In this episode of the Vegans Explore Podcast, we sit down with Dr. Will Bulsiewicz, also known as Dr. B, for a powerful conversation on fiber, microbiomes, and the future of human health.

Dr. B breaks down why the gut microbiome is being recognized as a newly defined organ, how fiber fuels healing throughout the body, and why eating a wide variety of plants matters more than dietary perfection. We explore the science behind inflammation, immunity, metabolism, and emerging cancer research, all explained in a way that’s accessible for Vegans, pre-Vegans, flexitarians, and the simply curious.

The conversation also delves into Dr. B’s latest book, The Fiber-Fueled Cookbook, and his philosophy of food as a toolkit for long-term health rather than a set of rigid rules. From fermented foods to everyday plant-forward choices, this episode offers practical insights you can start using right away.

If you’re interested in gut health, plant-based nutrition, and evidence-based wellness without pressure or labels, this episode is for you.
