Artificial sweeteners - worse than sugar?

Artificial sweeteners - worse than sugar?

Artificial sweeteners are everywhere. Not only in diet soft drinks but in many foods that you wouldn’t expect. You’ve probably eaten some today without realising. Sweeteners have been around for over a hundred years yet remain the subject of much debate. It's hard to know how they stack up next to the alternatives. In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: are artificial sweeteners worse than sugar?

Can spices improve your health?

Can spices improve your health?

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. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.

How healthy are meat and dairy alternatives?

How healthy are meat and dairy alternatives?

Vegan diets are increasingly popular. As more of us reduce our animal product consumption, countless new meat and dairy alternatives appear on our supermarket shelves. Manufacturers market these products as healthy options (unsurprisingly), but perhaps we shouldn’t be so quick to trust them…  In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: are meat and dairy alternatives healthier than their animal-based counterparts?

How food can improve your mood

How food can improve your mood

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.

Can you reverse damage from a bad diet?

Can you reverse damage from a bad diet?

A recent study claims that eating a hotdog reduces life expectancy by 38 minutes, and eating salmon could extend it by 70 minutes. At face value, this data implies you can eat your way to immortality. Taken with a pinch of salt, it suggests you can offset the harm from poor dietary choices. But does food really work this way?

This is what the Keto Diet does to your body...

This is what the Keto Diet does to your body...

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.

Processed foods - convenient or catastrophic?

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.

Inflammation, aging and disease. What's food got to do with it?

Inflammation, aging and disease. What's food got to do with it?

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.

Can bread be healthy?

Can bread be healthy?

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.

Is Coffee Healthy?

Is Coffee Healthy?

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.

Your Gut is Full of Bugs: Why This is Great News

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.

Fats and oils: What’s the real story?

Fats and oils: What’s the real story?

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.

Is exercise or nutrition more important for weight loss?

Is exercise or nutrition more important for weight loss?

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.

Menopause: How your body changes and what you can do

Menopause: How your body changes and what you can do

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.

Alcohol: Can it ever be healthy?

Alcohol: Can it ever be healthy?

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.

Is Dark Chocolate Good for Weight Loss?

Is Dark Chocolate Good for Weight Loss?

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.

Food Intolerances: What's the Story?

Food Intolerances: What's the Story?

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.
