ZOE Science & Nutrition

If you had to do just one thing to improve your health, what would it be?Our busy lives mean it can be difficult to keep up healthy habits, and with so much conflicting advice out there it’s tricky to separate fact from fiction. In today’s episode, Jonathan is joined by medical doctor, journalist, and presenter Michael Mosley, who is alongside ZOE regular Tim Spector, to discuss Michael’s four key habits to improve our health. Michael’s latest book ‘Just One Thing’ explores these habits and has seen him speak to singing scientists and eccentric iceman to healthy habit experts and evangelists. And of course, being Michael, he tried every habit out himself. We talk about which methods are the most effective, which he has incorporated into his life, and how he makes his new habits stick.Take part in the Big Poo Review 💩.

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) hereThe State Of The Nation’s Gut, Love Your Gut hereEpidemiology of constipation in Europe and Oceania: a systematic review from Prichard & Bharucha via BMC Gastroenterol hereRecent advances in understanding and managing chronic constipation from Peppas, Alexiou, Mourtzoukou & Falagas via F1000Research hereIf you want to uncover the right foods for your body, head to joinzoe.com/podcast and get 10% off your personalized nutrition program.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.

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?

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.

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.

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.

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.

It isn’t rare, with more than 1 billion people suffering from it globally. In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: Why do we get heartburn, and what’s the best way to deal with it?Follow ZOE on Instagram: https://www.instagram.com/zoe/If you want to discover the right foods for your body, head to joinzoe.com/podcast and get 10% off your personalized nutrition program.Studies referenced in the episode:‘Prevalence and clinical spectrum of gastroesophageal reflux: a population-based study in Olmsted County, Minnesota’ from Gastroenterology here‘Proton-pump inhibitors and risk of fractures: an update meta-analysis’ from Osteoporos Int. here‘Proton pump inhibitors alter the composition of the gut microbiota’ from BMJ  hereThis podcast was produced by Fascinate Productions.
