A cool new piece of research has come out looking at the gut microbiome, bacteria, what happens when people eat different diets, and what this means for that claims that are made around what is the optimal human diet, and how the gut feeds into that conversation. We ensure we make this show practical, but also get to the heart of what the science is trying to tell us. Enjoy. A link to the research paper: https://journals.asm.org/doi/10.1128/mBio.00579-21
