Host Rachel Feltman explores the surprising connection between exercise and the gut microbiome with Scientific American contributing editor Lydia Denworth. Drawing from her latest reporting, Denworth explains how aerobic activity can influence the microbial ecosystems in our digestive tract—boosting diversity, reducing inflammation, and even supporting muscle development and mental well-being. From mouse wheels to marathoners, this episode offers a compelling look at why breaking a sweat might be one of the best things you can do for your gut. This episode was made possible by the support of Yakult and produced independently by Scientific American’s board of editors.

  • Understanding the human body is a team effort.

  • That's where the Yakult group comes in.

  • Researchers at Yakult have been delving into the secrets of probiotics for 90 years.

  • Yakult also partners with Nature Portfolio to advance gut microbiome science through the Global Grants for Gut Health,

  • an investigator-led research program.

  • For Scientific American Science Quickly, I'm Rachel Feltman.

  • Over the last couple of decades,

  • few science topics have made a bigger mainstream splash than the microbiome.

  • Our growing understanding of the microbes that live on us, in us,

  • and around us has scientists analyzing and trying to tweak colonies from our armpits to our genitals.

  • But when most of us hear the word microbiome,

  • our minds go first to the diverse ecosystems found within our guts.

  • The communities of bacteria, archaea, viruses,

  • and fungi that live in our digestive tracts have a huge impact on us.

  • Research shows that our gut microbiomes influence how well we digest our food and absorb nutrients.

  • And an imbalance in the microorganisms of the gut is associated with conditions such as type 2 diabetes and non-alcoholic liver disease.

  • Some research even suggests that our gut microbiomes are tied to cognitive function and mental well-being.
