Cover Story: An tea, renowned for its unique post-fermentation process, offers more than just a rich flavor and aroma. This research highlights the remarkable potential of An tea polysaccharides (ATPSs) as prebiotics. In vitro studies reveal that ATPSs withstand digestive processes, reaching the gut intact, where they undergo fermentation. This process not only reduces pathogenic bacteria like Desulfovibrio and Escherichia, but also boosts beneficial genera such as Lactobacillus, Bifidobacterium, and Prevotella. Additionally, ATPSs increase short-chain fatty acids (SCFAs), crucial for gut health. In vivo experiments on C57BL/6J mice further confirm these benefits, showing elevated levels of Lactobacillus and Bifidobacterium. These findings position ATPSs as promising prebiotics, capable of enhancing gut microbiota and overall human health. View this paper
