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.

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?

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.

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.

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.
