New Haven, Conn.-The risk of prostate cancer may be reduced by consuming more than one serving per week of broccoli, cauliflower, and other cruciferous vegetables, according to Yale School of Medicine researchers.
A team led by Victoria Kirsh, formerly a doctoral student in the Department of Epidemiology & Public Health, reported in the Journal of the National Cancer Institute that men who ate broccoli, cauliflower, cabbage, Brussel sprouts, and turnips were 40 percent less likely to be diagnosed with aggressive prostate cancer compared to men whose diet included very little of these vegetables.
The research team evaluated the association between fruit and vegetable intake and subsequent risk of prostate cancer among over 29,000 men participating in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial.
"Our findings are encouraging in that we noted a pronounced decrease in risk of extraprostatic cancer (Stage III or IV tumors) associated with slightly more than one serving (one half cup) per week of cruciferous vegetables," Kirsh said. "Broccoli and cauliflower had especially strong inverse associations. Aggressive prostate cancer that has spread beyond the prostate is associated with poor prognosis, and therefore identification of potential dietary determinants of this disease is important."
