The Microbiome Diet Reset
by Mary Purdy, MS, RDN

What do the microbes in your gut have in common with the microbes in healthy soil?
More than you might think.
The Microbiome Diet Reset explores the fascinating world of the trillions of microorganisms that live within us and influence everything from digestion and immunity to mood, metabolism, and overall health. Through practical nutrition guidance, simple recipes, and a healthy dose of humor, this book helps readers cultivate a thriving gut microbiome and a deeper understanding of how food shapes well-being.
But the story doesn’t stop with the microbes inside us.
Emerging research continues to reveal important connections between soil health, plant health, food quality, and the human microbiome. The same diverse microbial communities that help build healthy soils also support resilient ecosystems and nutritious foods. In many ways, our health is intertwined with the health of the natural systems that produce our food.
Inside you’ll find:
- Easy-to-understand explanations of the gut microbiome and its role in health
- Practical diet and lifestyle recommendations to support digestive and immune function
- Delicious recipes featuring vegetables, legumes, whole grains, fermented foods, herbs, and other microbiome-friendly ingredients
- Guidance on minimizing common dietary and lifestyle factors that may disrupt gut health
- Science-backed information presented in an accessible and engaging way
From tangy Kimchi to hearty Four Bean Chili, this book offers simple, affordable ways to bring more microbiome-supporting foods to your table while making healthy eating enjoyable and realistic.
And. GREAT news! Many of the foods that nourish a healthy gut microbiome: beans, vegetables, fruits, whole grains, nuts, seeds, and fermented foods, also happen to align with dietary patterns that support environmental sustainability and planetary health. By embracing a more diverse, plant-rich way of eating, we can support not only our own well-being, but also healthier food systems and a healthier planet.
It’s a lighthearted approach to a complex and rapidly evolving field, designed to empower readers to make meaningful changes that benefit both people and planet.
Because when we care for the microbes, they tend to take very good care of us.
