Recent research suggests that cranberry juice may not be effective in preventing painful bladder infections often incurred by women, BBC News reported.
For years, cranberry juice has been thought to protect again cystitis, the inflammation of the bladder, often caused by a urinary tract infection.
Researchers from the University of Stirling in Scotland conducted a study involving close to 4500 subjects, in which the results proved that cranberries did not provide any protection against cystitis.
University researchers said that the original thought was that cranberries may prevent bacteria from sticking to the cells lining the urinary tract.
The majority of the studies showed no benefits of cranberry juice to women with recurring bladder infections. To prevent one bladder infection, subjects would have to drink two glasses of cranberry juice every day.
“We can’t see a particular need for more studies of the effect of cranberry juice, as the majority of existing studies indicate that the benefit is small at best, and the studies have high drop-out rates,” Dr. Ruth Jepson, lead researcher from the University of Stirling told BBC News.
