Prebiotic Fiber Specificity

Meaning

Prebiotic Fiber Specificity describes the precise, differential capacity of various dietary fibers to selectively stimulate the growth and metabolic activity of distinct beneficial bacterial strains within the gut microbiome. Not all fibers are equally effective; their specific chemical structure, chain length, and fermentation characteristics determine which bacterial taxa they feed and, consequently, which health-promoting metabolites are produced. Understanding this specificity is paramount for designing targeted, effective microbiome interventions.
