Aims: Diabetes rates are especially high in China. Risk of Type 2 diabetes increases with high intakes of white rice, a staple food of Chinese people. Ethnic differences in postprandial glycaemia have been reported. We compared glycaemic responses to glucose and five rice varieties in people of European and Chinese ethnicity and examined possible determinants of ethnic differences in postprandial glycaemia. Methods: Self-identified Chinese (n = 32) and European (n = 31) healthy volunteers attended on eight occasions for studies following ingestion of glucose and jasmine, basmati, brown, Doongara® and parboiled rice. In addition to measuring glycaemic response, we investigated physical activity levels, extent of chewing of rice and salivary α-amylase activity to determine whether these measures explained any differences in postprandial glycaemia. Results: Glycaemic response, measured by incremental area under the glucose curve, was over 60% greater for the five rice varieties (P < 0.001) and 39% greater for glucose (P < 0.004) amongst Chinese compared with Europeans. The calculated glycaemic index was approximately 20% greater for rice varieties other than basmati (P = 0.01 to 0.05). Ethnicity [adjusted risk ratio 1.4 (1.2-1.8) P < 0.001] and rice variety were the only important determinants of incremental area under the glucose curve. Conclusions: Glycaemic responses following ingestion of glucose and several rice varieties are appreciably greater in Chinese compared with Europeans, suggesting the need to review recommendations regarding dietary carbohydrate amongst rice-eating populations at high risk of diabetes. © 2012 Diabetes UK.

AbstractIncreasing trends in the occurrence of diabetes underline the need to develop low glycemic index (GI) rice with preferred grain quality. In the current study, a diverse set of 3 K sub-panel of rice consisting of 150 accessions was evaluated for resistant starch and predicted glycemic index, including nine other quality traits under transplanted situation. Significant variations were noticed among the accessions for the traits evaluated. Trait associations had shown that amylose content possess significant positive and negative association with resistant starch and predicted glycemic index. Genome-wide association studies with 500 K SNPs based on MLM model resulted in a total of 41 marker-trait associations (MTAs), which were further confirmed and validated with mrMLM multi-locus model. We have also determined the allelic effect of identified MTAs for 11 targeted traits and found favorable SNPs for 8 traits. A total of 11 genes were selected for haplo-pheno analysis to identify the superior haplotypes for the target traits where haplotypes ranges from 2 (Os10g0469000-GC) to 15 (Os06g18720-AC). Superior haplotypes for RS and PGI, the candidate gene Os06g11100 (H4-3.28% for high RS) and Os08g12590 (H13-62.52 as intermediate PGI). The identified superior donors possessing superior haplotype combinations may be utilized in Haplotype-based breeding to developing next-generation tailor-made high quality healthier rice varieties suiting consumer preference and market demand.

Pulses are low-glycaemic foods rich in protein (20–25 %), resistant starch and fibre that suppress appetite and glycaemia. The objective of the present study was to elucidate the component(s) of yellow peas responsible for these benefits and assess their efficacy as value-added food ingredients. We investigated the effects of 10 or 20 g of isolated yellow pea protein (P10 and P20) or fibre (F10 and F20) on food intake (FI) at an ad libitum pizza meal served at 30 min (Expt 1, n 19) or 120 min (Expt 2, n 20) and blood glucose (BG) and appetite in young, healthy males (20–30 years). In Expt 1, P20 led to lower FI than control (4937 (sem 502) v. 5632 (sem 464) kJ (1180 (sem 120) v. 1346 (sem 111) kcal)) and all other treatments (P < 0·01) and lower cumulative FI (pizza meal kcal+treatment kcal; CFI) compared to F10 (5460 (sem 498) v. 6084 (sem 452) kJ (1305 (sem 119) v. 1454 (sem 108) kcal); P = 0·033). Both protein treatments suppressed mean pre-meal (0–30 min) BG compared to control (P < 0·05), whereas only P20 suppressed mean post-meal (50–120 min) BG (P < 0·01). There was no effect of treatment on pre-meal or post-meal appetite. In Expt 2, there was no effect of treatment on FI, CFI, or pre- or post-meal BG or appetite. In conclusion, protein is the component responsible for the short-term effects of yellow peas in the regulation of glycaemia and FI, but its second-meal effects disappear by 2 h post-consumption.

Carbohydrate Components

Staple diet patterns such as white rice consumption play an important part in the occurrence of chronic lifestyle-related disease like diabetes. This study intended to identify pigmented rice cultivars from India as an alternative to white rice. Nine carbohydrate components were quantified in six red and two black pigmented rice varieties. In vitro starch digestibility was also analyzed and the predicted glycemic index (pGI) was estimated. The relationship between the carbohydrate components and the pGI of the rice varieties was analyzed. The rice varieties, Kattuyanam and Chennangi exhibited high levels of insoluble dietary fibre, total dietary fibre and amylose. High soluble dietary fibre contents were observed in Poonghar and Aruvadam kuruvai. The levels of resistant starch and slowly digestible starch were found to be the highest in Karupakavuni. The results indicated Kattuyanam, Chennangi, Karungkuruvai, and Poonghar to be low pGI rice varieties (< 55). The three varieties, Kesari, Karupakavuni, and Aruvadam kuruvai were categorized under the medium pGI category (56-69). Mapillai samba had a high pGI of 70 which could be due to processing (partially milled and parboiled), but had significantly lower pGI than the white rice, Sona masuri (GI – 76). The dietary fibre components, resistant starch, slowly digestible starch, and the amylose content were negatively correlated with the pGI. Among these components, the insoluble dietary fibre, total dietary fibre, and resistant starch with significantly high (p ≤0.01) correlation were found to be the major determining factors of pGI in the studied pigmented rice cultivars. The inclusion of the identified pigmented rice varieties with low to medium glycemic response in the diet could become a key role in the dietary management of diabetes, especially among the rice-eating population.
