Scientists Think the Real Fountain of Youth May Be Hiding in Your Gut

Researchers say the gut microbiome changes with age and may influence inflammation, metabolism, and lifespan.

Mouse studies and data from older adults suggest that a more youthful microbiome is linked to healthier aging.

Diet and exercise may help preserve a healthier microbiome, while ultraprocessed foods may work against it.

Scientists are also seeking safer ways to reshape the microbiome than fecal transplants, which carry risks.
