S2 EPISODE 29 - The Microbiome, Gut-Brain Axis & How To Build A Healthy Gut w/ Miguel Mateas PhD(c)

In season 2 Episode 29, Dr. Bubbs interviews Miguel Mateas PhD(c) to talk about the gut microbiome and the implications on the gut-brain axis. In this episode, Miguel discusses the dynamic ecosystem that makes up the gut, how specific bacteria are attracted to certain conditions and the impact of processed food on the gut microbiota, as well as how exercise impacts gut microbial diversity (including new research on how the mindset may play a role), and then dives into the many ways the gut microbiota communicates with the brain and implications for health and performance. Great insights and metaphors to explain complex topics from Miguel!

Lay-Ups In This Episode

1)    Dysbiosis is an imbalance between the “good” and “bad” bacteria of the gut.

2)    The gut communicates to the brain via the vagus nerve, tryptophan, butyrate and many other signals from the digestive system.

3)    Gut diversity is the most reliable biomarker for health.
