REPLAY: Focus on Fibre: Fuelling the Microbiome with Dr Will Bulsiewicz

Gastroenterologist Dr Will Bulseiwicz and our ambassador Emma Sutherland explore holistic methods of supporting a gut microbiome that reduces risk of developing chronic disease. Will takes into consideration that we’re uniquely bio-individual to the level of our gut microbiome and a person’s health is intrinsically connected to its own unique gut terrain a.k.a. gut microbiome. Emma and Will also discuss the benefits of maintaining a healthy gut lining by supporting mucus secretions such as secretory IgA, and the usefulness of probiotics. They also discuss the various natural sources of probiotics beyond pills and powders, and how to use them effectively in a clinical setting.
