The latest word on drinking cranberry juice to prevent urinary tract infections is that it really does work. Researchers in Taiwan analyzed the data from 13 studies that compared the use of cranberry juice or products containing cranberries to placebos. They found that cranberry juice works better than cranberry supplements and that those who benefited most were women (especially women who had recurrent urinary tract infections) and children. They also found that individuals who consumed cranberry products twice a day received more protection than those who took them less often. The investigators suggested that cranberry juice might be more effective because of the effect of unidentified substances in the juice that aren’t found in cranberry supplements. They concluded that drinking cranberry juice or taking cranberry supplements could reduce the incidence of urinary tract infections in high risk people - pregnant women, the elderly and individuals with under-active bladders due to nervous system damage. The study was published in the July 9, 2012, issue of the Archives of Internal Medicine.
