How To Actually Feed Your Gut Microbiome with Anu Simh

In this episode of The Mind–Gut Conversation, Dr. Emeran Mayer speaks with Anu Simh, a board-certified functional health coach, microbiome educator, and author of Flourish from Within: New Gut for Lifelong Health. Anu’s work centers on a question more and more people are asking: not just what to eat, but why certain ways of eating seem to support the gut in ways that ripple out to energy, metabolism, and long-term health.

The conversation explores the flourish diet, Anu’s framework built around microbial diversity, cultural adaptability, and practical strategies that work in people’s real lives. Drawing on her own journey from a gut health crisis to the research stacks at UCSD, Anu explains how traditional South Indian cuisine — rich in fiber, fermented foods, and polyphenol-dense herbs — was quietly aligned with emerging microbiome science long before the research caught up.

Together, they discuss why diversity matters more than any single superfood, how to distinguish beneficial complex carbohydrates from refined ones, the overlooked role of herbs and spices as sources of polyphenols, and how to retrain your palate to accept bitter and varied flavors. Anu also shares how she translates microbiome science into simple, repeatable eating patterns that don’t require hours in the kitchen or rigid meal plans.

This episode offers a thoughtful, evidence-based perspective on what it really means to feed your microbiome — and how to build sustainable habits that support gut health without overwhelming your life.
