The worldwide prevalence of diabetes mellitus is expected to reach 439 million by 2030. Diabetes increases the risk for developing secondary complications such as nephropathy and cardiovascular disease, critical factors that dictate the survival rate of diabetes patients. Compelling evidence has indicated that the positive impact of fermentable carbohydrates in obesity-related diabetes is mediated by the production of short-chain fatty acids and the modulation of colonic microbiota. This review summarizes the potential implications of dietary resistant starch, a class of fermentable fiber, in glucose homeostasis and kidney health in obesity-associated diabetes and examines the mechanisms underlying the protective effect of resistant starch. Though extensive clinical studies are still warranted, replacement of simple carbohydrates with resistant starch could be a highly effective alternative dietary strategy to prevent secondary complications resulting from hyperglycemia.
