15 snips
Mar 11, 2025 Dr. Anissa Armet, a registered dietitian and postdoctoral researcher at the University of Alberta, dives into how industrialization has impacted our gut microbiome. She discusses her groundbreaking research on restoring microbial diversity through a 'Restore Diet,' focusing on the reintroduction of the microbe L. reuteri. Challenges in microbiome research, the significance of dietary fiber, and the connections between gut health and inflammation are thoroughly explored. Listeners will gain insights into dietary interventions that could enhance overall well-being.

Episode notes
Personal Journey to Microbiome Research
- Dr. Anissa Armet's interest in nutrition stemmed from her ulcerative colitis diagnosis.
- This led her to explore diet's impact on health and eventually the gut microbiome.
Defining Gut Microbiome Restoration
- Gut microbiome restoration compares modern microbiomes to those of non-industrialized populations or ancestral samples.
- These comparisons highlight changes due to lifestyle and diet, especially decreased fiber intake.
Challenges in Microbiome Research
- Defining a "healthy" microbiome is challenging due to individual variation and adaptation to environment.
- Comparing industrialized and non-industrialized microbiomes helps determine potential health implications.
