Digestive properties in fermentation driven interactions of plant polysaccharides with gut microbiota and their health implications

Plant polysaccharides, as pivotal dietary metabolites, primarily exert their health-promoting effects through interactions with the gut microbiota. These carbohydrates are resistant to digestion in the upper gastrointestinal tract and can reach the colon intact, where they are fermented by the gut microbiota to produce a variety of bioactive metabolites. Notably, the bioactivities of plant polysaccharides rely on microbial fermentation rather than direct absorption by the host. Gut microorganism
