Tim Spector has spent much of his career studying the trillions of microbes that live on us and inside us. They outnumber our own cells 10-to-1. The microbes in our guts are essential to how we digest food, they control the calories we absorb, provide vital enzymes and vitamins and keep our immune system healthy.
He talks with Kathryn Ryan:
Dr Tim Spector is a professor of genetic epidemiology at Kings College in London. He runs the British Gut microbiome project, which aims to uncover the microbial content within the guts of British individuals to explain how lifestyle choices and diet influence the microbiome. He is also the founder and director of the TwinsUK Registry - and has written several science books, his latest being The Diet Myth, in which he argues that modern society and diets are destroying the good bacteria vital to our health.
