MONDAY, April 6, 2020 (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<\/i>.<\/p>\n
Maryam S. Farvid, Ph.D., 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, two nested case-control trials, and one clinical trial.<\/p>\n
The researchers found that when comparing the risk for the highest versus the lowest category, total fiber consumption was associated with a lower risk for breast cancer (pooled relative risk, 0.92; 95 percent confidence interval, 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 percent confidence interval, 0.84 to 0.96); a suggestive inverse association was seen for insoluble fiber (pooled relative risk, 0.93; 95 percent confidence interval, 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 percent confidence interval, 0.67 to 0.99] and 0.91 [95 percent confidence interval, 0.88 to 0.95]).<\/p>\n
“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.<\/p>\n
