Cruciferous vegetables intake is associated with lower risk of renal cell carcinoma: evidence from a meta-analysis of observational studies.

Americans who regularly consume cruciferous vegetables are less likely to develop renal cell carcinoma than those who do not.

This research work investigated the correlation between cruciferous vegetables intake and renal cell carcinoma risk. Researchers analyzed data obtained from 12 studies conducted in America and Europe that examined 1,228,518 healthy subjects and 5,773 renal cancer patients.

Researchers observed a low prevalence of renal cancer among American subjects who frequently consumed high quantities of cruciferous vegetables. Surprisingly, high intake of cruciferous vegetables was found to have little or no effect on renal cell carcinoma risk in European subjects. The findings of this meta-analysis show that consistent consumption of cruciferous vegetables may help to protect Americans against the development of renal cancer.
