| Outline of Final Research Achievements |
Several studies have suggested that polyphenols are associated with a reduced risk of developing obesity and metabolic syndrome. The bioavailability is very important in the mechanisms through which polyphenols inhibit obesity and correct energy homeostasis. The role of highly polymeric procyanidins (PP), which are major non-absorbable flavonoids, in the biological effects, is not completely understood. Here, we show that 0.5% PP administration for 12 weeks improved obesity and regulate expression of genes related to lipid metabolism in the diet-induced obesity mice. PP-treatment improved inflammation and the gut permeability. Additionally, microbial 16S rRNA gene sequencing of the cecum demonstrated that PP administration decreased the Firmicutes/Bacteroidetes ratio and increased the proportion of Akkermansia. These data suggest that PPs influence the gut microbiota and the intestinal metabolome to produce beneficial effects on metabolic homeostasis.
