| dc.description | Epidemiological evidences suggest that consumption of white rice increases risk of developing metabolic syndrome and type 2 diabetes in Asians. In Malaysia, advanced cross-breeding programmes have yielded transgressive red rice variants with improved agronomic features and high antioxidant properties. This study evaluated the postprandial glucometabolic changes in response to rice consumption, which comprised of 3 transgressive red rice variants (UKMRC9, UKMRC10, UKMRC11) and 3 imported specialty rice varieties (Thai red, Basmati white, Jasmine white) benchmarked against a glucose standard (GLU). Twelve normoglycemic young adults (5 men/7 women; age, 23.2 ± 1.4 years; BMI, 22.1 ± 3.1 kg/m2; fasting plasma glucose, 5.02 ± 0.32 mmol/L; fasting plasma insulin, 6.17 ± 2.07 mU/L) completed this crossover design trial with six postprandial evaluations for 50 g carbohydrate equivalents of test rice and duplicate testing of GLU after an overnight fast. Venous blood was drawn fasted (0 min) and postprandially (15, 30, 45, 60, 90, 120 and 180 min). Glycaemic (GI) and insulin (II) indices were calculated from the 180 min incremental areas-under-the-curves for postprandial plasma glucose (IAUCglu) and insulin (IAUCins) by using the GLU as standard (=100). Measurements included HOMA index of postprandial insulin resistance (HOMA-PP), plasma lactate and neuropeptide hormones (motilin, neuropeptide-Y, orexin-A) concentrations. Repeated-measures ANOVA revealed that there were significant time x diet interactions for postprandial plasma glucose (p=0.025), insulin (p=0.007) and lactate (p<0.001) concentrations. Consumption of UKMRC9 and Basmati elicited significantly lower IAUCglu and IAUCins values (p<0.05) compared to GLU and Jasmine but not to other rice types (p>0.05). Jasmine had the highest GI (77 ± 7), followed by UKMRC11 (63 ± 9) > UKMRC10 (59 ± 9) > Thai Red (55 ± 9) > Basmati (50 ± 6) > UKMRC9 (46 ± 8). The lowest II was observed for UKMRC9 (51 ± 5), followed closely by Basmati (52 ± 5) < Thai red (59 v 4) < UKMRC11 (69 ± 6) ≡ UKMRC10 (69 ± 8) < Jasmine (76 ± 7). The GI, II and HOMA-PP scores of UKMRC9 and Basmati were significantly lower than that of Jasmine and GLU (p<0.05). GI values of test rice were negatively correlated with the crude protein (r = -0.357, p=0.002) and total dietary fibre (r = -0.237, p=0.047) content. Significant time x diet interaction effects were observed for postprandial plasma motilin (p=0.026), neuropeptide-Y (p=0.005) and orexin-A (p<0.001). However, these patterns were not significantly mediated by the GI and II characteristics of test rice. In summary, the UKMRC9 crossbred line together with Basmati elicited comparable and favourable metabolic responses compared to other rice types. The UKMRC9 and Basmati rice may serve as alternative cereal options for Malaysians. Randomised controlled trials are warranted to elucidate the effects of habitual consumption of low-GI, antioxidant-rich red rice on cardio-metabolic risks in people living with diabetes,Ijazah Sarjana Sains Kesihatan (Dietetik) | - |
