HealthDay News — High total fiber consumption is associated with a reduced risk for breast cancer, according to a review and meta-analysis published online April 6 in Cancer.

Maryam S. Farvid, PhD, from the Harvard T.H. Chan School of Public Health in Boston, and colleagues conducted a systematic review of prospective studies that reported on the association between fiber consumption and incident breast cancer. Data were included for 17 cohort trials, 2 nested case-control trials, and one clinical trial.

The researchers found that when comparing the risk for the highest vs the lowest category, total fiber consumption was associated with a lower risk for breast cancer (pooled relative risk, 0.92; 95% confidence interval, [CI] 0.88 to 0.95). There was a significant inverse association for soluble fiber with the risk for breast cancer (pooled relative risk, 0.90; 95% CI, 0.84 to 0.96); a suggestive inverse association was seen for insoluble fiber (pooled relative risk, 0.93; 95% CI, 0.86 to 1.00). Lower risks for both premenopausal and postmenopausal breast cancers were seen in association with higher total fiber intake (pooled related risks, 0.82 [95% CI, 0.67 to 0.99] and 0.91 [95% CI, 0.88 to 0.95]).

“The current study findings support the American Cancer Society dietary guidelines to consume foods rich in total fiber, including fruits, vegetables, and whole grains,” the authors write.
