Best of: Making sense of the gut biome

The holidays are here, and with that many of us are preparing to enjoy meals with family and friends. One of my previous guests on the show, Professor Michael Fischbach, tells us that the “gut biome” – that is, the complex community of bacteria that lives in our gastrointestinal tract – is what makes digesting and extracting nutrients from those meals possible. It’s a fascinating conversation about the important role bacteria plays in the human digestive system. I hope you’ll tune in.
