Monday Dec 10, 2012 (foodconsumer.org) -- For prostate cancer, aggressiveness determines the real risk from the disease. A new study published in Prostate cancer suggests that eating fiber-rich grain foods or even simply taking fiber supplements may help prevent aggressive prostate cancer.

F. Tabung of Arnold School of Public Health, University of South Carolina in Columbia, South Carolina and colleagues conducted the study and found men having the highest intake of total dietary fiber were up to 39 percent less likely to develop aggressive prostate cancer, compared to those having low intakes.

The study involved 930 black men and 993 European American men enrolled in a population-based, case only study - The North Carolina-Louisiana Prostate Cancer Project. Prostate cancer aggressiveness was determined by parameters including Gleanson grade, PSA level and clinical stage.

Exactly, the researchers found men in the second and third tertiles of fiber intake were 30 and 39% reduced risk for aggressive prostate cancer, respectively, compared with those in the lowest tertile of fiber intake.

Fiber from all sources was considered in the calculation of the intake.

The protective effect of dietary fiber against aggressive prostate cancer was more significant among European Americans, compared with African Americans, the risk reduction was 56% versus 43%.

The researchers concluded "Dietary fiber intake was inversely associated with aggressive prostate cancer among both AA (African American) and EA (European American) men."

More than 241,000 American men are expected to be diagnosed with prostate cancer and the disease is expected to kill 28,170 men in 2012 in the U.S., according to the National Cancer Institute.
