Can exercise minimize postprandial oxidative stress in patients with type 2 diabetes?
It has recently been estimated by the American Diabetes Association that 21 million Americans, or about 7% of the U.S. population, have diabetes, while an additional 54 million Americans have pre-diabetes. The onset and progression of these disorders and related complications are linked to impairments in glucose and lipid metabolism, both of which are associated with increased production of reactive oxygen and nitrogen species (RONS). Increased RONS production coupled with impaired antioxidant defense (a common finding among patients with diabetes) promotes oxidation of specific biomolecules (lipid, protein, DNA), which can lead to an exacerbation of diabetic complications. While bloodborne variables related to these disorders have traditionally been measured in a fasted state, increasing evidence suggests that measurement of postprandial glycemia, lipemia, and oxidative stress may provide more important clinical information concerning an individual’s susceptibility to diabetes onset a
