Many studies have reported that dietary fibers play a crucial role in promoting intestinal health of the host, since it strengthens functions of epithelial barrier and meanwhile maintains intestinal homeostasis of the host by modulating gut microbiota and short-chain fatty acid (SCFA) production. Pig is a good animal model to study effects of dietary fiber on gut health and microbial community. This review has summarized the relevant knowledge available based on roles of various dietary fibers in gut health and energy metabolism of pigs and humans. Evidences summarized in our review indicated that modulating intestinal microbial composition and SCFA production by consuming specific dietary fibers properly could be conducive to health improvement and disease prevention of the host. However, types of dietary fiber from edible foods exert divergent impacts on gut health, energy metabolism, microbial composition, and SCFA production. Therefore, more attention should be focused on different responses of various dietary fibers intake on host metabolism and health.
许多研究报告称，膳食纤维在促进宿主肠道健康方面发挥着关键作用，因为它能增强上皮屏障功能，同时通过调节肠道微生物群和短链脂肪酸（SCFA）的产生来维持宿主的肠道内环境稳定。猪是研究膳食纤维对肠道健康和微生物群落影响的良好动物模型。本综述总结了基于各种膳食纤维在猪和人类肠道健康及能量代谢中的作用的现有相关知识。我们综述中总结的证据表明，通过适当摄入特定膳食纤维来调节肠道微生物组成和SCFA的产生，可能有助于改善宿主健康和预防疾病。然而，可食用食物中的膳食纤维类型对肠道健康、能量代谢、微生物组成和SCFA产生具有不同的影响。因此，应更多关注各种膳食纤维摄入量对宿主代谢和健康的不同反应。
