In this episode of the Vegans Explore Podcast, we’re joined by Dr. Will “Dr. B” Bulsiewicz, New York Times bestselling author and leading voice in gut health science, for a deep and accessible conversation on fiber, microbiomes, and the future of human health.

Dr. B breaks down why the gut microbiome functions like a newly discovered organ, how fiber fuels healing throughout the entire body, and why diversity of plants matters more than perfection. We explore the science behind inflammation, immunity, metabolism, and even cancer outcomes, while keeping the conversation inclusive for Vegans, pre-Vegans, flexitarians, and anyone curious about eating more plants.

This episode also dives into Dr. B’s latest project, The Fiber-Fueled Cookbook, and why he views food as a toolkit for long-term health rather than a rigid set of rules. From fermented foods to everyday plant choices, this conversation offers practical insights you can apply immediately.

Listen in to understand how small shifts toward fiber-rich, plant-forward eating can unlock powerful health benefits and why the future of medicine starts in the gut.
