The well-known Fred Hutchinson Cancer Research Center in Seattle Washington is the source for a large recent survey on supplements for cancer prevention. (We’ve already discussed on this blog their 2010 survey highlighting an association between fish oil supplements and lower risk of breast cancer.) This new research, published in May 2011, focuses on grapeseed supplements and reduced risk of prostate cancer.
More than 35,000 male participants from 50 to 76 years old were recruited for a detailed baseline questionnaire in 2000-2002. Upon follow up five years later, 1,602 prostate cancers had been registered among study participants. Any use of grapeseed supplements among the 35,000 participants was associated with a 41% reduced risk of total prostate cancer. There were no associations between prostate cancer risk and use of chondroitin, coenzyme Q10, fish oil, garlic, ginkgo biloba, ginseng, glucosamine, or saw palmetto.
This large survey study follows after a number of preliminary lab studies of the anti-cancer effects of grapeseed. See the Memorial Sloan/Kettering website for more information: http://www.mskcc.org/mskcc/html/69243.cfm
