Story summary
- The gut microbiome hosts up to 100 trillion microbes and significantly influences mood, immunity, and energy balance.
- It produces about 90% of the body's serotonin and coordinates 70% of immune responses through IgA antibodies.
- A balanced microbiome generates short-chain fatty acids that support gut barrier integrity and prevent chronic inflammation.
- Dysbiosis disrupts these functions and can lead to energy depletion and mood disturbances, and consuming a fiber-rich diet supports diversity.
