Fastingbloodwasdrawnintravenouslyfromboththesubjects(nondiabetic and diabetic) after over night fasting before giving the control and experimental recipes. The post prandial blood samples were drawn after consumptionofcontrol/experimental recipe. Plasmaglucosewasestimatedby glucose-oxidaseperoxidasemethod. AUCwascalculatedusingthetrapezoidrule for each breakfast item. Glycemic response of the experimental recipe was determined. Theexperimental recipewherein 12.5 goffruitfiberincorporated showedasignificant(P<0.05)hypoglycemicresponseascomparedtothecontrol recipe.
