NewsScientists unlock gut-healing power of fruits and nuts paired with the right gut microbes
Scientists discovered how a naturally occurring microbial metabolite called urolithin A, which is generated by gut bacteria after digestion of foods such as pomegranates, walnuts and berries, activates a protective pathway in the intestine that may help preserve gut health.
