They have another study done by rugby players in Ireland. All right. And they looked at their microbiome, these rugby players, and they discovered that there is a shift within their microbiome towards actually more anti-inflammatory bacteria that interact with fiber to produce what are called short chain fatty acids, which are the most anti-inflammatory molecules out there.

And these short chain fatty acids, which people may have heard of them, butyrate, acetate, propionate. These short chain fatty acids have healing effects right there in your gut. They help to shape the microbiome. They affect the immune system. They affect our metabolism. And they enter the bloodstream and they travel all the way to the brain.

And they affect the brain, including the blood-brain barrier.

Well, it's interesting because you think about all the great athletes, for example, in the NFL. And you see these guys do, like Adrian Peterson comes to mind. where some of the recoveries that he had during his career were crazy. And they defy the rules of recovery. And it makes you wonder if there's something- Is that genetics? Is that microbiome? Is that, yeah.

Are there other factors in play here? But what's interesting is because you have this shift in the microbiome towards these anti-inflammatory molecules. Okay, well, I just mentioned that depression has an inflammatory component to it, right? So here we are and we discover that exercise is actually good for helping our mood.

And what I'm saying is what's happening under the hood, if you lift up the hood and take a look, is there's this shift in the microbiome. And now you don't even have to change your diet. I mean, I do want you to eat more plants. Right, right. Right? But exercise alone helps you improve your anxiety or stress or depression. Yes.

And that shift that's happening in the microbiome is actually helping you to get more from your fiber. Right. So you don't change your diet. You eat the same fiber. Now you get more from it. But what if you also changed your diet at the same time that you were implementing this exercise? If you did one and two, food and exercise. This is why they synergize so well.

I think that the answer is yes. And the reason why I say that is they have these bizarre studies that they've done where they take people and they inject into them something called lipopolysaccharide. What is that? All right. Lipopolysaccharide is produced by bacteria that live inside of us, like E. coli. So we've all heard of E. coli, okay? So this is like- They inject a disease inside of us.

So they're injecting this thing that you find in E. coli into a person's bloodstream. Wow. Okay. And then they track them over the next couple of hours. We're talking about humans. We're not talking about mice right now. And they see what happens. And here's what they find. Number one, because this bacteria has entered into the bloodstream, they get increased levels of inflammation in the body.

Number two, their mood and their motivation to work dips. Wow. All right. Number three, they socially withdraw. All right. So what's going on here? Basically, what I've just told you is that when they inject this E. coli type stuff, which I, by the way, want to unpack that in a quick moment.

Number two, their mood and their motivation to work dips. Wow. All right. Number three, they socially withdraw. All right. So what's going on here? Basically, what I've just told you is that when they inject this E. coli type stuff, which I, by the way, want to unpack that in a quick moment.

When they inject this E. coli based stuff called lipopolysaccharide, it basically activates inflammation and which affects their mood, and it also makes them socially withdrawn. And they think that what's happening is that the body is starting to shut down to preserve energy because it needs to fight the infection. So that's number one.
