Cranberries Reduce Risk of Urinary Tract Infections


Urinary Tract Infections (UTI’s) affect over 2 million people in the US annually.  UTI’s are especially common among older women.

Cranberries and cranberry juice contain many chemicals- such as vitamin C, flavenoids, anthocyanidins and tannins- which inhibit growth of bacteria and molds (fungi).  Analysis of 665 patients from 4 studies found that daily consumption of cranberries or cranberry juice for a year reduced risk of urinary tract infections by 34%.  (Results were very statistically significant.)

Other studies have reported that cranberries or cranberry juice is about as effective as antibiotics in preventing urinary tract infections.   In addition, the antibiotics have more bad side effects and don’t taste as good as the cranberries.  On the negative side, standard cranberry sauce is loaded with sugar or corn syrup.  Sugar free versions of cranberry sauce can be made or purchased.
