Beside the fact in this study that it is significant to men than women(?), we must take that consistently vegetables may lower colorectal cancer.
Our study, consistent with findings from the Cancer Prevention Study II Nutrition Cohort Study (observed that vegetable intake was related to lower risk of colorectal cancer for men but not for women. This gender difference may be partially explained by differential reporting errors. Studies have found that healthful attitudes, beliefs, and dietary habits were more strongly correlated with vegetable intake among women than among men and that women overreported foods perceived as healthy. Misreporting of fruit and vegetable intakes by women in our study would have led to exposure misclassification, resulting in an attenuated association.
In this large, prospective cohort study with 2,972 incident colorectal cancer cases and extensive information on diet and other colorectal cancer risk factors, the researcher observed that vegetable intake was associated with a lower risk of colorectal cancer for men but not for women. The association was stronger among individuals with very low intakes of fruits and vegetables, suggesting a certain minimum amount of daily fruit and vegetable consumption to avoid increased risk of colorectal cancer. Among subgroups of vegetables, green leafy vegetable intake was inversely associated with risk of colorectal cancer for men.
