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. This research was published recently in the Journal of the National Cancer Institute.
