The interest in barley as a food is increasing worldwide because of its high dietary fibre (DF) content and low glycaemic index (GI). DF in cereals may prove beneficial in improving blood glucose response in the long term. However, a dose-dependent effect of insoluble fibre on reducing postprandial blood glucose levels is yet to be proven. The objective of the present study was to determine the glycaemic response to two barley porridges prepared from whole barley grains varying in fibre content. In two separate non-blind randomised crossover trials, ten human subjects consumed barley porridge with 16 g/100 g and 10 g/100 g fibre content provided in different serving sizes (equivalent to 25 and 50 g available carbohydrate). The glycaemic response to both barley porridges was significantly lower than the reference glucose (P < 0·05). There was no significant difference between the glucose areas under the curve or GI for the two barley porridges. We concluded that irrespective of the difference in total fibre content or serving size of barley porridges, their GI values did not differ significantly.

Abstract The hypothesis that coarse grain particles in breads reduce glycaemic response only if the particles remain intact during ingestion was tested. Three breads were formulated: (1) White bread (WB - reference), (2) 75% of kibbled purple wheat in 25% white bread matrix (PB), (3) a 1:1 mixture of 37.5% kibbled soy beans and 37.5% of kibble purple wheat in 25% white bread matrix (SPB). Each bread was ingested in three forms: unchewed (U), as customarily consumed (C), and homogenized (H). Twelve participants ingested 40 g available carbohydrate portions of each bread in each form, with post prandial blood glucose measured over 120 min. Glycaemic responses to WB were the same regardless of its form when ingested. Unchewed PB had significantly less glycaemic effect than WB, whereas the C and H forms were similar to WB. Based on a glycaemic index (GI) of 70 for WB the GI values for the C, U and H breads respectively were WB: 70.0, 70, 70, PB: 75, 42, 61, SPB: 57, 48, 55 (%) (Least significant difference = 17.43, p <0.05, bold numbers significantly different from WB). The similar glycaemic response to the H and C forms of the breads, and their difference from the U form, showed that the glycaemia-moderating effect of grain structure on starch digestion was lost during customary ingestion of bread. We conclude that kibbled grain structure may not effectively retard starch digestion in breads as normally consumed because it is largely eliminated by ingestive processes including chewing.

Objective: Diabetes mellitus is a leading cause of death and disability in the world and its prevalence is predicted to rise to 10% by 2030. Hence, this study is conducted with objectives to find out the effect of aerobic exercises and resisted exercises on blood glucose levels in type 2 diabetes mellitus (T2DM) subjects and to compare the effect of both exercises on blood glucose level.Method: The comparative study was conducted at Krishna Institute of Medical Sciences Deemed University, Physiotherapy department, Karad. 30 participants with age group between 30 and 65 years were taken. Subjects were selected as per inclusion and exclusion criteria. Group A (15) participants were given aerobic exercise on static bicycle, and Group B (15) participants were given resistance training using dumbbells and weight cuffs for 5 days/week for 4 weeks. Diet recommendations were given to every participant.Results: Statistical analysis was performed using paired and unpaired t-test. Analysis showed statistically extremely significant difference in fasting blood glucose level and postprandial blood glucose level in both the groups (p≤0.0001).Conclusion: Thus, this study concludes that both aerobic exercises and resistance training prove to be beneficial in controlling blood glucose levels in T2DM subjects.

Three dietary fibres with different physicochemical properties were studied in healthy humans for their effects on small intestinal motility and postprandial hyperglycaemia. Duodeno-jejunal motor activity was evaluated electromyographically for 180 min in six subjects who had ingested a test meal composed of glucose alone or glucose with 15 g of wheat bran (WB), sugar beet (SB) or ispaghula (I) fibres. Glucose and insulin concentrations were determined during the same period. Each subject received each of the four test meals randomly during a 4 d period. Addition of SB or I to the glucose meal altered duodeno-jejunal motility. Both of these fibres inhibited stationary contractile activity and increased the propagation length and velocity of propagated activity, whereas addition of WB had no effect. These results could reflect the high water-holding capacity of SB and 1. Blood glycaemic response to the glucose meal was reduced by SB and I but remained unchanged with WB. Postprandial blood glucose levels were significantly correlated with the total motility index (r 0·82) and stationary activity (r 0·79). Taken together, these observations suggest that the contractile activity induced by dietary fibre in the small intestine probably plays a major role in delayed glucose absorption.

1. The degree to which disruption by mastication affects the glycaemic response to four different carbohydrate foods was investigated in healthy human volunteers; each food was eaten by six subjects.2. Subjects ate meals of sweetcorn, white rice, diced apple or potato on two occasions; on one occasion they chewed the food thoroughly, on the other occasion they swallowed each mouthful without chewing it.3. When the foods were chewed the postprandial blood glucose levels rose to levels which vaned according to the food ingested.4. Swallowing without chewing reduced the glycaemic response to each food, achieving a similar effect as administration of viscous polysaccharides or ‘slow-release’ carbohydrates.

AbstractKiwifruit is a carbohydrate food of low glycaemic potency which could potentially be exchanged for starch-based foods in management of postprandial glycaemia. The effect of equicarbohydrate partial exchange of kiwifruit varieties ‘Hayward’ green (GR) and ‘Zesy002’ (SunGold; SG) for a starchy wheat-based breakfast cereal (WB) on the characteristics of the postprandial glycaemic response and satiety was therefore determined. A total of twenty non-diabetic subjects (mean age 36 years; mean BMI 24·5 kg/m2) consumed four meals, each containing 40 g available carbohydrate, in random order, after an overnight fast. The meals were: (1) glucose; (2) 70·29 g breakfast cereal; (3) 200 g of GR plus breakfast cereal (30·93 g); and (4) 200 g of SG plus breakfast cereal (27·06 g). Throughout the 180 min postprandial period, capillary blood glucose concentrations were monitored, and satiety rated by a visual analogue scale. Partial kiwifruit substitution of WB significantly reduced postprandial glycaemic response amplitude (glucose, 3·91; WB, 3·66; WB + GR, 2·36; WB + SG, 2·31  mmol/l; least significant difference (LSD) 0·64; P < 0·001) and incremental area under the blood glucose response curve (0–120 min) (glucose, 228; WB, 180; WB + GR, 133; WB + SG, 134 mmol/l × min; LSD 22·7; P < 0·001). The area between baseline and response remained positive in kiwifruit-substituted meals but became negative after 120 min with glucose and WB, indicating that kiwifruit improved homeostatic control. Kiwifruit substitution of cereal did not significantly reduce satiety. We conclude that either ‘Hayward’ or ‘Zesy002’ kiwifruit may be used in equicarbohydrate partial substitution of starchy staple foods to reduce glycaemic response and improve glucose homeostasis without decreasing satiety.

Diet And Lifestyle

Many studies conducted in recent years have shown that the incidence of cancer is still on the rise. According to the World Health Orgnization (WHO), most of these cases are a consequence of poor diet and lifestyle. Excess dietary carbohydrates, low-glycaemic index carbohydrates in particular, and low intake of fibre promote carcinogenesis. Many studies led to a conclusion that high body mass index (BMI) and waist to hip ratio (WHR) contribute to the risk of cancer. High blood glucose levels are one of the main factors predisposing to cancer. High postprandial blood glucose, which is most commonly observed in patients with type 2 diabetes, is also one of the factors that disturb metabolic transformations, which may promote carcinogenesis. It is worth following the principles of rational nutrition as part of cancer prevention. Manufacturers meet consumers' demands by developing improved food products, such as jams made from vegetables, which are higher in fibre and lower in sugar compared to fruit jams.

Abstract The beneficial effects of dietary fiber on sows performance have been widely studied, but it’s still unclear how fermentable fiber affects sows glucose metabolism and reproduction. The present study aimed to investigate the effects of late gestational inulin supplementation on sows pre-farrowing glucose metabolism and reproductive performance. A total of 106 sows were allotted randomly to 2 groups, receiving either a control diet with 4% wheat flour, or a diet with 4% inulin, from gestation day 85 to 110, both diets met nutrient requirements expressed by NRC. On day 111, sows blood glucose was tested before a common lactation diet meal, then subsequent glucose levels were measured at 1, 2 and 3 hour after meal. Sows were weighed on initial, entry and weaning days. The numbers of live-born and stillborn piglets as well as mortality were recorded. Inulin supplementation didn’t affect sows average daily intake during lactation, and also no significant difference was observed in weaning bodyweight and backfat thickness between two groups. However, the relative wean to entry BW loss was significantly lower in inulin fed sows than control (11.3% vs 13.5%) (P&lt; 0.05). Moreover, postprandial glucose response was less steep in inulin group compared with control, especially glucose concentration at 1h after meal was 10.2% higher in the control group sows. Although the sows farrowing duration was similar in two groups, inulin significantly increased (P&lt; 0.05) proportion of born alive from 90.1% to 93.0% and reduced (P=0.10) still born from 7.3% to 5.4%. Post-foster mortality and livability did not differ between treatments, litter birth weight and average birth weight were not different either. In conclusion, Sows fed 4% inulin diet at late gestation tended to have lower weight loss, slower rate of postprandial blood glucose response and higher born alive and lower stillborn.

Background: Obesity cause various physiological changes in the body, one of which is insulin resistance causes high blood glucose levels. Chewing is a stimulus of cephalic phase responses and sensory stimulation that can increase hormones releasing such as insulin, ghrelin, cholecystokinin (CCK) and glucagon like peptide-1 (GLP-1). Chewing plays important role in determining postprandial plasma glucose concentration.Objective: Investigate the effect of chewing on postprandial blood glucose in obese adults.Method: This was true experimental research. Research subjects were treated in the form of chewing 22 times and 40 times each mouthful. Blood glucose levels were measured using glucometer on fasting blood glucose and postprandial blood glucose 15 minutes, 30 minutes, 60 minutes, and 120 minutes. Statistical test using Independent t-test.Results: The mean postprandial glucose levels in the 22 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 112.11 ± 14.3328, 126.11 ± 15.667, 116.94 ± 15.539, and 89.67 ± 11.668 . While the mean postprandial blood glucose levels in the 40 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 122.22 ± 14.381, 129.61 ± 15.112, 109.50 ± 14.995, and 85.83 ± 13.963. There were statistically significant differences between chewing groups 22 times and chewing 40 times on fasting blood glucose and 15 minutes postprandial blood glucose (p = 0.041 and p = 0.042), while on 30 minutes postprandial glucose testing, 60 minutes , and 120 minutes there was no significant difference (p> 0.05).Conclusion: There was significant differences in 15 minutes postprandial blood glucose level between group 22 times chewing and 40 times chewing each mouthful.
