07/05/2020 (jkzx.com) — A review of relevant prospective studies published in 2020 in a peer-reviewed journal of the American Cancer Society shows that dietary fiber is associated with reduced risk for breast cancer.
Maryam Farvid, PhD, of the Harvard T.H. Chan School of Public Health, and colleagues analyzed pooled data from 20 observational studies they identified and found that study participants with the highest dietary intake of fiber were 8% less likely to be diagnosed with breast cancer in both pre-menopausal and postmenopausal women.
Dr. Farvid said the study suggests that fiber from foods like fruits, vegetables, and whole grains is an important food component for breast cancer prevention.
The study does not mean that fiber definitely directly renders a protective effect against the development of breast cancer. People eating more fiber (fruits, vegetables and whole grains) could mean that they may be more health conscious and overall follow a good diet and healthy lifestyle, which may collectively contribute to the reduction of the breast cancer risk.
Still dietary fiber may directly or indirectly play a role in the reduction in the breast cancer risk. For instance, dietary fiber can minimize the absorption of fat or fatty acids, particularly from meat and dairy products, which are known to be a risk factor for breast cancer.
