Tim Spector — a Professor of Genetic Epidemiology and microbiome researcher — spent three days eating like a hunter-gatherer with the Hadza in Tanzania and dramatically changed the diversity of his gut microbiome. He wrote about his experience in a recent article for CNN, and we brought him on ReWild Yourself Podcast to share his story and explain the importance of gut diversity for robust health.

Tim is also the Founder and Director of the TwinsUK Registry at Kings College, London — the richest collection of genotypic and phenotypic information worldwide — and has recently been elected to the prestigious Fellowship of the Academy of Medical Sciences. He has published over 800 research articles and is ranked as being in the top 1% of the world’s most cited scientists by Thomson-Reuters. He held a prestigious European Research Council senior investigator award in epigenetics and is a NIHR Senior Investigator. His current work focuses on omics and the microbiome, and he directs the crowdfunded British Gut microbiome project. He is a prolific writer with several popular science books and a regular blog, focusing on genetics, epigenetics and most recently, microbiome and diet.

In this interview, Tim brings us up to speed on our current scientific understanding of the microbiome, what his research has uncovered and how we can apply this knowledge to our own diet and lifestyle to achieve a healthy microbiome. Ultimately, Tim has found that the key to a diverse and healthy gut is to ReWild Yourself — eating a species-rich diet of foraged foods and interacting with the natural world (translation: exposure to plentiful and diverse microbes). Tune into our conversation for an in-depth outline of the trillions of bacteria that inhabit your human animal, and learn how you can cultivate a healthy, robust community of beneficial gut bacteria.
