Cranberries Improve Prostate Symptoms in Six-Month Study

September 22, 2010

Researchers in the Czech Republic claim to have discovered 'the first firm evidence' that cranberries may improve lower urinary tract symptoms (LUTS), according to research published online in the British Journal of Nutrition, this week. The researchers assigned 41 male subjects to 1500 mg of dried powdered cranberries or no cranberry treatment daily, for six months. At baseline, and at three and six months, many prostate-related measures were accessed.

Researchers in the Czech Republic claim to have discovered 'the first firm evidence" that cranberries may improve lower urinary tract symptoms (LUTS), according to research published online in the British Journal of Nutrition, this week.

The researchers assigned 41 male subjects to 1500 mg of dried powdered cranberries or no cranberry treatment daily, for six months. At baseline, and at three and six months, many prostate-related measures were accessed.

At six months, subjects in the treatment group showed statistically significant improvement with several biomarkers, including International Prostate Symptom Score (a commonly used questionnaire rating prostate symptoms), urination parameters, and levels of prostate-specific antigens (which may raise during incidence of prostate cancer).

"The results of the present trial are the first firm evidence that cranberries may ameliorate LUTS," wrote the study's lead researcher.
