They're like the building blocks of these chemicals we're talking about.

And the polyphenols, these defense chemicals that give the color to the fruit or the bitterness,

say in olive oil, they're used by the microbes as fuel.

So their extra source of fuel, again, to make them grow better and produce more goodness.

Now, that's what should happen.

And that's what happened to their ancestors.

When we have ultra processed food, UPFs, what happens is that most of that, it's eaten very fast.

It gets mostly absorbed in the upper part of our intestine.

So our microbes generally don't get to see it.

And it has very little fiber in it.

So they're basically being starved of food.

And the sugars and the fats are getting absorbed quite quickly with any modest interaction with our gut microbes.

There's also none of these natural defense chemicals, these polyphenols,

And then you've got these unnatural chemicals like artificial sweeteners, emulsifiers, preservatives, etc., which some of them are absorbed, but others do go into the gut.

where they can cause problems for our gut microbes, make them stick together, make them produce chemicals that might lead to diabetes and have various different effects that we hadn't really thought about 10 years ago.

Well, we get our first microbiome from our mothers, so we need to thank our mothers for that.

And birthing is a messy business, and that's designed that way.

So a bit of your mother's microbiome gets into all our mouths during birth.

And then over the first next four years, we slowly build up this microbiome through breast milk, and that allows us to digest breast milk.

And then increasingly through the diversity of foods, which start to then feed different microbes that we're experiencing in our surroundings when we're picking up animals.
