Fruit and vegetable intake and incidence of bladder cancer in a male prospective cohort.

Cruciferous vegetables may significantly reduce the chances of developing bladder cancer in males although other types of fruits and vegetables appeared to have an insignificant effect. 

This research work was carried out to determine the correlation between the consumption of fruits and vegetables and bladder cancer risk. Using validated dietary questionnaires, researchers analyzed the fruit and vegetable intakes of 47,909 men recruited from the Health Professionals Follow-up Study. The bladder cancer hazard ratio was assessed in all the subjects.

Researchers observed lower incidence of bladder cancer in subjects who consumed large quantities of cruciferous vegetables, such as broccoli and cabbage. However, ingestion of green or yellow leafy vegetables, carotenoid-rich vegetables, and total fruit and vegetable intakes was found to have an insignificant effect on bladder cancer development. The results of this study reveal that decreased bladder cancer risk is associated with high consumption of cruciferous vegetables, but other types of fruits and vegetables may have no effect on the development of this type of cancer in males.
