Alanna Collen Wrote "10% Human" in 2015 and it sent shockwaves across the globe.

Her path of discovery and personal healing came after a devastating reaction from a cycle of antibiotics - ultimately leading her to discover the strange world of microbes and our relationship with them.

In this episode we cover:

• Microbes have been evolving with us since before we were human

• 10% human refers to the statistic that there are 10x more microbes in and on the body that human cells. That number has shifted closer to 50% recently, but it says a lot about our relationship to microbes

• Skepticism of the assumption that diversity of microbiome in the gut is the answer for optimal health (some developing nations eat 1 thing Inuit)

• Koala moms feed their joey's poop because eucalyptus is hard to digest

• Tips for keeping a healthy microbe balance in and on your body. Like - not using antibacterial soap for body or home. The importance of vaginal bacteria in birth and the problems with C-sections and more.

• Her new book Fatology - the role of microbes in obesity
