Background: Catechol, 1,2-dihydroxybenzene, prepared through bacterial biotransformation from higher order polyphenols, has been proposed to regulate carbohydrate metabolism, especially in the context of type 2 diabetes. This review aims to contextualize this finding. It describes the bacterial biosynthesis of catechol both from glucose, and as a degradation product of higher order natural products through bacterial transformation. The review then considers the mechanism of action of glycemic-regulating catechol-containing materials and the complications arising from balancing their inherent activity with that of catechol, their common degradation product. It then enumerates potential dietary sources of catechin from common foods. Methods: Articles were found …
