Introducing 4 immunity tips for healthy ageing | Dr. Jenna Macciochi from ZOE Science & Nutrition. Follow the show: ZOE Science & Nutrition 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.
