Cranberry Products Prevent UTIs

Use of cranberry-containing products appears to be associated with the prevention of urinary tract infections in some individuals, according to a study published in Archives of Internal Medicine, a JAMA network publication.

Urinary tract infections (UTIs) are common bacterial infections, and adult women are particularly susceptible. Cranberry-containing products have long been used as a “folk remedy” to prevent the condition, according to the study background.

Chih-Hung Wang, MD, of National Taiwan University Hospital and National Taiwan University College of Medicine, and colleagues reviewed the available medical literature to reevaluate cranberry-containing products for the prevention of UTIs.

“Cranberry-containing products tend to be more effective in women with recurrent UTIs, female populations, children, cranberry juice drinkers, and people using cranberry-containing products more than twice daily,” the authors note.
