Polyphenols in plant diets were found to be beneficial to human health in several aspects, including postprandial glycemic control by the inhibition of carbohydrate digestion and absorption. This effect is similar to acarbose, a medicine used in diabetics for glycemic control purpose. Therefore, there is a possibility of using polyphenols-rich sources in the production of medicines, supplements and functional foods which can be a part of daily diet. This review study summarized the knowledge about the relation between polyphenols-rich diets and postprandial glycemic control, including possible mechanisms, in vitro studies and human studies, especially in an aspect of receiving polyphenols in a form of normal diets. The result found that polyphenols-rich diets extract showed positive results in many in vitro studies. However, the results among human studies using polyphenols sources in the form and amount that present in daily diet were contradictory. More human studies should be undertaken, especially in aspects of types, forms and doses of polyphenols-rich diets that lead to positive results, in order to obtain more evidence for final conclusion.
