Cranberry Juice does not prevent recurrent Urinary Tract Infection in a clinical trial


Professor Betsy Foxman, Director, Center of Molecular and Clinical Epidemiology of infectious diseases at University of Michigan School of Public Health led a double-blind, placebo controlled trial on the effectiveness of Cranberry Juice in preventing urinary tract infectious. The research concluded that drinking 8 oz of 27% of Cranberry juic daily did not prevent a recurrence of UTI.  To read this article published in the 2011 you may click here.

This article definitely shows that people have to be careful in avoiding the sources of recurrent UTI. This study was done on college girls.  UTI patients might prevent a recurrence by avoiding unhygenic conditions that perhaps present the UTI causal agent.

Cranberry juice has health benefits touted through centuries. This study does show that it does not replace the need to follow hygenic practices in prevention. Modern science has been unable to explain the total health benefits of a natural food. Perhaps, a simultaneous question one could have added during the study is whether the general health of the college girl drinking Cranberry juice was better than the girls on placebo, given all other life style factors being equal. Perhaps, Cranberry prevents further downstream complications arising from a UTI. We look forward to the research on Cranberries. It benefits all to have a better scientific understanding of the natural world around us.

Cranberries are highly sought after. They are packed with nutrients and antioxidants. The benefits of a natural source of nutrients and antioxidants cannot be underestimated. They have developed an ability to grow under extremely challenging conditions in bogs. Natural Cranberry farmers take great efforts in maintain their Cranberry bogs in pristine condition. To read Russel Avery’s wonderful article on “How Cranberry Bogs Work” click here. It is a fascinating presentation on the farmer’s efforts to keep Cranberry crops strong. It makes one respect the juice we ingest so quickly.
