Our Editor's Take

Every day, people receive new and sometimes conflicting information about their bodies, minds, and world. The ZOE Science & Nutrition podcast exists to help sort through the noise. ZOE is a company that helps people understand their unique dietary needs.

Host Jonathan Wolf interviews a renowned doctor, nutritionist, or scientist each week. They discuss health-related topics, answer listener questions, and give practical advice. The purpose is not just to simplify scientific papers. The show wants to make this information accessible for the average person. Wolf believes that what's in these papers shouldn't be a secret. So the ZOE Science & Nutrition podcast is here to enlighten the public.

This podcast also discusses the impacts of nutrition on mood, mental health, and the planet. It serves as a reminder that food and drink do more than satiate hunger and thirst. What people choose to eat impacts the world and how people experience it.

ZOE Science & Nutrition also talks about other health-related topics. Is hormone replacement therapy safe? What are the secrets to good sleep? What are good habits to develop? Wolf and guests like Tim Spector and Eric Topol answer these questions and more.

It can be challenging to navigate health information. The world is saturated with pseudoscience. In this podcast, Wolf gives listeners evidence-based information. The host also issues advice to help them see fact from fiction. The science speaks for itself, but Wolf is giving it a platform. The ZOE Science & Nutrition podcast is here to guide people in the right direction.

In this episode, Dr. Suzanne Devkota, Director of the Microbiome Research Institute at Cedars-Sinai, shares groundbreaking findings on how gut bacteria interact with belly fat. Tim Spector, professor of epidemiology and scientific co-founder at ZOE, also joins the conversation to explain how the diversity of your gut bacteria affects weight and overall health.

Are artificial sweeteners harming your gut? | Dr. Eran Elinav and Prof. Tim Spector

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

The truth about expiry dates, freezing food and vegetable scraps | Carleigh Bodrug and Dr. Will Bulsiewicz
We waste a shocking 40% of the food we buy. We throw away foods like carrot tops, beet greens, and spent coffee grounds. These ‘food scraps’ stuff our landfills and drain our pockets. But we can eat these foods and many of them offer tons of healthy nutrients. Today’s guest is Carleigh Bodrug. Carleigh’s published a best-selling cookbook with over 140 recipes made from food scraps you might otherwise throw away. Her mission is simple: eat more plants. Her online community, PlantYou, has more than 10 million followers. She’s joined by Dr. Will Bulsiewicz. Will is a board-certified gastroenterologist and ZOE’s U.S. Medical Director. He reveals the hidden nutritional value of these food scraps, and how ‘scrappy cooking’ can get you eating that all-important 30 plants per week.

Eat your way to better gynecological health | Dr. Jennifer Ashton & Prof. Sarah Berry
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.

4 immunity tips for healthy ageing | Dr. Jenna Macciochi
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. Instead, it should be balanced. In this episode, Jenna - a Senior Lecturer in Immunology at the University of Sussex - reveals how your immune system is your body’s housekeeper. 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.
