Grape Seed Extract supplements reduce prostate cancer risk
Researchers at the Cancer Prevention Program, Fred Hutchinson Cancer Research Center in Seattle examined if nonvitamin, nonmineral specialty supplements cut the risk of prostate cancer using data from the VITamins and Lifestyle (VITAL) cohort.
The 35,239 men in the study ranged in age from 50-76 years and were residents of western Washington State. and who completed an extensive baseline questionnaire in 2000-2002. Participants responded about their frequency (days/week) and duration (years) of specialty supplement uses.
1,602 incident invasive prostate cancers were obtained from the Surveillance, Epidemiology, and End Results registry. Multivariate-adjusted hazards ratios (HR) and 95% confidence intervals were estimated by Cox proportional hazards models. Any use of Grapeseed Ext6ract supplements was associated with a 41% reduced risk of total prostate cancer. The study results are published in the May 2011 issue of the journal Nutrition and Cancer.
