Dietary fiber and whole-grain consumption in relation to colorectal cancer in the NIH-AARP Diet and Health Study
Total dietary fiber intake was not associated with colorectal cancer risk, but whole-grain consumption was associated with a modest reduced risk of colorectal cancer in the National Institutes of Health-AARP Diet and Health Study. A total of 2,974 incident colorectal cancer cases were identified during 5 years of follow-up in a cohort of 291,988 men and 197,623 women ages 50-71. In analyses of fiber from different food sources, fiber specifically from whole grains was associated with a lower risk of colorectal cancer. This inverse association with fiber from whole grains was stronger for rectal than for colon cancer.
