A study by Cornell University's New York State Agricultural Experiment Station and the University of Rochester Medical Center suggests that red wine grapes may help prevent tooth decay.
The researchers found that red wine grapes from the Finger Lakes and pomace, the residue remaining after winemaking that can also be used to make grappa, contain substances that help prevent dental problems. Polyphenols in the grapes interfere with the ability of bacteria to to cause tooth decay. The researchers think this might help kill other harmful bacteria that causes more serious health problems.
The study appeared on the Journal of Agricultural and Food Chemistry website.
