Dan Saladino discovers the world of the gut microbiota, the vast array of microbes within us all. From East Africa to the White House, it's a story that'll change the way you eat.
Dan is joined by Tim Spector, Professor of Genetic Epidemiology at King's College London, and author of The Diet Myth - The Real Science Behind What We Eat. Tim tells the story of how he became fascinated by the gut microbiome and our diet.
The programme also features a Dutch draper named Antonie van Leeuwenhoek, co-founder of the American Gut Project Jeff Leach, evolutionary biochemist Dr Nick Lane, and Alexandre Meybeck - a Senior Officer at the United Nations Food and Agriculture Organisation.
