PLEASE NOTE: This trial has been registered retrospectively. Trial Description Title Investigation of the effect of isomaltulose (PalatinoseTM) on metabolic parameters in subjects with Type 2 Diabetes. Trial Acronym ISODIA URL of the trial [---]* Brief Summary in Lay Language The study investigates the effect of replacing 50g sucrose per day by isomaltulose in sweet food and beverages on metabolic control in subjects with type 2 diabetes. The study tests the hypothesis, whether isomaltulose vs. sucrose results in improved glycemic control assessed as HbA1c after 12 weeks. Brief Summary in Scientific Language The study investigates the effect of replacing 50g sucrose per day by the low-glycemic sugar isomaltulose in sweet food and beverages on metabolic control in subjects with type 2 diabetes under free-living conditions. Primary endpoint of the study is HbA1c at 12 weeks after study start. The aim of study is to test the hypothesis whether replacing 50 g/d sucrose by isomaltulose in sweet foods and beverages over a period of 12 weeks would result in improved glycemic control assessed as HbA1c as and metabolic parameters associated with cardiovascular risk in individuals with type 2 diabetes.
