1 in 3 people have anxiety. It’s the most common mental health disorder in the world. And many of us know what anxiety feels like: palms sweating before a job interview, losing your appetite before a looming deadline, a pit in your stomach when you get bad news. It’s not just in your head, it’s in your gut. Today, we’ll learn how food could help us cope. Our guest explains the rising global trend toward increased anxiety: its rise through the pandemic, and explosion among young people.  Dr. Uma Naidoo is on the forefront of nutritional psychiatry. She directs the first hospital-based Nutritional Psychiatry Service in the US, at Massachusetts General Hospital and teaches at Harvard Medical School. Uma will help you understand the symptoms and biology of anxiety, painting a picture of the risks it poses for long-term health. And her diet tips will help you fuel your gut for a healthy mind. 🥑 Make smarter food choices.

It’s safe to say she knows a thing or two about heart health and cholesterol. 🥑 Make smarter food choices.

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.

Did you know you can now buy ice cream with added protein? Even breakfast cereals are jumping on the trend, boasting an extra protein punch. In nearly every supermarket aisle, you'll spot the catchy slogan "high in protein" plastered across packaging. But why is that? Are we not getting enough protein already, or are these high-protein products giving us too much? Our guest is Christopher Gardner, a professor at Stanford University and a member of ZOE’s scientific advisory board, who has published widely on the relationship between protein and our health.  🥑 Make smarter food choices.

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. We'll also tackle the age-old question: do we really need Vitamin C supplements? 🥑 Make smarter food choices.

As adults, food shopping can be a minefield. But when it comes to feeding your kids, the stakes are even higher. Our food environment is rife with misinformation. Brightly coloured labels on packaged, often ultra-processed foods promise high protein, high fibre and low calories.

Today, we hear from two of the UK’s most-trusted nutritionists (and both parents of small children) on how to keep your kids eating well.  Rhiannon Lambert has authored four books, including recent Sunday Times bestseller The Science of Plant-Based Nutrition. Half a million people follow her for nutrition advice on Instagram. ZOE’s Head Nutritionist, Imperial College London lecturer and bestselling author of Every Body Should Know This, Dr. Federica Amati, joins Rhiannon for today’s conversation. 🥑 Make smarter food choices.
