Intricate ecosystem of the human gut microbiome is affected by various environmental factors, genetic makeup of the individual, and diet. Specifically, resistant starch (RS) is indigestible in the small intestine but nourishes the gut microbiota in the colon. Degradation of RS in the gut begins with primary degraders, such as and . Recently, new RS degraders, such as , have been reported. These microorganisms play crucial roles in the transformation of RS into short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate. SCFAs are necessary to maintain optimal intestinal health, regulate inflammation, and protect against various illnesses. This review discusses the effects of RS on gut and highlights its complex interactions with gut flora, especially the family.
人类肠道微生物群的复杂生态系统受到多种环境因素、个体基因组成和饮食的影响。具体而言,抗性淀粉(RS)在小肠中不可消化,但能滋养结肠中的肠道微生物群。肠道中RS的降解始于初级降解菌,如[具体细菌1]和[具体细菌2]。最近,已报道了新的RS降解菌,如[具体细菌3]。这些微生物在将RS转化为短链脂肪酸(SCFA)(如乙酸盐、丙酸盐和丁酸盐)的过程中发挥着关键作用。短链脂肪酸对于维持最佳肠道健康、调节炎症以及预防各种疾病是必不可少的。本综述讨论了RS对肠道的影响,并强调了其与肠道菌群,尤其是[具体菌科]的复杂相互作用。
