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.

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?

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.

In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: If nuts are so full of fat, can they really be good for us?

There is no shortage of variety when it comes to the mighty (yet humble) nut and the ways we consume them. Dried, chopped, made into butter or roasted (over an open fire, anyone?) these little guys provide the nutrients our brains and bodies need in surprisingly high quantities. From industrially farmed to indigenously hand-harvested, the story of these nuts is, well…nuts!

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.

Eggs are nutrient-dense and have a long shelf life. Compared with many other protein sources, they’re on the cheaper side. But they’re not as popular as they used to be. And a lot of this comes down to a debate about cholesterol.

In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: What’s the truth about eggs?

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.

• A redefinition of constipation by King’s College London, published in the American Journal of Gastroenterology (2019) here

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.
• Tim Spector is a co-founder of ZOE and one of the world's top 100 most cited scientists.

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.

More than half of us have high cholesterol — and new research suggests that having even slightly raised levels in our 30s could significantly increase our chances of developing heart disease.

Medication is a common fix, but it comes with side effects. So, today we’re looking at how much changing our diets can help.

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.

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.

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.

So, if acid escapes from your stomach and reaches your esophagus, it can cause a painful sensation in the chest — this is heartburn. It isn’t rare, with more than 1 billion people suffering from it globally.

Good information about vitamins is hard to find. With over 70% of Americans and 40% of Brits using them, it's a hugely lucrative market, which means numerous voices in the media and online pusing a pro-vitamin agenda. All without the scientific evidence to support their claims. 

So do we need vitamins to lead a healthy life? Or could these supplements actually cause serious health complications?

In this episode, Jonathan speaks with Prof. JoAnn Manson and Dr. Sarah Berry to better understand how vitamin supplements affect our health.

• JoAnn Manson is a professor of epidemiology at the Harvard School of Public Health and one of the world's most cited researchers. She’s run multiple enormous studies with over 20,000 participants to uncover the real effects of vitamin supplementation on our health.

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. In this episode, we learn more about his fascinating research, how microbes may affect our brain, and to eat to appease your gut bugs.

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.

Have you ever lost your temper because you were hungry? Feeling short-tempered when you’re overdue a bite to eat is an almost universal experience, with its own adjective - ‘hangry’. If missing just one meal turns you into a grump, you may think that fasting would turn you into the Incredible Hulk. However, new data suggests this might not be the case. 

In this daily episode of ZOE Science & Nutrition, Dr Sarah Berry joins Jonathan to answer the question: how does fasting affect your energy and mood?

This episode is part of a limited series to celebrate the launch of The Big IF Study: The world’s largest clinical study to discover how intermittent fasting affects our mood, energy and hunger levels. Want to know if intermittent fasting can work for you?

Can you make it from lunch to dinner without a snack? Tradition tells us that three meals a day is the right way to eat, but times have changed, and many of us now choose to eat little and often. The debate continues as to which is better. 

Today, we discuss new data that could settle this once and for all.

In this daily episode of ZOE Science & Nutrition, Jonathan is joined by Dr Sarah Berry to answer the question: should we eat little and often or 3 meals a day?

Nowadays, food can be delivered to your door with just a few swipes of your smartphone. The result? Many of us eat more frequently, at any time of the day. And this may have some downsides. New research shows that for our gut bacteria to perform their helpful activities, we may have to embrace the dietary patterns of our ancestors. 

In today’s daily episode of ZOE Science & Nutrition, Jonathan is joined by Tim Spector to answer the question: How do gut bacteria repair your gut while fasting?

We’ve all been there at least once, hovering by the fridge and looking for something to graze on just before bed. What you eat after dark can disrupt your sleep and digestion. Yet new evidence suggests that when we snack is less important than what we snack on, so suddenly that midnight snack may not be a guilty pleasure after all.

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?

Where were you in 2015? President Obama was in the White House, The UK was a member of the European Union, and you couldn’t escape Bruno Mars's global smash: Uptown Funk. More importantly, 2015 marked the release of Tim Spector’s first book: The Diet Myth.

If you think the world has felt different since 2015, wait until you hear about the advances in nutritional science. Since then, Tim has had a chance to rethink his position on dietary staples like bread, milk, ultra-processed foods and more. 

He’s put everything he’s learnt into his new book Food for Life: The New Science of Eating Well. 

In this episode, Tim speaks with Jonathan about what he got right, where he went wrong, and what the future holds for the world of nutrition.

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.

Diets rich in fiber are associated with good heart health and metabolic wellbeing. This type of diet can do wonders for our gut microbiome.

With so many benefits, relatively low cost, and high availability, fiber should be a staple nutrient in our diets — but most of us have a deficiency.

In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: If fiber is so good for us, why are we not eating enough of it?

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.

Most of us are familiar with the unpleasant feeling of being bloated. It can happen after eating specific foods or when you experience slower bowel movements. Sometimes, it can be a symptom of an underlying health condition. 

To take a closer look at issues related to gas and bloating, we’ve invited a special guest this week: superstar gastroenterologist and Zoe’s US Medical Director Will Bulsiewicz.

In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: what are the main causes of gas bloating and how do we stop it?

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. She is on the vanguard of a new field, and her research carefully measures the exact effects of the foods we eat on climate change.

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. He’s a world leader in the field and the author of Lifetime: the new science of the body clock.

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.

Biochemist Jessie Inchauspe heads into work one morning at a genetics lab in California. During the morning meeting, management offer staff the chance to self-test a new medical device. Jessie accepts. 

She couldn’t have known this device would take her on a journey of discovery to reshape her health and help countless others do the same.  

The device was a continuous blood sugar monitor, and it was this, combined with her academic background, and a remarkable willingness to use herself as a lab rat, that began a journey of discovery into how blood sugar affects our health. 

In today’s episode, Jonathan is joined by two leading experts on the topic:

• Jessie Inchauspe is a biochemist, bestselling author, and founder of the Glucose Goddess movement who’s helped hundreds of thousands of people improve their health by making cutting-edge science accessible.
• 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.

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?

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? Or is this just another marketing ploy?

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 an author, founder of the sourdough school, and a specialist in bread nutrition and digestibility.
• 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

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?

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 to 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.
