It may be the polyphenols.

The polyphenols are what make good extra virgin olive oil bitter, spicy, but it also may be the healthy fats which are contributing to our gut microbiome.

So this is the first sort of wave of research to show this.

And on the flip side, omega-3s, there's now discussion in the scientific community that omega-3s may be prebiotic.

Prebiotic is the term that we use to say something that feeds and nourishes the gut microbiome.

Fiber, resistant starches, polyphenols, these are widely accepted prebiotics.

And now we may need to start to talk about omega-3 fats as being prebiotic because they impact the gut microbiome and then they have a beneficial effect on our health.

Well, so Tim wrote an entire book on this topic.

So of course, anyone who's listening, particularly in the UK, you should grab a copy of this book for sure.

There's some listeners out there right now who they're health conscious.

They've been eating a healthy diet for many years.

And this is the one of the four that they're probably not doing.

The vast majority of us are not because you have to make a conscious decision that you're going to prioritize fermented food in order to get this done.

But research out of Stanford University conducted by Professor Christopher Gardner showed us that on a matter of 10 to 12 weeks, by increasing the fermented food in your diet, you can actually increase the diversity within your gut microbiome and simultaneously reduce the measures of inflammation.

This is partially proof of what we've been discussing this entire time, Jonathan, but also it's exciting.

Because this is a human study showing us that we have something that we can add to our plate and have profound healing effects both in our gut microbiome and immune system at the same time.

There was research that we did similar to the time-restricted eating study.

We activated the Zoe community to start adding fermented food to their plate.

And they went from generally having very close to none to about two serves per day.

And these people who were adding two serves per day, once again, they had improvements in their energy, they had improvements in their mood, they had improvements in their bloating, and they had improvements in their appetite, like their hunger was reduced.
