Polysaccharides from Polygonatum kingianum improve glucose and lipid metabolism in rats fed a high fat diet

Polygonatum kingianum polysaccharides regulated the abundance and diversity of the intestinal microbial community through increasing the relative abundance of SCFA-producing bacteria. This promotes recovery of the intestinal permeability barrier, inhibits LPS entry into the circulation, alleviates inflammation, and prevents glucose and lipid metabolic disorders.
