The amount of bacteria sticking to the bladder cells was significantly reduced after the bacteria were incubated in urine from women who drank the cranberry juice cocktail, and that effect was two-fold greater after eight ounces of cranberry juice cocktail was consumed than after four ounces was consumed. coli were incubated in the urine samples and combined with human bladder cells. "They even mention it for urinary disorders." In the study, urine was collected from three volunteers before and four to six hours after consumption of 27-percent cranberry juice cocktail. "Cranberry is one of North America's few native fruits, and Native Americans used it for its antibacterial properties," said Amy Howell, PhD, coauthor of the study and a research scientist at the Marucci Center for Blueberry and Cranberry Research at Rutgers University, Chatsworth, N.J. Theoretically, blueberries may prevent UTIs as well, but they need to be further tested in a laboratory and clinical trials, she said. "The next step is to evaluate our findings in a larger group of women, and then conduct a trial to help determine if the laboratory findings translate into clinical differences in the rate of UTI depending on the dosage of cranberry consumed." "There is no evidence that drinking or eating cranberry products can cure a UTI once the bacteria have established infection," said Kalpana Gupta, MD, principal investigator of the University of Washington study. Due to anatomy, women have a higher risk of UTIs than men, and people who experience three or more in one year are considered to have recurrent infections. coli) bacteria (the most common cause of UTI), preventing them from sticking to the walls of the bladder and causing infection.Ī UTI is an infection anywhere in the urinary tract, including the kidneys, the bladder and the urethra. Drinking eight ounces of the juice works better than four in combating the bacteria that cause most urinary tract infections (UTI), according to preliminary research being presented at the 42nd Annual Meeting of the Infectious Diseases Society of America (IDSA).Ī specific type of tannin found only in cranberries and blueberries interacts with the little projections on the Escherichia coli (E. It is important to consult with your doctor and you may need antibiotics.Newswise - Cranberry juice has long been recommended to ward off bladder infections: Now there's evidence that more of the tart drink may be better than less. However, don’t rely on cranberry juice/capsules to fully cure your UTI. Cranberry capsules are concentrated with the antioxidants and active ingredients and are thus a better alternative to cranberry juice. Even cranberry juice with no added sugar (such as Oceanspray 100% cranberry juice) has 28 grams of sugar in 8 fluid ounces of juice. A major drawback is that cranberry juice contains substantial sugar. Moreover, cranberry juice has low concentrations of A-type proanthocyanidins (PACs), so it takes large amounts of juice to have an effect. Thus, cranberries can help with the symptoms of a UTI but should not be depended upon to cure it. However, the active ingredient usually does not stay long enough in the bladder to cure the infection. ![]() Since cranberry juice also increases urination, it might wash bacteria out of the bladder which might reduce the pain and burning associated with UTIs. ![]() UTI’s tend to affect women more than men due to their anatomy.Ĭranberries come into play through an active ingredient-A-type proanthocyanidins (PACs)-that can keep bacteria from sticking to the bladder wall. The real danger, however, is with untreated UTIs which can affect the kidneys and lead to kidney damage or–in very severe instances– infections spread through the blood. ![]() The infection usually starts in the lower urinary tract (urethra and bladder) and causes symptoms such as a burning sensation during urination, frequent urge to urinate, and cloudy or strange-smelling urine. They can affect the urinary system including kidneys, ureters, bladder, and urethra. UTI’s are caused by bacteria such as E.coli. Clinical studies however, offer conflicting results on the effectiveness of cranberry juice. At the top of this list is cranberry juice, which many women claim cured their UTI. There are many myths about what will alleviate UTI symptoms or get rid of the UTI all together. Around 65% of women will experience a urinary tract infection (UTI) in their lifetime.
