[Cranberry juice and urinary tract infection].
Cranberries have long been the focus of interest for their beneficial effects in preventing urinary tract infections (UTIs). Cranberries contain two compounds with anti-adherence properties, which prevent fimbriated E. coli from adhering to uroepithelial cells in the urinary tract. Approximately a dozen clinical trials have been performed testing the effects of cranberries on the urinary tract. However, these trials have a number of apparent limitations. Most importantly, the trials have used a wide variety of cranberry products, such as cranberry juice concentrate, juice cocktail, and cranberry capsules, and have employed different dosing regimens. Further research is required to clarify unanswered questions regarding the role of cranberries in protecting against UTI in general and in women with anatomical abnormalities in particular.
