Highly Branched Neo-Fructans (Agavins) Attenuate Metabolic Endotoxemia and Low-Grade Inflammation in Association with Gut Microbiota Modulation on High-Fat Diet-Fed Mice.

Highly branched neo-fructans (agavins) are natural prebiotics found in Agave plants, with a large capacity to mitigate the development of obesity and metabolic syndrome. Here, we investigated the impact of agavins intake on gut microbiota modulation and their metabolites as well as their effect on metabolic endotoxemia and low-grade inflammation in mice fed high-fat diet. Mice were fed with a standard diet (ST) and high-fat diet (HF) alone or plus an agavins supplement (HF+A) for ten weeks.

Modulation of Gut Microbiota of Overweight Mice by Agavins and Their Association with Body Weight Loss.

Agavins consumption has led to accelerated body weight loss in mice. We investigated the changes on cecal microbiota and short-chain fatty acids (SCFA) associated with body weight loss in overweight mice. Firstly, mice were fed with standard (ST5) or high-fat (HF5) diet for five weeks.

Enzymatic Hydrolysis of Agavins to Generate Branched Fructooligosaccharides (a-FOS).

Recently, agavins (branched neo-fructans) of short degree of polymerization have shown beneficial effects on the health of both healthy and overweight individuals. Therefore, the aim of the present work was to investigate the potential use of Agave angustifolia agavins on the generation of branched fructooligosacharides (a-FOS). A.

Agavins reverse the metabolic disorders in overweight mice through the increment of short chain fatty acids and hormones.

In this study, the effects of agavins (branched fructans) along with a diet shift on metabolic parameters, short chain fatty acid (SCFA) production and gastrointestinal hormones in overweight mice were established. Male C57BL/6 mice were fed with a standard (ST) or high fat (HF) diet over the course of 5 weeks, with the objective to induce overweightness in the animals, followed by a diet shift (HF_ST) and a diet shift with agavins (HF_ST + A) or inulin (HF_ST + O) for 5 additional weeks. After the first 5 weeks, the HF group showed a 30% body weight gain and an increase in glucose, triglyceride and cholesterol concentrations of 9%, 79% and 38% respectively when compared to the ST group (P < 0.
