Cranberry Proves to Treat Urinary Tract Infections

UTIs and cranberries

Cranberries help fight urinary tract infections according to researchers.

Multiple studies have shown that cranberry can treat and helps prevent urinary tract infections among women and children.

Multiple studies show cranberry benefit for UTIs

This is backed up by consistently positive results among numerous studies. Following all these studies have been multiple reviews of studies that use meta-analysis to gauge the success of UTI treatment with cranberries or cranberry juice. These have concluded that cranberries or cranberry juice reverses and prevents E. coli related urinary tract infections at a rate of 38 percent.

Furthermore, meta-analysis has established that recurrent urinary tract infections are reduced at a rate of 47 percent by the use of cranberry.

Children also benefit from the use of cranberry for urinary tract infections. The latest review from Auburn University  in December, of 2015  analyzed the results of 8 studies on children. It showed that cranberry juice was at least as effective as antibiotics in treating urinary tract infections.

Examples of research reviewed

These reviews calculated the results of multiple studies. Here are a couple of studies they drew from:

Researchers from Finland tested cranberry juice against the number of recurrences of UTI infections among children as well as the need for antimicrobial medications.

In the Finnish study, a total of 263 children received either cranberry juice or a placebo for six months, and then were followed for one year. Approximately half of the children were given the placebo. Through the year, 22% of the children had at least one recurrence of urinary tract infection, while only 16% of the children treated with cranberry juice had recurrent infections – a difference of almost 30%.

Furthermore, the placebo group had 47 episodes of urinary tract infections, while the cranberry group experienced only 27 urinary tract infection episodes. In other words, there were 74% more episodes among the placebo group than among the cranberry group.

In addition, the children who took the cranberry juice required significantly fewer doses of antimicrobial medication than their placebo counterparts.

This recent study confirms a 2009 Catholic University study that found, among 84 girls aged three to fourteen, that consuming concentrated cranberry juice daily reduced UTI recurrence by more than half.

Preventing recurrent infections

Other studies have confirmed that cranberry juice or cranberry capsules significantly reduce urinary tract infections and recurrence among adult women. A 2004 Cochrane review from Edinburgh University analyzed multiple clinical studies on adult women. They concluded that cranberry juice or capsules significantly reduced the number and recurrence of urinary tract infections among adult women.

The mechanism most widely accepted for this is that cranberry alters the pH within the urinary tract mucosal lining, which reduces microorganisms’ ability to adhere (or stick) to the walls of the urinary tract.

Little difference was seen in effectiveness between cranberry capsules and cranberry juice among these studies. Unfortunately, holiday cranberry recipes weren’t tested.

Cranberries also contain a special prebiotic that helps feed our healthy gut bacteria.
