摘      要：The estimation of glycemic index(GI) of rice-based mixed meal either by using predicted GI(GI_(pred)) or adjusted GI(GI_(adj)) formula is *** study aimed to determine the glycemic response of rice in rice alone or mixed meals and to identify the appropriate formula for estimating the GI of rice-based mixed *** glycemic responses produced by the rice alone(red rice,fragrant white rice or parboiled rice) and the rice-based mixed meals(fried red rice,fried fragrant white rice or fried parboiled rice) which provided 25 g available carbohydrate were assessed in 11 healthy *** determine the measured GI(GImeasured) of rice alone and rice-based mixed meals,participants underwent three repeated tests of a reference food(Glucolin~?).Tests were performed in random order on nine separate visits after an overnight fasting for at least 8 *** glucose at baseline(0 min),15,30,45,60,90 and 120 min from starting the meals was assessed and used to determine the incremental area under the curve(iAUC_(120)).The agreement between GImeasured and the estimation formulae(GI_(pred) or GI_(adj)) were determined using Bland-Altman *** iAUC_(120) after consuming rice alone was significantly higher than the rice-based mixed meals except for fried fragrant rice,which was comparable to the rice alone(P 0.05).The GI_(measured) values of rice were categorized as medium(61 for parboiled rice,67 for fragrant white rice,and 68 for red rice).GI_(pred)(r = 0.40,P 0.01) and GI_(adj)(r = 0.41,P 0.01) were significantly correlated with iAUC_(120).The agreement between GI_(measured) and GI_(adj) is apparent suggesting the usefulness of GI_(adj) in estimating meal GI of rice-based mixed meals.
