South African scientist Tim Noakes has a new book out, ‘Lore of Nutrition’, and is armed with more expertise to help answer your nutrition and food questions. He sits down with Gareth to discuss how one can live their healthiest life beginning with analysing our obsession with body fat, muscle mass and vaccination in children, amongst other things. He speaks out on why he believes medicine has become a business and no longer just a profession, as well as how he deals with the criticism he receives.
