Spilling Our Guts: Decreased Diversity in the Human Microbiome

17:17 minutes

Diversity is the key to happiness…when it comes to your microbiome. Gut bacteria diversity varies in each species and can be influenced by different settings, and not always for the better. Surgeon John Alverdy discusses how a stay in the hospital can affect your microbiome, and Andrew Moeller explains how the evolution from apes to humans may have caused us to lose a few gut bacteria along the way.
