From the story here:
The participants assigned to the cranberry powder group displayed notable improvements in their flow-mediated dilations (FMD). Study authors say FMD signals both heart and blood vessel function improvements.
Scientists consider FMD an important and sensitive biomarker of one’s cardiovascular disease risk, measuring the widening of blood vessels when blood flow increases.
It’s also important to note that the FMD improvements among participants were apparent within just two hours of consuming cranberry powder, with the beneficial effects remaining after one month of daily consumption. This suggests eating cranberries is great for the heart in both the immediate short term and over the long haul.
