Cranberry juice is the juice of the cranberry. The term, used on its own, usually refers to a sweetened version. The information below, regarding sugar content, applies ONLY to sweetened versions of cranberry juice. Unsweetened juice is available at many grocery stores and contains about 70 calories per cup.
Cranberry juice and urinary tract infection
In 2010 a study conducted by the Worcester Polytechnic Institute in Massachusetts found that the ingredients in cranberry juice limit the ability of E. coli bacteria (the main cause of UTIs) to cling to other bacteria. Without other bacteria, E. coli's ability to grow and reproduce is limited. The researchers concluded that cranberry juice helps prevent UTIs, but stopped short of saying the juice cures them. According to WebMD, which reported on the study, study researcher Terri Anne Camesano, PhD, said people should not self-treat urinary tract infections, and anyone who suspects they have an infection should see a doctor, but drinking cranberry juice may be an easy, inexpensive way to help keep E. coli at bay.
There is some evidence that although long-term use of cranberry juice can help prevent symptomatic urinary tract infections, people do not persist in taking it over long periods.[1] There is no significant difference between cranberry juices and capsules. It is thought to prevent adhesion of bacteria such as E. coli to the urinary tract, by inducing changes to their fimbriae.[2]
Interaction with Coumarins
Cranberry juice has been noted to have an effect on Coumarins including Warfarin, causing an unstable INR.[3] The British National Formulary currently advises advoiding concomitant use.[4]
