Agave salmiana fructans as gut health promoters: Prebiotic activity and inflammatory response in Wistar healthy rats

Abstract Prebiotic effects of Agave salmiana fructans at five different doses were evaluated by the growth of Bifidobacterium , Lactobacillus , and Clostridium strains and SCFA production in the cecum and proximal colon of healthy Wistar rats. Mucosal integrity, bacterial proliferation, and inflammatory response were also examined. Growth of Bifidobacterium and Lactobacillus strains was improved by 12.5% doses of fructans in both cecum and proximal colon tissues, and a significant decrease of Clostridium (P  Agave salmiana fructans, demonstrating that a diet supplemented with a 12.5% dose of fructans promotes major growth of probiotic bacteria and could be used as a potential prebiotic ingredient under the conditions used in this study. Taken together, these results further indicate the significance of Agave salmiana fructans as a prebiotic ingredient in the regulation and prevention of gastrointestinal diseases, as well as for the design of functional foods.
