Abstract Background There exist controversies about the health effects of coconut. Fresh coconut consumption on human health has not been studied substantially. Fresh coconut consumption is a regular part of the diet for many people in tropical countries like India, and thus there is an increasing need to understand the effects of fresh coconut on various aspects of health. Aim To compare the effects of increased saturated fatty acid (SFA) and fiber intake, provided by fresh coconut, versus monounsaturated fatty acid (MUFA) and fiber intake, provided by a combination of groundnut oil and groundnuts, on anthropometry, serum insulin, glucose levels and blood pressure in healthy adults. Materials Eighty healthy volunteers, randomized into two groups, were provided with a standardized diet along with either 100 g fresh coconut or an equivalent amount of groundnuts and groundnut oil for a period of 90 days. Assessments such as anthropometric measurements, blood pressure, blood sugar and insulin levels were performed before and after the supplementation period. Results Results of this study showed a significant reduction in fasting blood sugar (FBS) in both the groups. However, a significant reduction in body weight was observed in the coconut group, while a significant increase in diastolic pressure was observed in the groundnut group. Conclusions Results of this study suggest that fresh coconut-added diet helps reduce blood glucose levels and body weight in normal healthy individuals.

Introduction: Cardiovascular disease is the number one cause of death globally with an incidence of adolescents and young adults in Indonesia as many as 153.705 cases. Central obesity is associated with the risk of cardiovascular disease due to increase in fasting blood glucose levels, cholesterol and triglyceride levels, and blood pressure. Aims: to determine the correlation between waist circumference and fasting blood glucose levels, triglyceride levels, and blood pressure in young adults. Method: This analytic study with a cross-sectional approach involved 53 young adult subjects (18-25 years old). Waist circumference is measured using a tape measure. Blood sugar and triglyceride levels were measured using Cobas® 6000 analyzer machine from blood samples of subjects after fasting for 8-12 hours. Blood pressure data are obtained by measurement using aneroid sphygmomanometer. Results: In this study, the mean waist circumference of the research subjects was 77,4 cm. No correlation was found between waist circumference and fasting blood sugar levels (p = 0,159). However, a positive correlation was found between waist circumference and triglyceride levels (p = 0,008; r = 0,332), between waist circumference and systolic blood pressure (p = 0,049; r = 0,230), and between waist circumference and diastolic blood pressure (p = 0,017; r = 0,293). Conclusion: waist circumference is positively correlated with triglyceride levels and blood pressure, but does not correlate with fasting blood sugar levels.

A single dose of reserpine (1 mg/kg body weight, injected subcutaneously) induced hyperglycaemia which persisted for at least 6 hours in rats kept in slings, but no significant alteration in the level of blood sugar was observed in free-running rats. The administration of a single dose of reserpine to unrestrained rats 3 hours prior to a test dose of insulin (0.5 units/kg body weight intramuscularly) or of tolbutamide (125 mg/kg per os) resulted in a decrease in the sensitivity of the animals to the hypoglycaemic action of these two compounds. Pretreatment with reserpine (1 mg/kg for 2 days) resulted in a failure of a single dose (0.5 mg/kg) of this compound to elevate blood glucose levels, in restrained rats, but such reserpine pretreated animals displayed a decreased hypoglycaemic response to a test dose of insulin.The hyperglycaemia observed in restrained rats following the injection of a single dose of reserpine was still observed in animals from which the pancreas had been completely removed, indicating that the change in blood glucose level in response to reserpine in these animals was not dependent on the presence of a pancreatic factor.

This study evaluated the lignan contents of raw omija (R) and sugared omija (S), byproducts discarded after the use of raw omija, by HPLC and determined their bioactivity by feeding rats R and S for eight weeks. S retained 63% more lignan than R. Body weight gains in the raw omija-fed group (RO) and sugared omija-fed group (SO) decreased significantly compared to that of the control group (CON, p < 0.05). Glucose and aspartate aminotransferase levels in the serum of the experimental groups were lower than those in CON, especially in SO (p < 0.05). The amount of atrial natriuretic peptide in RO decreased significantly compared to that in CON (p < 0.05). The renin activity in RO increased and that in SO decreased compared to the same in CON (p > 0.05). Therefore, it was suggested that sugared omija contains lignan compounds and potentially contributes to bioactivity in that it decreases blood glucose levels and blood pressure.

Introduction: Nonalcoholic fatty liver (NAFLD) occurs in a setting of high fat diets, insulin resistance, obesity and dyslipidemia. Individuals with NAFLD have an increased risk of developing metabolic syndrome. Heme oxygenase-1 (HMOX1), a major cytoprotective enzyme, attenuates oxidative stress and obesity and increases insulin sensitivity. The antioxidant effect of HMOX1 is due to an increase in ferritin, and bilirubin and a decrease in heme, a pro-oxidant. The aim of this study was to examine the role of increased hepatic HMOX activity in decreasing steatosis, adiposity and vascular dysfunction and to determine the mechanism underlying these metabolic changes in obese mice. Methods: Obese mice were administered cobalt protoporphyrin (CoPP) and HMOX activity inhibitor stannous mesoporphyrin (SnMP) for 6 weeks. Blood pressure, body weight and blood glucose levels were measured in all the groups. Glycogen content, hepatic fibrosis, heme levels, fatty acid synthase (FAS) and lipid droplet size in liver were also assessed. Results: CoPP administration increased hepatic HMOX1 protein levels and HMOX activity, decreased blood pressure, body weight, blood glucose levels, hepatic heme content (p<0.05) as compared to obese mice. Our results also showed that HMOX1 induction causes a significant decrease in lipid steatosis ( lipid droplet size and FAS levels; p<0.01) as compared to obese mice. Densitometry analysis showed increased expression of PPARα and Glut 1 along with decreased expression of PGC1α in hepatic tissue. These beneficial effects were reversed by administration of SnMP. Conclusion: This novel study demonstrates the role of hepatic HMOX1 in attenuating the fatty liver and metabolic homeostasis by decreasing PGC1α and heme content and enhancing glycogen levels. Pharmacological agents that increase HMOX1 levels or gene targeting of HMOX1 offer a promising therapeutic target for NAFLD and suggest the existence of a significant link between the heme-HMOX system and the extent and severity of heme-dependent fatty liver.

Background: Type 2 diabetes mellitus (T2DM) is a highly prevalent disease characterized by chronic hyperglycemia. Yoga is a form of mind-body intervention shown to have a positive impact on several health conditions in both healthy and diseased patients. The present study is intended to assess the effects of the Residential Integrated Yoga Program (RIYP) on blood glucose levels in patients with T2DM. Material and Methods: Data of 598 (186 females) T2DM patients from a holistic health center in Bengaluru, India, who attended a 15-day RIYP between January 2013 and December 2015 was obtained retrospectively. Average age of the participants was 56.45 ± 11.02 years. All subjects underwent a 15-day RIYP which involved yoga-based lifestyle changes with components of regulated sleep, balanced diet, asanas, pranayama, relaxation techniques, meditations, yogic cleaning procedures, and tuning to the nature. Fasting and post-prandial blood sugar, medication score, symptom score, systolic and diastolic blood pressure, pulse rate, and respiratory rate were assessed before and after intervention. Result: There was a significant decrease in fasting (p < 0.001) and post-prandial blood sugar levels (p < 0.001) along with a significant reduction in medication and symptom scores after 15 days of RIYP compared to baseline. Conclusion: The present study indicates that 2 weeks of a yoga-based residential program improves blood glucose levels, blood pressure, and medication score in patients with T2DM. However, further randomized controlled studies need to be performed in order to confirm the present findings.

Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Abstract Background Ethnobotany knowledge in a community has shaped local wisdom in utilizing plants to treat diseases, such as the use of Malaka (Phyllanthus emblica) flesh to treat type 2 diabetes. This study presented evidence that the phenolic extract of the Malaka flesh could reduce blood sugar levels in the diabetic induced rats. Methods The phenolic extract of the P. emblica was administrated to the glucose-induced rats of the Wistar strain Rattus norvegicus for 14 days of treatment where the Metformin was used as a positive control. The data generated were analyzed by the two-way ANOVA Software related to the blood glucose level and by SAS Software related to the histopathological studies at a significant 95% confidence. Results The phenolic extract with concentrations of 100 and 200 mg/kg body weight could reduce blood glucose levels in diabetic rats. The post hoc Dunnet test showed that the administration of the extract to the rats with a concentration of 100 mg/kg body weight demonstrated a very significant decrease in blood glucose levels and repaired damaged cells better than administering the extract at a concentration of 200 mg/kg weight body. Conclusion The evidence indicated that the phenolic extract of the Malaka flesh can be utilized as anti type 2 Diabetes mellitus without damaging other organs.

In recent years, many authors have investigated the possible antidiabetic effect of lactic acid bacteria. Lactobacillus species constitute a major part of the lactic acid bacteria group and have been found to exhibit beneficial effects on the development of diabetes and its complications. In the current study, we investigated the effects of newly characterised Bulgarian Lactobacillus strains, Lactobacillus brevis 15 and Lactobacillus plantarum 13, on blood glucose levels and body weight of rats fed a fructose-enriched diet. An experiment was conducted over a period of 8 weeks with 24 2-month-old Wistar rats randomly assigned to receive a standard diet (Con, control group), fructose-enriched diet (Fr group), standard diet with probiotics given twice a week (Pro group), and fructose-enriched diet with probiotics given twice a week (Pro+Fr group). At the end of the experimental period, a statistically significant increase in body weight was observed in all experimental groups (P<0.0001). The highest rise was seen in the fructose group (Fr, 169±19 g), followed by the Pro+Fr group (153±15 g), Pro group (149±13 g), and Con group (141±5 g). Moreover, the final blood glucose levels had risen significantly in the groups receiving fructose either without (Fr; P<0.0001) or with lactobacilli (Pro+Fr; P=0.002), while the rise was insignificant in the group of rats given probiotic supplementation only (Pro, P=0.071) and inexistent in the Con group (P=0.999). The highest elevation of blood glucose levels was observed in the Fr group (3.18 mmol/l), followed by the Pro+Fr group (2.00 mmol/l) whereas the Pro group showed the lowest levels (0.60 mmol/l). The results of our study suggest that the newly characterised Bulgarian Lactobacillus strains, L. brevis 15 and L. plantarum 13, could be considered as possible probiotics and might be able to prevent some metabolic disturbances.
