And Justin Sonnenburg and Erica Sonnenburg, who are leaders in this field, look to the day for precision medicine when we can do that, and it is not today.

Christopher GardnerGUEST
It's just so exciting.
Christopher GardnerGUEST
I actually have a fun story to tell you.
Christopher GardnerGUEST
One time, one of my first studies with Justin Sonnenburg doing the microbiome, he sat in as I was giving a pitch to the first group of potential participants.
Christopher GardnerGUEST
And I said, "You know, if you aren't willing to do both of them, just don't do it.
Christopher GardnerGUEST
Just walk away, read about it later." And at that point, he sort of lost his shit and he thought, "Oh my God, is this what you do for a living, Christopher? You're, you're practically telling them not to do the study?" And a couple did walk away, and the rest stayed, and the retention was high.
Ping HuangCORRESPONDENT
Yet researchers compared their gut bacteria and found they had ninety percent of the same species in their digestive tracts.
Ping HuangCORRESPONDENT
Justin Sonnenburg at Stanford University is senior author on the paper.

These populations in South America and in Africa and probably in other parts of the world are transmitting microbes over generations.
Ping HuangCORRESPONDENT
The similarities in their gut bacteria are remarkable.

What's been really phenomenal over the past 10 to 15 years is that we- there's been this awakening that this gut microbial community is essential for our health.
Nicola TwilleyHOST
Justin Sonnenburg is a professor of microbiology and immunology at Stanford University and a leader in this wildly exciting and pretty new field of gut microbiome research.
Nicola TwilleyHOST
So what does this all mean? Why is it so important that fiber is feeding microbes in our gut? And fiber and those microbes, how are they all affecting our health, and what does this mean about what we should be eating? That's coming up after the break.

When it comes to your business, you want cards and tools you can trust.
Cassie GroeschlHOST
And so one fermented food, maybe it's Greek yogurt with live active cultures, maybe it's kefir which is fermented milk, sauerkraut, kimchi, another fermented food that works for you.
Cassie GroeschlHOST
The reason why I-- it's so important to add fermented foods is based on research by Justin Sonnenburg et al when they looked at two different groups adding fiber to one and fermented foods to the other.
Cassie GroeschlHOST
They actually found more reduction in inflammatory markers in the group that added more fermented foods to their diet.
Cassie GroeschlHOST
So we're not gonna have you add multiple fermented foods.
Andrew HubermanHOST
I'll try and make this very quick.
Andrew HubermanHOST
Justin Sonnenburg, my colleague who you know-
Michael PollanGUEST
Yeah
Andrew HubermanHOST
... at Stanford working on the microbiome, scared, I wanna say the shit out of me, but then pun, no pun intended, when he said, you know, these microbiota that live in all of us and create these critical chemicals for brain health and all, and it can impact our behavior, whether or not we feel sick or more energetic, more outgoing, I mean, there's this incredible array of-
