Inulin, a non-digestible plant polysaccharide, acts as a prebiotic by selectively promoting the growth of beneficial gut bacteria, such as Bifidobacterium and Anaerostipes, which produce short-chain fatty acids (SCFAs). These SCFAs improve glucose metabolism, reduce inflammation, and enhance metabolic health. Inulin supplementation has been associated with weight management, improved insulin sensitivity, and reduced blood glucose levels, particularly in individuals with obesity or metabolic disorders. The effects of inulin are mediated through its impact on the gut microbiota, leading to changes in microbial composition and SCFA production. Studies show that inulin can improve anthropometric parameters, lipid profiles, and inflammatory markers. However, the specific mechanisms and optimal dosages remain areas of ongoing research. Inulin also shows potential in managing other conditions, such as chronic kidney disease and inflammatory bowel disease, through its prebiotic and anti-inflammatory properties. When combined with other compounds, inulin may enhance its effects on metabolic health, though the interactions and mechanisms require further investigation. Overall, inulin demonstrates significant potential in promoting metabolic health through its influence on the gut microbiota and metabolic pathways.Inulin, a non-digestible plant polysaccharide, acts as a prebiotic by selectively promoting the growth of beneficial gut bacteria, such as Bifidobacterium and Anaerostipes, which produce short-chain fatty acids (SCFAs).
