Short Chain Fatty Acids
Short chain fatty acids (SCFA), which include acetate, propionate, and butyrate, are the products of fermentation of insoluble fibre from diet (eg. cellulose, resistant starch) by the bacteria in the gut. These fatty acids have been shown to play an important role in regulating metabolism in the gut and are closely associated with gastrointestinal diseases such as irritable bowel syndrome and other conditions such as obesity. By quantifying SCFA in stool, one can monitor gut health and inflammation.
