In a study conducted several years ago, three groups of 50 women were monitored for urinary tract infections over 6 months. One group drank cranberry juice daily, another group drank a lactobacillus drink, and the third drank neither of those beverages, serving as the control group. In the control group, 21 women developed at least one infection, compared to 23 of those who consumed the lactobacillus drink and only 6 of those who drank cranberry juice. Does this study provide supporting evidence for the value of cranberry juice in warding off urinary tract infections?
