Dietary fiber linked to lower risk for breast cancer 膳食纤维可降低患乳腺癌的风险

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.

膳食纤维可降低患乳腺癌的风险

一项在2020年发表在《美国癌症协会》（American Cancer Society）同行评审期刊上的相关前瞻性研究的综述显示，膳食纤维与降低乳腺癌风险相关。

哈佛大学的Maryam Farvid博士Chan公共卫生学院及其同事分析了他们确定的20项观察性研究的汇总数据，发现绝经前和绝经后女性中膳食纤维摄入量最高的参与者被诊断出患乳腺癌的可能性降低了8％。

Farvid博士说，这项研究表明，水果，蔬菜和全谷物等食物中的纤维是预防乳腺癌的重要食物成分。

该研究并不意味着纤维肯定直接对乳腺癌的发展具有保护作用。人们多吃纤维（水果，蔬菜和全谷类食品）可能意味着他们可能更注重健康，并且总体上遵循良好的饮食习惯和健康的生活方式，这可能共同有助于降低患乳腺癌的风险。

膳食纤维仍然可以直接或间接地在降低乳腺癌风险中发挥作用。例如，膳食纤维可以最大程度地减少脂肪或脂肪酸的吸收，特别是从肉类和奶制品中吸收脂肪或脂肪酸，众所周知，脂肪或脂肪酸是乳腺癌的危险因素。
