selling author and ZOE's science board member, whose latest book is all about food intolerance.
