Plumsmart Plum Juice Clinically Proven to Help Regulate Digestion, NaturallyCheryl Forberg, RD, discusses the health benefits of PlumSmart fresh plum juice. A recent study published in The Internet Journal of Nutrition and Wellness (volume 7, number 2) showed that PlumSmart helps regulate digestion, and that participants preferred the taste of the crisp, all-natural juice. PlumSmart 100% juice was found to be just as effective at providing relief from irregularity as the leading fiber supplement. Cheryl is a member of the Sunsweet Nutrition Advisory Council.
