Satiety, glycemic profiles, total antioxidant capacity, and postprandial glycemic responses to different sugars in healthy Malaysian adults.

Objectives. We investigated a low-glycemic index (GI), minimally refined brown sugar (MRBS) that retains a consistent amount of antioxidant polyphenols. This study aimed to determine whether MRBS has a lower postprandial glycemic response and GI value compared with other types of refined sugar (RS). Low glycemic response foods are also reported to increase satiety. Accordingly, we also evaluated satiety profiles, glycemic profiles (glucose, insulin, and glucagon), and total antioxidant capacity (TAC). Methods. This work shows the results of two single-blind, cross-over studies (studies 1 and 2). For each study 14 healthy Malay individuals with a normal body mass index were recruited. In study 1, capillary blood samples were used to determine the GI of the tested sugars. Venous blood samples were used in study 2 to measure the concentrations of satiety hormones (peptide tyrosine, C-peptide, glucagon-like peptide-1, and leptin), TAC, plasma glucose, insulin, and glucagon concentrations at baseline (0min) and...
