Fermented Foods as Functional Systems: Microbial Communities and Metabolites Influencing Gut Health and Systemic Outcomes

Fermented foods represent an intricate ecosystem that delivers live microbes and numerous metabolites, influencing gut health. In this review, we explore how complex microbial communities and metabolites generated during food fermentation modulate the gut microbiome and affect human health. We discuss fermentation-induced biochemical transformations, including enhanced fiber fermentability; nutrient availability; and the synthesis of bioactive metabolites such as short-chain fatty acids, exopolysaccharides, bacteriocins, and modified polyphenols. We describe the dynamic microbial ecology of fermented foods, influenced by ingredient variations, highlighting its effect on health-related metabolic outcomes.…
