The vagus nerve serves as the primary superhighway connecting the enteric nervous system directly with the brainstem. Targeted dietary interventions that reduce ultra-processed foods while introducing fermented foods foster microbial diversity that directly attenuates systemic neuroinflammation.

Key Summary Takeaways
SUMMARY
- Diets rich in diverse polyphenol antioxidants and prebiotic fibers increase short-chain fatty acid (SCFA) production.
- SCFAs cross the blood-brain barrier and support microglial homeostasis and synaptic plasticity.
- Simple dietary transitions towards Mediterranean-style whole food nutrition yield measurable mood and focus improvements in 6 weeks.
