摘要
Short-chain fatty acids(SCFAs)are major metabolites produced by the gut microbiota through the fermentation of dietary fiber,and they have garnered significant attention due to their close association with host health.As important mediators between the gut microbiota and the host,SCFAs serve as energy substrates for intestinal epithelial cells and maintain homeostasis in host immune and energy metabolism by influencing host epigenetics,activating G protein-coupled receptors,and inhibiting pathogenic microbial infections.This review provides a comprehensive summary of SCFAs synthesis and metabolism and offering an overview of the latest research progress on their roles in protecting gut health,enhancing energy metabolism,mitigating diseases such as cancer,obesity,and diabetes,modulating the gut-brain axis and gut-l ung axis,and promoting bone health.
