Main description:

This SpringerBrief focuses on clinical nutrition research, particularly on the effects of slowly absorbed carbohydrates on postprandial glucose metabolism in type 2 diabetes. Slowlyabsorbed carbohydrates will cause gradual increases in blood glucose and insulin levels, and may therefore be effective as part of a treatment strategy for glycemic control and reduction of cardiovascular complications in type 2 diabetes.
