Gut microbes and poor artery health – researchers probe possible link

March 1, 2017

Preliminary evidence shows changes in gut microbiota could contribute to poor artery health with aging. This condition is worsened by eating a "Western diet" high in fat and sugars and low in fiber. With a $3 million grant, CU Boulder researchers are investigating further.
