Native to America, the cranberry is rich in proanthocyanidins; originally a defense mechanism for the plant, these organic substances also are known to naturally help cure urinary tract infections. Recent research in Israel and the USA has concluded that the proanthocyanidins also inhibit the adhesion of bacterial bio-films on teeth. This bio-film adheres to the surface of teeth and forms plaque, which feeds on sugars, producing acids that wear away the tooth surface and dissolve linkages to the gums, eventually leading to destructive periodontal disease and tooth loss. As this bacterial adhesion is the first step in the formation of plaque, cranberries have a unique position in helping to prevent periodontal disease.
