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.

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.
