Why Cranberries Prevent Urinary Infections
The secret ingredient in cranberries, which is pivotal in preventing urinary infections, is concentrated tannins in the juice, also known as proanthrocyanidins. In a significant study conducted in Boston and published in the Journal of the American Medical Association, cranberry juice was found to be effective in reducing the incidence of urinary tract infections and the need for antibiotic treatments. This has important implications for persons with continent diversions and ostomies for several reasons. Recurrent urinary tract infections can be common with persons who catheterize frequently. These can be more prominent if proper hand washing and cleaning of the catheters is not performed routinely. Furthermore, a large proportion of women over 65 years of age, a major representation, will experience at least one urinary tract infection each year. How does this special ingredient in cranberry juice work? The concentrated tannins from cranberry juice prevent E.Coli bacteria, the main culprit in urinary infections, from adhering to the cells that line the urinary tract. Scientists believe that the substance blocks the growth of the part of the bacteria that is necessary for it to stick to the walls of the bladder and kidney. What are the implications of this for persons who may be more susceptible to urinary tract infections? Scientists in the Boston study state that the addition of cranberry juice to dietary regimens in circumstances where urinary tract infections have a high incidence would be sensible. In addition, it would probably reduce both the incidence of infections and need for antibiotic treatments and be a useful adjunct to treatment in high-risk groups.
