Scientists know that our microbiome, it's not just involved in digestion. It's intimately linked with so much of our overall health. It influences our immune system, our mental health, our cognition, and much, much more. Some of these links are only beginning to be fully revealed.
You're listening to LifeKit. I'm Mariel Segarra. And that was NPR health correspondent Will Stone. The gut microbiome is a way of describing the literally trillions of microbes that populate our intestines.
A lot of these are bacteria, but we also have other organisms in there, fungi and viruses. So you want to picture this packed, dense ecosystem that's alive within you.
Now given what scientists are discovering, that the microbiome is important to our health, people want to hack it. They want to have the very best, healthiest microbiome possible. Will says the problem is the science hasn't come quite that far yet.
Scientists haven't quite figured out how to even define what is a healthy microbiome. There's a lot of variability when you look around the world, depending on where you live, your diet, all kinds of things. And so unless you are acutely ill and are having symptoms, it's hard to pin down what is healthy.
We do have some clues, though. It seems that the more diverse your gut bacteria are, the better. Also, if your microbiome bounces back well from disruption, like antibiotic use, that's a good sign.
And another area that scientists can look at are the different groups of bacteria that are present in your microbiome. And we know that some are associated with better health. When you look around the world, you see this.
On this episode of Life Kit, best practices for your gut microbiome. I talked to Will about probiotic supplements, microbiome tests, and what you eat, which is still the most important factor here.

It's easy to feel overwhelmed by skincare advice. Somewhere along the way, skincare got complicated and started to feel like a job.

Well, there's a huge market for gut microbiome tests. Are any of these worth spending money on?
The short answer is generally no, at least when you look around the huge variety of products out there. And that's because they tend to overstate the science and be way ahead of the evidence. So just to run through a couple of these, you have these gut microbiome tests that you can buy.
