Hormonal

Short-chain fatty acids (SCFA) produced by gut microbiota from flavonoid and fiber fermentation influence energy metabolism, glucose-insulin homeostasis, and inflammatory pathways, with effects mediated by G-protein-coupled receptors (GPR).

Support your gut microbiota with fiber and flavonoid-rich foods to promote the production of short-chain fatty acids (SCFA). These byproducts help regulate blood sugar, energy expenditure, and inflammation.

ModerateSupportsMEDIUM confidence
Experimental studies suggest that microbial produced SCFA act as signaling molecules and can influence host energy metabolism, glucose-insulin homeostasis, production of endocrine hormones (eg, GLP-1 [glucagon-like peptide 1]), and inflammatory pathways.
