Fermented Foods, Fibre, and Immunity | Justin Sonnenburg, PhD, and Christopher Gardner, PhD

In Episode #191, I sat down with Stanford University Professors Dr Christopher Gardner and Dr Justin Sonnenburg to talk about fermented foods, fibre, gut health, and immunity. This conversation was organised following the results of their latest randomised controlled trial, ‘gut-microbiota-targeted diets modulate human immune status’, which was published in Cell Press in 2021. Listen to this episode to find out about what defines a healthy microbiome, what we can learn from studying the microbiomes of traditional populations such as the Hadza tribe, and so much more. Justin and Christopher also share the mission behind their study of fibre and fermented foods, what they found (including their findings regarding fibre intake and the effectiveness of probiotics), and the key takeaways.
