Study Highlights UTI Benefits of Cranberry Powder
A new study by researchers from Creighton University Medical Center in Omaha adds more science to back the ability of cranberries to prevent urinary tract infections. The study was published in the March 2011 issue of the journal Current Bioactive Compounds.
60 women between 18 and 40 years of age with a history of recurring UTI's were recruited for the study.
The participants were randomly assigned to receive no intervention, a low 500 mg dose of cranberry powder, or a high 1,000 mg daily dose of the powder for 90 days. During the study period, the researchers measured levels of a bacteria called Escherichia coli ("E. coli"). This bacteria is the main cause of urinary tract infections.
The researchers found that the non-intervention group saw no reduction in E. coli. In contrast, the low dose cranberry group saw a 25% reduction and the high dose group saw a 45% percent reduction after 10 days of cranberry consumption. This reduction was maintained for at least 90 days.
The 500mg and 1,000 mg doses were associated with a 36 and 65% reduction respectively in the recurrence of UTI’s. Additionally, 40% of the women who received the cranberry powder reported complete relief from symptoms associated with UTI’s such as itching, burning and frequent urination.
The powder used in the study is called PACran®. It is the first clinically supported and PAC standardized cranberry powder. It is also the first health food ingredient approved by the Korean Food and Drug Administration for a urinary tract health claim.
This study adds yet another layer of science to support the ability of cranberries to reduce the risk and symptoms of UTI's. Cranberries are also packed with numerous beneficial natural vitamins, minerals, dietary fibers and antioxidants. These compounds in cranberries have been shown to provide a lengthy list of health benefits including protection against heart disease, cancer and inflammatory diseases.
