The following is a conversation with Dr. Alan Walker, a senior lecturer at the Rowett Institute for Nutrition and Health at the University of Aberdeen.
Dr Walker has worked in the microbiome field for the last 20 years. Throughout this episode, he shared with us some of his insights into how the field has developed, and how new technologies have improved our understanding of the microbiome. We also spent a lot of time Having some fun debates about the pros and cons, some of the benefits associated with microbiome modulating therapy, and where some myths and misconceptions lie.
For the generalist who wants to learn more about the microbiome, I think this is an excellent episode. We also get pretty deep and pretty technical in some areas, like, for example, microbiome sequencing, next-generation probiotics, and whether the microbiome causes obesity or contributes to obesity. There are tons in here and we go right the way across the microbiome field talking about diagnostics, at-home microbiome testing, the use of faecal microbiota transplantation, and what is a healthy microbiome.
I wanted to take this opportunity to thank all of the listeners and supporters of the podcast for everything you've done to help us build the name, and the brand, and to get the message out there around microbiome being critically important and gut health being really important for wider body health.
