And there's no evidence that these microbes, when you drink them, say in a yogurt or a milk kefir,

they stay in your gut and they take over, you know?

So that was always a bit odd.

So how do they work if they don't hang around very long?

You've got to keep drinking them and they have this effect.

And how are they working?

Because they'd be really outnumbered in your gut, you know, because there are billions of them when you drink them, but there's trillions, hundreds of trillions of the other guys, right?

So it's a bit like you going into a football stadium and, you know...

waving your hands around hoping everyone's going to notice you know it's like that scale

So it was a study about three or four years ago by a colleague of mine, Christopher Gardner and Justin Sonnenberg in Stanford, where they gave 28 volunteers really large amounts of fermented food, five portions a day.

They took blood every day on these guys.

And they noticed that after two weeks, they'd reduced the inflammation levels in their blood by about 25%.

And that was the first time anyone had really shown in a proper, really high-level experiment that microbes have this effect.

And evidently, we didn't expect, I didn't anyway, that it would be directly on the immune system, not by just inhabiting our gut microbes.

They're tickling something in our gut that is sending signals to the rest of the body to say, calm down, relax.

It's like having a low dose of steroids, really.

And to me, that was a game changer.

I said, wow, suddenly we've got a mechanism here.

We know how it works.

And then I went and I did it because it was only 28 people, usually young males, as always in these studies.
