A collaborative study with Ikuo Kimura at Kyoto University has revealed that Streptococcus salivarius, a common resident of the human gastrointestinal tract, and the indigestible polysaccharide (EPS) it produces from sucrose, may help prevent sucrose-induced obesity by improving the gut environment.
These findings suggest a novel mechanism by which gut-resident bacteria contribute to metabolic health.
The results of this study have been published online in Nature Communications.
