High-fiber diet linked with reduced breast cancer risk

Fiber consumption may significantly reduce the risk of breast cancer, according to new research from Harvard T.H. Chan School of Public Health.

The study, which pooled data from 20 previous studies, found that women who consumed the highest amounts of fiber were 8% less likely to develop breast cancer than those who consumed the least.

Researchers believe that fiber may reduce breast cancer risk by controlling blood sugar and decreasing estrogen levels, according to an April 5, 2020 article in the Daily Mail. Sources of fiber include fruits and vegetables, whole grains, legumes, seeds, and nuts.

“Our study contributes to the evidence that lifestyle factors, such as modifiable dietary practices, may affect breast cancer risk,” said lead author Maryam Farvid, research scientist in the Department of Epidemiology.
