Thirty plants this week, think you could do it? It might sound a lot, but it’s easier than you think. Fruit, veg, nuts, seeds, even coffee all count as plants.
Legendary chef Hugh Fearnley-Whittingstall joins us to share tips on eating more plants. Hugh’s new book ‘How to Eat 30 Plants a Week’ explores the wild world of legumes, grains, herbs and beyond. He explains that getting your thirty plants each week can be simple, fun and delicious.
Joining Hugh is Tim Spector - professor of genetic epidemiology at King’s College London and ZOE’s scientific co-founder. Tim explains why our gut microbiome loves plants, highlighting the importance of polyphenols, healthy fats and fiber.
You’ll finish this episode inspired, empowered and likely... hungry.

Allergies are on the rise in both infants and adults. Many are calling it an epidemic. Allergies can limit your diet, cause irritation, and in some cases be life threatening.
In today’s episode, we discuss the evidence suggesting that our gut plays a key role in protecting us from food allergies.
Professor Gideon Lack tells us how we can reduce the risk of allergies developing in children. Gideon also shares innovative ways to treat allergies and significantly reduce the risk of death.
Gideon is Professor of Paediatric Allergy at King’s College London. His groundbreaking studies into allergies have reversed the official medical advice of multiple countries.

What do astronauts and cancer patients have in common?
Jonathan explores this fascinating connection with Dr. Jessica Scott, learning how six decades of NASA research is being used to help the recovery of cancer survivors. New research challenges the traditional notion that you should rest during cancer treatment. Instead, Jessica’s studies into exercise could hold the key to a long and healthy life post-diagnosis.
Dr Jessica Scott started her career at NASA where she spent 7 years designing exercise programs for astronauts in outer space. Now, as the principal investigator at the world-leading Memorial Sloan Kettering Cancer Center, she is using her unique skillset in the fight against cancer.

Our modern lifestyles mean that most of us don’t live our lives in sync with our circadian rhythms, which puts our health and well-being at risk. Eating and sleeping at the right time are important tools to help us align our circadian rhythms and reduce our risk of chronic disease.
In this episode, circadian rhythm expert Prof. Satchin Panda will tell us how light and food act as master regulators of our body clock, how aligning our lifestyles with our body clock can improve our health, mood and energy levels and how to do this in practice.
Satchin is a world-leading expert in the field of circadian rhythm research. He’s associate professor at the prestigious SALK institute, he’s recipient of the Dana Foundation Award in brain and immune system imaging and he’s also the author of two best-selling books, The Circadian Code and The Circadian Diabetes Code.

After the tragic news of Michael Mosley's passing, we are re-releasing our episode with him, originally released in March 2023:
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.

very important information ,thanks ZOE 🌺🌼💖
The carnivore diet, heralded as a panacea by some, faces scrutiny as its proponents claim miraculous health benefits while skeptics question its sustainability and potential risks. Advocates argue for its simplicity and purported improvement in autoimmune conditions and weight loss. However, critics cite concerns about nutritional deficiencies, lack of fiber, and long-term health consequences such as heart disease and cancer. Amidst the debate, sites like https://www.flexmagichealth.com/ provide platforms for both sides to present their arguments, offering research-backed insights and personal anecdotes. As discussions persist, the carnivore diet remains exposed to ongoing examination, revealing both its promises and pitfalls.
Don't make it too complicated. The key is you need to go low carb, once you eat low carb and stop snacking, you'll naturally intermittent fast. Just follow your feelings. Easy.

surprised you didn't do more research before recording this. you don't know what you're talking about at all. I'm not even advocating carnivore but this was hardly a refutation.
Your insights have been incredibly helpful. Thank you for sharing! https://www.chemicalbull.com/products/2-isopropyl-4-methyl-thiazole
it would have been interesting to consider transplant recipients who have to take powerful immunosuppressants to prevent rejection. so due to a (necessary) medical intervention rather than inflammation. Emphatic dietary advice firmly discourages fermented foods. any comment in the light of this fascinating podcast
why would eating meat which was a major component that the human species evolved on be bad for us? doesn't make sense! I'd give the ultra processed seed spreads a miss too rather than reducing butter. not good information given here.
