How Does Gut Diversity Impact Your Mental Performance?
Hosts Emma Sullivan and David Park explore the gut-brain axis and explain why microbial diversity—not just the presence of "good bacteria"—directly influences your focus, mood, and mental performance. They break down the science behind how 90 percent of your serotonin is produced in your gut, then cut through supplement marketing to share what actually works: eating 30 different plant foods weekly and adding fermented foods, both of which produce measurable changes in microbiome diversity within weeks. The episode closes with practical, additive strategies for busy people—no meal prep required—and addresses how stress and sleep disrupt the microbiome in real time.Follow The Wellness Rhythm Show: ▶️ YouTube: https://www.youtube.com/@TheWellnessRhythmShow 📖 Newsletter: https://thewellnessrhythmshow.substack.com Powered by VoxCrea.AI
