"We've grown up and taken our health class in school and learned all the parts of our body. But then to think that's only half the story. That actually, at least half the cells are bacterial and not human at all, and they're invisible. That's something big to get your head around."

On today's episode, Kristina sheds some light on what terms like microbiome and micriobiota actually are. Kristina and Konner discuss changing our ideas and paradigms about germs and bacteria. Not only that, Kristina lays out the incredible width of things that our microbiome can affect, ranging from overall mortality, to even the makeup of our brains.

Lastly, and thankfully for everyone's sake, Kristina talks about things we can all do to assist our own microbiome, what is fact, what is fiction and how to avoid some of the people and products out there that are based on nonsense.
