Cranberry Products are Helpful in Fighting Against Urinary Tract Infection
Researchers have supported the finding that cranberry, either in the form of juice or its extract in the form of tablets, is helpful in fighting against urinary tract infections (UTIs). Cranberry is especially helpful for women experiencing recurrent UTIs.
It was already established that cranberries are helpful in fighting against bacterial infections but the mechanism through which this work was unclear. In the recent researches, it has been found that cranberries and possibly other berries stop bacteria from joining to the tissues in the urinary tract resulting in reduced infections.
This study has been reviewed by Dr. Chih-Hung Wang from National Taiwan University Hospital. Wang and his team has studied 10 studies of about 1,494 people, most of them were women, who were given different amounts of cranberry products ranging from one-gram capsules to close to 200 grams of cranberry juice, or placebo or nothing in randomly assigned groups on daily basis.
Researchers found that the participants who were given cranberry products had overall 38% fewer chances of getting UTIs. Moreover, in women with multiple infections, the chances of UTI particularly reduced by 47% while on cranberry products.
"What this is doing is solidifying what has been folklore for quite some time," said Dr. Deborah Wing, who has studied urinary tract infections at the University of California, Irvine.
"Finally, the science is catching up to what our mothers have been telling us for so many decades," she, although not involved in the research, told Reuters Health.
This research has been published online in the Archives of Internal Medicine.
In one of the previous scientific researches, done by researchers from Worcester Polytechnic Institute, it was found that cranberry juice is better in preventing adhesion of bacteria to the tissues than the extracts obtained from cranberries.
On the other hand, this study shows efficacy of cranberry products but these cannot replace antibiotics as reported in the same journal last year.
