Abstract
In vitro anti-diabetic eff ect of diff erent vegetables has been reported; however, the same role of these vegetables has not
been much explored through human intervention. Th erefore, present study was conducted to examine the comparative
effects of muffi ns supplemented with bitter gourd (BGM) and other vegetables like spinach (SPM) and eggplant (EPM) on
subjective appetite, Blood Glucose (BG), gut hormones and food intake in healthy young males through a randomized, cross
over experiment. Aft er 12 hours fasting, 24 healthy young males (18-30 years) were fed 300 g of plain muffi ns (control) or
supplemented with bitter gourd powder, BGM (10 g/100 g fl our), or spinach powder, SPM (10 g/100 g fl our), or eggplant
powder, EPM (10 g/100 g fl our). An ad libitum pizza meal was served at 120 minutes to measure the food intake. Subjective
appetite, blood glucose and gut hormones (insulin, GLP-1, active ghrelin) were measured at intervals from baseline to 120
minutes. Post-treatment (0-120 minutes) glucose, but not insulin, decreased following all the vegetables supplemented muffi ns
compared to the control (P<0.0001) with more pronounced eff ect of BGM. However, post-treatment average subjective appetite(P=0.0017) and food intake (P=0.0021) were reduced following BGM but not SPM and EPM. BGM further improved GLP-1 concentration (P<0.0001) and reduced active ghrelin (P=0.0022), compared with control. Th e bitter gourd supplemented baked foods possess potential more than other vegetables to regulate postprandial appetite and glycemic responses, without disproportionate increase in insulin concentration.
