meta-analysis confirms cranberry prevents urinary tract infections

Researchers say doctors should be recommending cranberry to their patients for fighting urinary tract infections. . . .

An important new meta-analysis has concluded that taking cranberry is a powerful way to reduce urinary tract infection and antibiotic use.

The meta-analysis included 28 studies of almost 5,000 people and was published in the official journal of the American Urological Association. It “clearly showed” that cranberry significantly reduces the incidence of urinary tract infections by 32.5%.

The researchers conclude that this systematic review “could be used by physicians to recommend cranberry ingestion to decrease the incidence of urinary tract infections, particularly in individuals with recurrent urinary tract infections.” They also point out that using cranberry instead of antibiotics would help in the world wide crisis of antibiotic resistance.

This researchers say that the main mechanism of cranberry may be the ability of cranberry proanthocyanidins—powerful flavonoid antioxidants—to prevent bacteria from adhering to the urinary tract wall. This under appreciated ability of cranberry has long been known to be the real answer to the mystery of how cranberry works and was recently confirmed once again by research.
