Rachel Wermandor: consideration American Americans Science easy, I feel like Rachel.
Within the last couple of decades, some science topics make a larger main prompt microbiome. Our growing understanding of the germs living in us, in us and our surroundings have scientists who have analyzes – and seek to tweak-colonies from our arituan. But if most of us heard the word “microbiome” our thoughts first in different ecosystems found within our guts.

The communities of bacteria, Arkaea, viruses and fungi living in our digestive tracts have a great impact on us. Research shows our gut microbiomes influence how we digest our food and absorb nutrients, and an unbalanced in microorganisms in the gut is associated with conditions Like Type 2 Diabetes and not-liver jewelry. Some research even suggests that our gut microbiomes are tied to cognitive functions and mental well-being: scientists are exploring how autism spectrum disorders, depression, anxiety, ptsd and more could be conveyed to the tiny creatures that live inside us.
But this relationship is not a part: We also have power over our gut microbium – and that exceeds our food choices.
Our guest today is Lydia Denworth, an edition of contribution for American American. He wrote Let me knowScience in Health Health column. In June in the magazine 2025 issues He reported the odd relationship between Gut Mikracot and Exercise. She is now here to tell us more.
Thank you so much for going chatting with us today.
Lydia Denworth: Well here.
Wish: So new you wrote in your column about microbiome, which, of course, many hearers heard their microbiome and thinking of yogurts and probiotics. But you write about the connection to workout. How did you first find the connection?
Denworth: I am at a science conference
I mean, everyone thinks about dieting, probiotics, things like that. And when it was about 15 years ago at the University of Illinois (Urbana-Champaign) he got his Ph.D., and the idea that could be a link between your workout and microbes what you thought was never a thing that anyone thought of. But he knows that people with intestinal disease, specific ulcerative colitis, benefit from exercise. So he thought, “Well, let me investigate, perhaps, what is that.”
So he holds the tires on the wheel – you know, rats like running on the wheels – and he knows that volunteer mice are protected against a colitis mouse and not running no. And so it started there, with this idea that, “Oh, there’s more sight.”
Wish: So now, do you know, more than a decade ago, what do we know about the connection between exercise and the gut microbiome?
Denworth: We know a couple of things. So something is: In people who regularly exercise or elite athletes are different and many microbes in your question, “what else did the germs do?” And that researchers were so different to lose the rabbit hole and said, “Well, why exercise is improving your fitness?”
And what they find is that exercise enlarges the production of germs that produce something called cort-chain fatty acid. And that’s a simple molecule, but it’s something that helps your gut health. It helps reduce inflammation. This is part of your healthy metabolism. So metabolism makes energy, right, and when you exercise and then you make it easier for fattty acids, especially the so-called butigate that your body needs to do with healthy.
Wish: Can you tell us more about what differences in differences in microbiomes of people get this intensity from exercising you know, what does it do to differentiate the germs for us?
Denworth: There is a lot we have never learned about what germs really do against other benefits of exercise, so there are open questions there. But having this healthy, active microbiome they see in athletes and from exercise seemed to increase your ability to workout. It may have been working in the same direction – this is bidirectional.
So research on the other side is just the mice so far. But they know that if, for example, you give rats mice killing the bacteria in their guts, they do not exercise very well and reach them. They also know that a healthy microbiome is as important as muscle development – and then vice versa, right: you are not good musicians who are bad microbiome.
And so everyone at the beginning stages of research, but it is – interesting, right?
Wish: Yes, and do researchers behind it have any specific recommendations for what kind of exercise or what you know, help your microbiome?
Denworth: So far the research has never changed what standard recommendations are, which we participate about 150 minutes of moderate exercise in a week or 75 minutes of exercise in a week. Research suggested that aerobic exercise is more than just training with this effect on other days that we don’t know that we don’t know that we don’t know that we don’t know that we don’t know that we don’t know that we don’t know it’s the same recommendations; It’s more important to go out there and releases your exercise (funny).
Wish: (Funny) perfect. And remind us what general advice is for supporting a good, different, healthy microbiome?
Denworth: Well, food is the number one thing that affects your microbiome – more powerful than workout, I have to say that a good, healthy gut. But then exercise – maybe united with a healthy diet that includes many fiber and doing some great aerobic exercise to be the best combination you give the gut you giving the best gut.
Wish: Great, so more motivation do things we know is good for us (laughs).
Denworth: (Laughs) that’s really.
Wish: Well, thank you so much about joining us today. It’s good.
Denworth: Thanks for having me.
Wish: That’s all for the current period. For more on this subject, check Lydia’s column here online or to print.
