Episode notes
Gut Microbiome Drives Digestive Issues
- The rise in digestive issues globally is linked to lifestyle changes spanning generations, not just one cause.
- The gut microbiome, heavily influenced by food, is fundamental to these health problems.
Gut Health Beyond Microbes
- Gut health encompasses digestion, motility, gut lining health, and microbiome diversity.
- Our gut microbes outnumber human cells and influence digestion, immunity, metabolism, mood, and gene expression.
Add Variety to Heal Gut
- Avoid permanently restricting your diet; instead, gradually add variety to improve gut microbial diversity and health.
- Like physical therapy, build gut tolerance progressively rather than eliminating foods long-term.
