Ancient wheats: beneficial effects on insulin resistance.

Non-alcoholic fatty liver disease and type 2 diabetes mellitus are two conditions that commonly co-exist in the context of metabolic syndrome. Several scientific advances in understanding this association have identified insulin resistance as the key point in the pathogenesis of both diseases. The first line treatment suggested in the management of these diseases is represented by lifestyle changes, and in particular, the modification of alimentary regimen, with the transition to a healthy diet. In this context, several studies have focused their attention on the identification of food products with beneficial actions, like ancient wheat (AW). AW is defined as the early cereals that were domesticated in their places of origin in the "Fertile Crescent" of the Middle East, and played a central role as a main source of food for the early civilizations in that region. The present narrative review aims at providing a systematic overview of the state of the art on the effects of AW on insulin resistance.
