“We are, by definition, an ecosystem. The microbiome reveals a more connected biology, radically transforming our approach to medicine, hygiene, diet, and living.”

Ara Katz & Raja Dhir

Our bodies are comprised of about ten trillion cells. But our microbiome — all the bacteria, viruses, and fungi that live in or on our bodies – outnumber human cells by a factor of 10.

Indeed, we are far more microorganism than human.

Moreover, rapidly developing science reveals the vast extent to which the nature of our personal microbiome drives not only our propensity for disease and digestive health, but also, quite surprisingly, can dictate our mental disposition, cognitive function, and even our specific food cravings.

Today we take a magnifying glass to the mind-blowing netherworld of microbiota to illuminate their implications not just on human health, but the well-being of planet Earth at large.

Our stewards for this fantastic voyage are Ara Katz and Raja Dhir, the co-founders of Seed, a venture backed microbiome company at the pioneering edge of bacteria science.

Ara is a serial entrepreneur and fellow at the MIT Media Lab’s Center for Future Storytelling and CCA’s DesignMBA program. She was named one of the “50 Most Influential Women in America” by Marie Claire, listed on Business Insider’s “Silicon Alley Top 100” and “36 Rockstar Women in NYC Tech”, and was recently included in Create + Cultivate’s 100 List for STEM.

One of the most knowledgeable people I have ever met when it comes to our rapidly evolving understanding of the microbiome, Raja is a life sciences entrepreneur and a member of the Microbiome Think Tank at Mass General Hospital. He sits on the editorial board for the scientific journal Microbiome as well as the advisory committee for the International Scientific Association for Probiotics and Prebiotics. In addition, he is a director and co-chair of the scientific advisory board for Micropia, a $20MM microbial ecology and education platform as well as the world’s first museum dedicated to microbes.

Today we cover it all.

First, we define the microbiome. We discuss the difference between prebiotics and probiotics. And to cut through the consumer confusion fomented by gut health commodification, we separate fact from fiction by examining the difference between an effective priobiotic and the countless food and supplement products simply marketed as such.

Most importantly, we explore what the latest science tells us about the power of microbes to heal our bodies, positively impact childhood development, reinvigorate the quality of our soil and improve the overall ecology of Planet Earth — including some amazing work Ara & Raja are doing with bee populations.

Seed Offer: As a simple thanks for listening, Ara & Raja have a gift for you. Go to: seed.com/richroll to learn more.

Disclosure: In my opinion, Seed's Daily Synbiotic it is the highest quality probiotic I have tested (which is one of the reasons I wanted to have them on the show). Rigorously evidence-based, I’ve been using this product for the last several months to great effect. However, I have zero financial involvement with the company. Seed is not a show sponsor. Ara & Raja did not pay me to appear on the podcast. (I have never accepted money for a guest to appear on the show and never will). Nor am I an affiliate of Seed. In other words, I get a big zero from you using the above-mentioned discount code other than the satisfaction of sharing a product I myself enjoy.
