So this sorts that out.

It's looking a bit like the genetics.

People have been following the genetics revolution.

20 years ago, we thought there was just one gene per disease.

We just thought in Crohn's or ulcerative colitis, you just got one gene and then you measure everyone.

Again, human biology is much more complex.

And so we also know that unlike genetics, all of us are much more unique in our gut microbes.

So we need very big databases to work out what the...

you know, how you would commonly assess, say, even the three of us to say who's healthier in terms of gut microbes because we've got to have the same group that are common between us in order to compare them.

No point you and I comparing if we only share, on average, you know, 20% of them.

So, yeah, it's really complicated, but the good news is we're making progress really fast because now, thanks to all the Zoe members, we're getting this vast database that is doing things that no one else can do.

What would you add, Tim?

Two things.

I think fermented food has been shown, thanks to a study from Stanford, to have anti-inflammatory effects, which means we get this boost of extra microbes that are in food and the probiotics in food if you have them regularly.

And we're talking at least probably 3%.

times a day, you're getting a sample of it, can dampen down inflammation, keep your immune system in much better shape, less likely to cause these problems, which that visceral fat we think thrives off.

So I think the idea is to keep that inflammation down.

And the other...

The other thing in addition to what Suzanne said is avoiding ultra-processed foods as much as possible.

It's pretty impossible to cut them out completely, but get it down to less than 10% of your diet so that you're getting many whole foods because we know that there's a pro-inflammatory reaction when you're having a lot of these foods and it causes problems for your gut microbes as well as depriving them of fiber and normal nutrients.
