Characteristics of modern wheat High production. Maximum utilization of high energy input in specialized agricultural systems. Selection for technological quality of gluten proteins. Reduction in certain qualitative aspects (reduction in biodiversity of secondary metabolites). Currently, there is a renewed interest in old varieties (defined as varieties in existence prior to intensive selection for gluten quantity and quality) of Triticum aestivum and T. durum and T. spp turanicum, which represent a valuable source of biodiversity in functional components.

Diabetes and diet Diet is thought to be one of the modifiable risk factors for the development of type 2 diabetes mellitus. An increasing interest in modifying the global risk profile of patients with diabetes through modification of dietary habits has been reported in recent years.

Conclusion In the present study we observed that a replacement diet with KAMUT Khorasan products helps patients with a diagnosis of type 2 diabetes to improve their cardiovascular risk profile. This evidence could be of high clinical relevance for reducing the occurrence of a cardiovascular event in these patients
Of interest It is of great interest that the intake of health-promoting properties can be accomplished in the form of a basic staple food choice, such as wheat, which form the basis of the Mediterranean dietary pyramid. The positive effects were not attributable to the fact that KAMUT khorasan was organic semi-whole wheat since the modern durum and soft wheat controls were also cultivated in organic agriculture. The health benefits derived from khorasan are likely attributable, not to single components in isolation, but to potential synergistic effects of numerous components. The positive effects (inflammation in particular) may reside in the existence of novel secondary metabolite molecules or specific polyphenol isoforms that may contain signalling capacities not evident in the conventional varieties
