Episode notes
Animals Eat Feces To Boost Microbes
- Dogs eating other animals' feces likely seek microbial diversity and immune benefits, not just gross behaviour.
- Felice Jacka uses animal coprophagy as an example of microbial transfer in nature.
Many Diseases Link To Microbial Changes
- The microbiome associates with many conditions—IBD, IBS, cancer, metabolic diseases—but causality is often unclear.
- Paul Griffin stresses we must distinguish correlation from causation with further studies.
Diet Alters Microbiome Fast
- Diet can change the gut microbiome rapidly; measurable shifts occur within 24 hours and profound changes within two weeks.
- Felice Jacka cites intervention studies showing diet-driven microbial shifts.
