A new study confirms that cranberry juice and other cranberry products can help prevent UTIs in some people.
But it may take more than a glass of cranberry juice in the morning to do the trick, and cranberries may benefit some people more than others.
Each year in the U.S., UTIs cause more than 7,000,000 doctor visits and 100,000 hospitalizations, according to statistics cited in the new study, published in the Archives of Internal Medicine.

Cranberries Combat UTIs
For the study, researchers evaluated the effectiveness of cranberries in preventing UTIs in 13 studies involving more than 1,600 people.
Overall, the results showed that UTIs were 38% rarer among people who used cranberry products (juice or supplements) than those who didn't.
Cranberry products were found to be more effective in preventing UTIs in certain groups of people.
"Cranberry-containing products tend to be more effective in women with recurrent UTIs, [women], children, cranberry juice drinkers, and people using cranberry-containing products more than twice daily," write the researchers, who included Chih-Hung Wang, MD, of National Taiwan University in Taipei, Taiwan.
