Episode 028 - Dr Alan Walker

 

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 Alan Walker shares his insights on the microbiome field in this episode. The conversation covers topics such as the development of the field, new technologies, and debates about the benefits and misconceptions of microbiome-modulating therapy. Technical topics such as microbiome sequencing, next-generation probiotics, and fecal microbiota transplantation are also discussed. The conversation is dynamic and includes friendly debates between friends. The episode is recommended for those interested in learning more about the microbiome.

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, 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.
