Human clinical trial to assess the effect of consumption of multigrain Indian bread on glycemic regulation in type 2 diabetic participants.

The efficacy of multigrain flatbread in regulating the lipid profile and carbohydrate homeostasis among type 2 diabetic patients was studied in 100 type 2 diabetic participants. The results revealed that the anthropometric parameters remained unaltered in both test and control groups. The fasting blood glucose levels (140.70 ± 8.43 versus 132.89 ± 5.63 mg/dl) did not significantly decrease. In contrast, the insulin levels (12.96 ± 1.06 versus 10.83 ± 1.03 µIU/ml) and HbA1c levels (8.01 ± 0.27 versus 7.40 ± 0.21%) in the test group decreased significantly, and it was associated with a decrease in insulin resistance. The LDL levels in the test group decreased after the intervention (116.0 ± 5.67 versus 98.7 ± 5.68 mg/dl), while triglycerides and VLDL increased significantly and HDL levels remained unaltered. A significant decrease in average blood pressure (systolic/diastolic) was noticed among the test group participants. The human RBP4 and hs-CRP remained unaltered. PRACTICAL APPLICATIONS: Millets are rich in fibers, has complex carbohydrate, protein, and is lower in fat content. Millets provide a wide range of nutrients, phytochemicals, and are gluten-free with low glycemic nature. Their intake can reduce factors such as insulin resistance and oxidative stress responsible for the pathogenesis of type 2 diabetes and cardiovascular diseases. Our study indicated the use of multigrain flatbreads prepared from millets helped reduce serum insulin, LDL cholesterol, HbA1c levels, and incidentally blood pressure levels with a significant increase in insulin sensitivity in type 2 diabetes participants. The results suggest using the multigrain flatbread meal as a food supplement or meal replacer in diabetic participants in terms of glucose control and insulin sensitivity.

Accumulation of polychlorinated biphenyls in fish and assessment of dietary exposure: a study in Hyderabad City, India.

The objective of this study is to determine the concentrations of polychlorinated biphenyls (PCBs) in different fish species collected from fish outlets in the south Indian city of Hyderabad. The samples of fish extracted by using Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) and concentrations of polychlorinated biphenyls (PCBs, 45 congeners) were determined by gas chromatography-microelectron capture detection (GC-µECD) method. The intake of individual PCB congeners through fish, toxicity equivalence factors (TEFs), hazardous quotient, quantitative assessment, and risk evaluations was estimated in the Indian population. Daily dietary intakes of PCBs at the 95th-percentile-measured concentrations were twice the values of the 50th-percentile-measured concentrations in all socio-economic groups. The dietary intakes of PCBs through fish consumption in middle-income group, low-income group, and industrial laborers (0.023 µg kg(-1) day(-1)), the high-income group (0.031 µg kg(-1) day(-1)), and slum dwellers (0.039 µg kg(-1) day(-1)) exceeded the reference dose. The observed estimated daily intakes (EDIs) of our study for all socio-economic sections (0.0087 µg/kg/day) crossed the cancer benchmark concentration of 0.0003 µg/kg/day. In slum dwellers, the ingestion of fish from freshwater and marine water results in the highest lifetime cancer risks of 4.7 in 100,000 and 7.8 in 100,000, respectively. Ultimately, the concentrations of PCBs were determined high in all of the fish species collected. Risk assessment showed that the fish were highly contaminated with PCBs and may pose health threats to consumers in the city of Hyderabad as well as a lifetime cancer risk.

Effect of oxytocin injection to milching buffaloes on its content & stability in milk.

BACKGROUND & OBJECTIVES: Oxytocin (OT) injections to milch cattle for milk letdown have become a common practice amongst dairy farmers in India. Although there is no reported evidence, it is widely presumed that long term consumption of such milk leads to adverse health consequences. However, there is no information on the effect of exogenous OT injections on milk OT content and its stability during heating and gastrointestinal digestion. This study was carried out to determine the OT content in milk samples given by buffaloes with and without OT injections and to assess the stability of OT in the milk. METHODS: Milk samples from milch buffaloes (Murrah buffalo) were collected from local farmers with (n=121) or without (n=120) exogenous OT injections during 3 to 5 months of lactation period. The OT content of milk samples was estimated by competitive enzyme immunoassay (EIA). The thermal and digestive stability of OT was assessed by in silico and in vitro digestion methods. RESULTS: The OT content of the milk samples was similar regardless of OT injections used. Further, OT was found to be stable to heat treatment and gastric pepsin digestion while it was rapidly digested during the simulated intestinal digestion. Reduced OT was digested by pepsin, implying that internal disulphide bridge of OT rendered the peptide resistant to peptic digestion. On the other hand, phenylmethylsulphonyl fluoride (PMSF), a serine protease inhibitor, abrogated the pancreatin induced digestion of OT. INTERPRETATION & CONCLUSIONS: These findings suggest that exogenous OT injections do not influence its content in milk. Further, OT present in milk is rapidly degraded during intestinal digestion, ruling out its intestinal absorption and associated adverse health consequences, if any.

Assessment of dietary intakes of nineteen pesticide residues among five socioeconomic sections of Hyderabad--a total diet study approach.

Total diet study approach was used to assess the dietary intakes of pesticide residues among the select population in Hyderabad. When assessed by a food frequency questionnaire, it was found that the food intakes varied among five socioeconomic sections (SES). Therefore, we intended to compare the intakes of pesticide residues through these foods among the five SES. A total of 195 foods from different markets were collected and analyzed for 19 pesticides. The residues were analyzed with a gas chromatograph and were confirmed with mass spectrometry. About 51 % of the samples were detected with one or more residues. Thirteen out of the 19 residues were present in levels above detection limits in various concentrations. The median concentrations of the residues in all the samples tested, ranged from 0.00010 to 0.33 mg/kg. Highest median concentration was for ß-HCH in water samples. Exposures to all the residues were below the respective ADIs at both mean and 95th percentile levels of food intakes with highest estimated dietary intakes (EDIs) of ß-HCH in both the cases. The EDIs of ß-HCH were the highest among all the residues at both the intake levels among all the SES. The EDIs of ß-HCH were significantly higher in lower SES than higher SES possibly due to the consumption of rice cooked in water contaminated with ß-HCH. EDIs for other residues did not differ significantly among the five SES.
