膳食纤维和益生菌对健康影响知多少？

“Dietary fiber intake and use of probiotic supplements have also been shown to affect the composition of gut bacteria. More cancer patients are taking probiotic supplements in an effort to improve their gut health, but little is known about how probiotics—which basically change the ecology of the gut bacteria

“膳食纤维的摄入和益生菌补充剂的使用也被证明会影响肠道细菌的组成。为了改善肠道健康，越来越多的癌症患者开始服用益生菌补充剂，但人们对益生菌是如何从根本上改变肠道细菌生态的知之甚少。

Among the 128 patients whose dietary fiber intake was known, those who reported consuming at least 20 grams of dietary fiber per day (an amount the researchers designated as “sufficient” for the purposes of this study) lived longer without their cancer progressing than those who consumed less dietary fiber. Every 5-gram increase in daily dietary fiber intake corresponded to a 30% lower risk of progression of the disease.

在已知的 128 名膳食纤维摄入量的患者中，那些每天至少摄入 20 克膳食纤维的患者（研究人员为这项研究的目的指定的“足够”量）比那些摄入较少膳食纤维的人活得更长，他们的癌症没有进展。每日膳食纤维摄入量每增加 5 克，疾病进展的风险降低 30 %。
