ANN ARBOR, Mich., Dec. 11 — A U.S. researcher says cranberry juice may be no more effective than a placebo against urinary tract infections.
Study author Betsy Foxman of the University of Michigan School of Public Health in Ann Arbor says they expected a 30 percent recurrence rate in those in the placebo group.
However, Foxman reports their study, published in the January issue of Clinical Infectious Diseases, found the cranberry juice drinkers had a recurrence of urinary tract infections at a rate of almost 20 percent, while those who drank the placebo suffered only a 14 percent recurrence.
However, Foxman notes the possibility the placebo juice inadvertently contained the active ingredients that reduce urinary tract infection risk, since both juices had vitamin C.
