“For the first time, the research has begun to reveal the biochemical and biophysical mechanisms that appear to underlie a number of beneficial health effects that have long been ascribed to cranberries and cranberry juice–in particular, the ability of cranberry juice to prevent urinary tract infections (UTIs).

The mechanism by which cranberry juice prevents such infections has not been clear, though scientists have suspected that compounds in the juice somehow prevent bacteria from adhering to the lining of the urinary tract.”
