Bile acids are increasingly recognized for their broad metabolic effects, including the regulation of glucose homeostasis. In a recent study published in Nature Metabolism, researchers provide compelling evidence that alteration in bile acid flux — namely, in intestinal absorption and faecal secretion — can directly influence prandial glucose metabolism.
