But if it's weak, which I call increased intestinal permeability, but you will hear it referred to as leaky gut.

And I have no problem with that terminology because it's actually correct.

When that happens, it's a weak gut barrier.

Things can sneak across that are not supposed to be there.

And so then your immune system is like, yo, the bloodstream is right behind me.

And I got my like literally age old, like, like this villain that I've been fighting

since before humans existed, right?

The immune cells recognize their enemy, that they have been fighting for literally a billion years.

That's my estimate.

And they go, okay, cool.

You wanna come over here?

We're gonna fight you.

Yeah, so then they get activated.

The immune system gets activated in response to something that got across the gut barrier that's not supposed to be there.

And there's a term for this, by the way, for the people who are nerdy like me.

It's called a lipopolysaccharide.

Lipopolysaccharide is the armor that surrounds like E. coli or Salmonella or Shigella, these nasty bacteria.

This armor, they developed to protect themselves.

And the armor became the way that your immune system identifies the enemy.

Like, oh, you're wearing the armor?
