Canadian research led by Cancer Care Ontario has found a link between a diet rich in cruciferous vegetables and lower rates of aggressive prostate cancer.
The study examined the eating habits and cancer severity of 1,338 men living with the disease and found that:
Fruit and vegetable consumption was not related to prostate cancer risk overall
Risk of aggressive prostate cancer (stage III or IV) decreased with increased vegetable intake
The most prostate-healthy vegetables were cruciferous vegetables, especially broccoli and cauliflower
Past studies have looked at the link between vegetable intake and prostate cancer risk but findings have been inconsistent and the data on advanced prostate cancer (stage III or IV) is limited.
The current study is part of a larger long-term prospective randomized screening trial (the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial). It is published in the Journal of the National Cancer Institute.
