ShareJuly 25, 2007 — Eating more cruciferous vegetables like broccoli and cauliflower is associated with a reduced risk of aggressive prostate cancer.
Several studies have demonstrated an association between eating vegetables and a reduced risk of prostate cancer, but study results have not been consistent and many have not investigated the association among patients with aggressive prostate cancer.
Victoria Kirsh, Ph.D., of Cancer Care Ontario in Toronto and colleagues evaluated the possible association in 1,338 prostate cancer patients diagnosed in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Each of the men completed a 137-item food-frequency questionnaire.
They found that eating fruits and vegetables was not associated with decreased prostate cancer risk in general. But greater consumption of dark green and cruciferous vegetables, especially broccoli and cauliflower, was associated with a decreased risk of aggressive prostate cancer.
"Aggressive prostate cancer is biologically virulent and associated with poor prognosis. Therefore, if the association that we observed is ultimately found to be causal, a possible means to reduce the burden of this disease may be primary prevention through increased consumption of broccoli, cauliflower, and possibly spinach," the authors write.
