For decades women have been told that cranberries can be used to treat or prevent common urinary tract infections (UTIs) — at least that’s what our moms told us! However, a new study out of Stirling University shows that any benefit women may have from cranberry juice or tablets is limited at best, reports ABC News.

The rationale for the long-held home remedy was that the enzyme flavanol, found in cranberries, kept bacteria from attaching to cells in the urinary tract, thereby preventing infection. But it turns out that based on a review of over 20 studies involving almost 5000 subjects, cranberry juice is only helpful for a small group of women — mostly those with recurrent UTIs.

In fact, the research showed that those without chronic infections would need to consume at least two glasses of real cranberry juice — not the sugary juice cocktail variety — over an extended period of time in order to actually prevent an infection.

And, no, it doesn’t count if you just mix cranberry with vodka — nice try, though!
