A Glass a Day Prevents Urinary Infection

LITTLE ROCK, Ark., April 22 (UPI) — A U.S. research chemist suggests daily consumption of a large glass of cranberry juice can help prevent urinary tract infections.

However, Ronald Prior of the U.S. Department of Agriculture in Little Rock, Ark., also says proanthocyanides levels in cranberry products vary and there is a need for standardized testing.


Prior proposes using the new BL-DMAC method as a way of providing a standard, quick and commercially viable measure of cranberry proanthocyanides levels.

Prior and colleagues had proanthocyanides levels analyzed using the BL-DMAC method using 11 powdered samples of cranberry products to five different analytical laboratories — three in the United States, one in China and one in Europe. They found each laboratory reported statistically consistent results.

Prior explains proanthocyanides in cranberry products are molecularly linked together in polymers in such a way that prevents infection-causing bacteria from adhering to cells of the urinary tract.

Other foods such as grapes also contain proanthocyanides, but they lack the linkages that elicit the anti-adhesion effect of cranberry products, Prior says.

The study is published in the Journal of the Science of Food and Agriculture.
