Abstract
Spikes in blood glucose (BG) result in adverse health consequences in people with and without diabetes. This study aimed to compare the BG and satiety responses of adding mango or sugar to a high glycemic load (HGL) breakfast. A randomized, controlled trial (cross-over design) was conducted with 18 participants. Participants consumed cornflakes and almond milk (Control), control plus 34gm added sugar (ASug), or added mango (AMango) with 34gm carbohydrate. BG was determined at fasting, 15, 30, 60, 90, 120min postprandial; satiety was rated with a visual analog scale at each time point. At 120min, subjects consumed a snack of hummus and crackers ad libitum. Repeated measures ANOVA was used to determine differences in BG spike, iAUC, satiety, and caloric intake of the snack. The BG spike was significantly higher in the ASug vs the Control (P=0.014); there was no difference in the spike between the AMango and Control. The glucose AUC was significantly higher in the ASug and AMango group than the control (P< 0.002). There were no differences in kcals of the snack consumed. At 15, 30, 60, and 120min postprandial, satiety was rated significantly higher in the AMango group vs the Control and ASug groups (P< 0.05). Adding mango to a HGL breakfast may result in beneficial BG and satiety responses. Although added mango increased satiety, there was no compensation for the added kcals at the snack. Further research is needed to determine if added kcals are compensated throughout an entire day.
