Episode notes
Impact of Industrialization on Microbiome
- Modern industrialization and lifestyle drastically reduce gut microbial diversity, affecting immune and metabolic health.
- Traditional non-industrial populations have more diverse microbiomes and fewer chronic diseases linked to better lifestyle factors.
Microbial Diversity Loss
- We've lost about half of our ancestral gut microbial diversity, and this loss accumulates across generations.
- Microbes adapt rapidly, making the concept of microbiome mismatch complex.
Benefits of a Wilder Microbiome
- Introducing a wild microbiota to lab mice improved survival and disease resistance.
- Animal models suggest a "wilder" microbiome promotes host health and resilience.
