Is your gut the missing key to longevity? In this episode, I sit down with Dr. Grace Liu to explore how your microbiome acts as a powerful “longevity organ” influencing your immune system, brain health, inflammation, and aging. We break down how modern lifestyles damage gut diversity—and what that means for your overall health.
We also dive into FMT, peptides and bioregulators, resistant starch, and the truth about probiotics and fiber. If you want simple, science-backed ways to rebuild your gut and improve your healthspan, this episode is packed with actionable insights.
