Abstract

Background: Urtica dioica, or the stinging nettle, is recommended by ancient medical texts for the treatment of high blood sugar.
Methods: We set up a perifusion system, in which an exact number of islets of Langerhans were exposed to an active component of the leaf extract of Urtica dioica, obtained by TLC. The active component was then injected into the peritoneum of both normal and diabetic rats to evaluate response in vivo.
Results: There was a marked increase in insulin secretion in vitro, as determined by ELISA. In vivo, there was an increase in blood insulin content following intraperitoneal injection. The increase in serum insulin observed at 60 minutes was associated with a decrease in blood glucose, checked several times during the observation period. Maximum insulin release over 120 minutes was equal to five times the baseline value. The decrease in blood sugar correlated with both the timing and magnitude of insulin release.
Conclusion: Notwithstanding the magnitude of the changes observed, the results obtained in normal and diabetic rats were similar.

Abstract

Background: Studies of the metabolic effects of Ramadan fasting on patients with type 2 diabetes mellitus are inconclusive.
Methods: Fifty-seven volunteers with type 2 diabetes underwent anthropometric and biochemical evaluation before and on the 14th and 28th days of Ramadan. Biochemical markers were measured by standard laboratory methods. Anthropometric measurements followed WHO criteria. Statistical analysis was by ANOVA for repeated measurements and Friedman’s two-way ANOVA, using SPSSv6 software.
Results: Daily cholesterol intake increased in all subjects (p<0.03). Body mass index increased (p<0.03) in women, but body mass index (BMI) and waist-to-hip ratio both decreased (p<0.01) in men. Blood pressure, fasting blood glucose and serum fructosamine did not change during the study. Plasma insulin (p<0.05), C-peptide (p<0.01) and insulin resistance (p<0.01) decreased only in men. Total and LDL cholesterol increased significantly in all subjects during the study.
Conclusion: Ramadan fasting does not alter carbohydrate metabolism or tissue insulin sensitivity in type 2 diabetes patients, given appropriate dietary education and rescheduling of oral hypoglycaemic medication. Lipid profile is unfavourably altered due to changes in both diet and biochemical response to starvation. Anthropometric indices improve in men but not women, possibly because of reduced physical activity in the latter.

Abstract

Introduction: In patients with type 2 diabetes, triglyceride (TG) is usually increased, HDL decreased, and LDL normal. This pattern is associated with an increased risk of coronary heart disease. More recently, dense-particle LDL has been identified as an important risk factor for coronary heart disease.
Methods: 298 patients with type 2 diabetes attending the diabetes clinic at Doctor Shariati University Hospital underwent anthropometric and biochemical assessment. Anthropometric measurements followed WHO criteria. Biochemical indices (apoB100, TG, cholesterol, LDL, LDL particle size, HDL, and apoA1) were measured using standard laboratory methods. One-way ANOVA was used to analyse data with SPSSv6 software.
Results: Mean patient age was 55±13.2 years. Mean duration of diabetes was 9.5±6.1 years. The majority of patients were moderate to severely overweight. 73.2% of patients had some form of hyperlipidaemia. 20.7% had isolated hypertriglyceridaemia, 21% isolated hypercholesterolaemia, and 31.5% mixed hyperlipidaemia. Mean apoA1 concentration was higher than normal in this group, and mean apoB100 concentration lower. LDL particle size generally followed a small and dense pattern.
Conclusion: This study shows that LDL particles in both men and women with type 2 diabetes undergo both qualitative and quantitative changes. 35.5% of patients had smaller, denser LDL particles than normal. It appears that dyslipidaemia and B-pattern LDL particles are important risk factors for atherosclerosis in this group.

Abstract

Objective: To compare the effect on insulin absorption intra-nasally of Acanthophyllum squarrosum (ASQ) compared with Acanthophyllum saponaria (ASA) and sodium cholate (NAC), which have proven pro-absorptive effects.
Methods: The formulation used in this study contained 2IU insulin (per rat), 1% carboxymethylcellulose (CMC) and a pro-absorptive agent at the same concentration. We assessed the hypoglycaemic effect of each formulation in 5 rats in the fasting state.
Results: There was no significant difference in the pro-absorptive effects of ASQ, ASA, and NAC. Blood glucose levels 2 hours after administration of insulin, given as a percentage of baseline glucose concentration, were as follows for the three formulations used: ASQ: 36.78±11.06%, ASA: 27.46±2.39%, and NAC: 39.94±14.93%. Conclusion: Acanthophyllum squarrosum has a significant pro-absorptive effect, comparable to that to Acanthophyllum saponaria.

Abstract

Background: Cardiac X Syndrome is the occurrence of angina pectoris in spite of a normal coronary angiogram, probably due to a disorder of the cardiac sensory nervous system (pain perception). The insulin resistance (metabolic X) syndrome is an important determinant of coronary artery disease. There is a dearth of research on the association between insulin resistance and cardiac X syndrome. We compared the hormonal status of three groups of postmenopausal women: those with cardiac X syndrome, those with coronary artery disease, and healthy controls.
Methods: 149 postmenopausal women (age range 48-58 years), matched for duration of menopause, were recruited for this study. Gonadotrophin and fasting insulin levels as well as blood pressure and body mass index were measured in all three groups.
Results: LH, FSH, oestradiol and progesterone levels were similar in all three groups. Women in the first two groups (that is, those with angina pectoris regardless of the result of coronary angiography) had a significantly higher BMI than controls. Fasting insulin levels were significantly higher in the first two groups compared with controls (p<0.01). There was no difference in fasting insulin level between the normal and abnormal angiography groups. There was no significant correlation between fasting insulin and any of the other variables, even though the association between fasting insulin and BMI in the abnormal angiography-confirmed CAD group very nearly approached statistical significance (p=0.059).
Conclusion: Women with angina pectoris, regardless of the outcome of coronary angiography, have hyperinsulinism and a higher BMI than controls. It seems that hyperinsulinism is the fundamental mechanism by which both the cardiac X and metabolic X syndromes occur. Further research is needed to elucidate this matter.

Abstract

Background: Diabetes type 1 is characterized by autoimmune destruction or primary dysfunction of pancreatic  cells. The more common form is the autoimmune type, which can be associated with other endocrine malfunction such as adrenal insufficiency and Hashimoto’s thyroiditis. Autoimmune thyroiditis is characterized by presence of anti TG, anti TPO and anti TSH antibodies in the plasma. This study has investigated the prevalence of autoimmune thyroid disorders in type 1 diabetic patients.
Methods: 200 type 1 diabetics and 200 age/sex matched non-diabetic controls were recruited. Blood samples were taken to determine serum levels of thyroid hormones (T3RU, T3, T4, and TSH) and antithyroid antibodies.
Results: TG-Ab and TPO-Ab levels were significantly higher (P<0.001) in diabetics compared to controls (mean TG-Ab: 955.7±495.5 in diabetics and 451.0±189.5 in controls mean TPO-Ab: 463.2±182.3 in diabetics and 112.4±38.3 in controls). Clinical and subclinical hyperthyroidism was four times more common in diabetics. Conclusion: It seems reasonable that type 1 diabetic patients, especially those at younger ages, be screened for thyroid hormones and anti-thyroid antibodies

Abstract

Celiac disease and typel diabetes mellirus have been linked to the same HLA markers and chromosomal loci, which may account for the concurrence of the two disorders in a significant number of patients. This study was designed to investigate the frequency of anti-gliadin antibodies, a marker for celiac disease, in diabetic patients.
Methods: In this study, 182 diabetic patients (52 with typel and 130 with type2 diabetes) were screened for anti-gliadin IgG by indirect immunofluorescence. Age range was 3-29.5 and 42-65 years for type 1 and type 2 diabetes groups.
Results: Anti-gliadin IgG was found in 1.9% and 1.5% of patients with type land type 2 diabetes. In Tehran, 0.02% of healthy blood donors have been reported to be seropositivitive for anti-gliadin IgG.
Conclusion: The prevalence of anti-gliadin seropositivity in type 1 and type 2 diabetics, was respectively 30 and 24 times higher than the general population of Tehran. This concurs with other reports indicating higher occurrence of celiac disease in diabetic populations. The rather low sensitivity and specificity (both around 80%) of the antigliadin antibody test has made it a suboptimal diagnostic test. However, it is quick and inexpensive and can be suitable for screening programs. We recommend the test in all at-risk populations including diabetics.

Abstract

Background: Although dietary guidelines recommend increased intake of grain products to prevent chronic diseases, epidemiologic data regarding whole-grain intake associated with metabolic syndrome is sparse. This study was undertaken to evaluate the relationship between whole-grain intake, metabolic syndrome and metabolic risk factors in Tehran adults population.
Methods: In this cross-sectional study, 827 subjects aged 18-74 were randomly selected from participants of the Tehran Lipid and Glucose Study. Usual dietary intake was assessed using a semi-quantitative food frequency questionnaire and two 24-hour dietary recalls. BMI, FBS, blood pressure, hypertriglyceridemia, hypercholesterolemia, high LDL, low LDL, metabolic syndrome (according to ATP III guidelines) and hypertension (based on JNC VI) were assessed subjects were categorized on quartile cut-points of whole and refined grain intake.
Results: Mean (±SD) consumptions of whole- and refined grains were 93±29 and 201±57 g/d, respectively. Compared with subjects in the lower quartile category, those in the upper category of whole-grain intake had lower prevalence of metabolic risks. Conversely, those in the higher category of refined grain intake had higher prevalence of metabolic risk factors, except for diabetes. After controlling for confounders, a significant decreasing trend was observed for the risk of having hypertriglyceridemia [odds ratios among quartiles: 1.00,0.89, 0.74, 0.61, respectively], hypertension and metabolic syndrome. Higher consumption of refined grains were associated with higher risk of having hypercholestrolemia [1.00, 1.07, 1.19, 1.23), hypertriglyceridemia [1.00, 1.17, 1.49, 2.01), hypertension and metabolic syndrome.
Conclusion: Whole grain intake is inversely and refined grain intake is positively associated with the risk of developing metabolic syndrome. Recommendations to increase whole-grain intake may reduce the risk of developing metabolic syndrome.

Abstract

Background: Coronary heart disease is the leading cause of death in many nations. .Hyperlipidemia with elevated serum total cholesterol, LDL cholesterol and triglyceride are known as cardiovascular risk factors. HDL cholesterol is considered to be a protective factor. Any effort for management of dyslipidemia directly reduces cardiovascular mortality and morbidity and cause increasing public health .The ignorance of the extent and impact of hyperlipidemia prompted us to determine the prevalence of hyperlipidemia in Rafsanjan urban population over than 20 years old.
Methods: In this study 247 men and 244 women were evaluated for serum total cholesterol , LDL cholesterol , HDLcholesterol and triglyceride levels.Blood samples were obtained at morning, after 14 hours fasting and for data analysis SPSS-11 soft ware was used. Results: Mean age of subjects was 38.35±13.14 years.High cholesterol level was present in 20.6%, LDL levels were high in 10.8% , 5.7% had elevated level of triglyceride and 8.4% of participants had low HDL cholesterol. Total cholesterol , LDL cholesterol and triglyceride levels were significantly increased by age and HDL levels were also decreased by age.
Conclusion:According to our finding about 29% of studied population had at least one lipid abnormality and this important finding showed very high prevalence of dyslipidemia and requires specific attention and planning.

Abstract

Background: Diabetes Mellitus is a common chronic disease with severe of complications. Proper glycaemic control can prevent these complications considerably. Evaluation of effectiveness of community based and patient centered interventions on glycaemic control, quality of life, patient satisfaction, patient knowledge and reported symptoms were the main aims of this research.
Methods: In a clinical trial, patients referring to Iranian Diabetes Association, who were more than 18 years old, divided to intervention and control group randomly. After three months of general interventions in both groups, including diabetes education and specific interventions including telephone calls, continuous corresponding and sending educational issues in intervention group, changes in variables were studied. Results: Among 52 patients in each group, 17 were male and 42 had type 2 diabetes. The average age was 49 in intervention and 51 in control group. Two groups had no significant difference in age, sex, type of diabetes, treatment method and duration of diabetes, other diseases and education. Both groups showed significant improvement in glycaemic control. The mean reduction in HbA1c was 1.45 in intervention and 0.86 percent in control group the difference is statistically significant (P= 0.02). Patient satisfaction increased in both groups. The satisfaction is significantly higher in intervention group (P=0.000). Knowledge has increased significantly in both groups the difference in groups is not significant. The improvement in Quality of Life was just significant in intervention group. The reported sign and symptoms have not changed in both groups.
Conclusion: Community based and patient centered interventions with emphasis on continuous education and support can improve glycemic control, quality of life, patient satisfaction and patient knowledge in diabetes mellitus.

Abstract

Background: up to know many herbal medicines with different oral formulations have been recommended for diabetes. The aim of this study was to investigate the effect of 4 herbal hypoglycemic agents include garlic (Allium sativum) neem (Azadirachta indica), tulsi (Ocimum sanctum) and bitter gourd (Momordica charantia) on blood glucose, antioxidant enzymes and metal ions in diabetics
Methods: Crude extracts of herbal agents was prepared and each one was given to one group of diabetic rats. Two group of diabetic rats received insulin and glibenclamide. As controls, two groups of healthy and diabetic rats received saline. Body weight, fasting blood glucose, antioxidant enzymes and metal ions were measured before and after the study.
Results: All agents including herbal preparations, insulin and glibenclamide reduced the levels of blood sugar and lipid peroxide when compared with diabetic control. These agents also increased levels of antioxidant enzymes in diabetic rats. Antioxidant enzymes decreased significantly in diabetic controls. Metal ions increased in diabetic rats treated with herbal agents, insulin and glibenclamide but decreased in diabetic controls.
Conclusion: Above mentioned herbal plants may be useful in the treatment of diabetes as they not only have hypoglycemic effect but they also protect rats from free radical mediated cellular injury by improving the activity of antioxidant enzymes. They also improve the levels of metal ions which are associated with antioxidant enzymes.

Abstract

Concept of dietary patterns is new in the filed of nutritional epidemiology. However, it has not been focused to the extent that foods or nutrients have been considered. Although, identifying the association between nutrients and foods intake with chronic diseases is valuable yet, recent evidences have shown that the clinical trials that have used nutrients are not too successful to indicate the effects of that nutrient on the disease risk. On the other hand, the studies used dietary patterns have shown the significant effects on disease risk. Therefore, using dietary patterns analysis is an efficient method to identify diet-disease relations. However, it should be kept in the mind that dietary patterns are different across gender, ethnics, cultures and regions. It is, therefore, recommended that investigators in different countries need to assess their own community dietary patterns and emphasize on these patterns when trying to reduce chronic disease risk. The current study has been conducted to review the studies that have assessed the association of dietary patterns and chronic disease risk.

Abstract

Background: Type 1 diabetes or insulin dependent diabetes mellitus is an autoimmune disease probably caused by various factors such genetics, environmental stresses, viral infections and diet. The disease is associated with damage to pancreatic insulin-producing β cells. Many researches have been performed to study the therapeutic effects of herbal medications on diabetes mellitus. The protective effects of some plants such as Cuminum cyminum, Trigonella foenum-graecum, Saliva sclarea, Allium ampeloprasum etc in diabetes induced rats were reported. Dill with the scientific name of Anethum graveolens, is a plant from umbellifera. This family which contains flavonoid compounds.
Methods: In this research, effects of hydroalchoholic extract of this plant on blood glucose level, lipids and lipoproteins in Alloxan-induced diabetic rats was investigated. Fifteen adult male rats, weighing 200-250 gr, were used in three five member groups. Rats in the control group, received physiological serum. as intraperitoneal (IP). In diabetic control group (DCG), diabetes was induced using Alloxan monohydrate at a dose of 120 mg/kgbw. In addition to diabetes induction just like DCG, the treated diabetic control group (TDCG) rats were dosed with 300 mg/kgbw hydroalcoholic Anethum graveolens extract. All rats received all materials via intraperitoneal injection (IP). 48 hours after the last IP, blood sample was taken from each animal via cardiac puncture to measure blood factors.
Results: The results indicated significant reduction in glucose, total cholesterol, triglyceride, LDL and VLDL levels in TDCG rats compared to DCG rats. Due to the use of dill extract, HDL level was significantly increased.
Conclusion: Effect of Anethum graveolens is related to antioxidant compounds. This compounds affect glucose absorbtion and beta cells regeneration. The results of this research indicate that using hydroalcoholic extract of Anethum graveolens could effectively decrease blood sugar levels.

Abstract

Background: To determine the importance of type 2 Diabetes mellitus as a risk factor for osteoporosis in postmenopausal women, this study was designed in endocrine clinic of zanjan in 2003.
Methods: As a case-control study, 40 diabetic and 40 healthy menopause women have been recruited. These two groups were matched in terms of their age, length of their menopausal period and body mass index. Serum Calcium, Phosphorus, Alkaline phosphatase and Estradiol were measured in all the cases and bone densities in three sites (Femoral neck, lumbar spine and forearm) were evaluated with DXA. All data were analyzed using T-test, analysis of variance, chi-square and multiple regression tests.
Results: The frequency of osteoporosis and osteopenia in diabetic women were not significantly different from non diabetics. The mean bone density in femoral neck was higher in diabetic group (P= 0.013). In both groups there was a significant relationship between bone density and length of menopause (P<0.01) .The relationship between BMI and Bone density was significant only in femoral neck (P<0.01) in both groups. In diabetic women, the higher HbA1c accompanied with the lower bone density in lumbar spine.
Conclusion: Although the level of HbA1c as a marker of blood glucose control, has a relationship with lumbar spine density in diabetics, Diabetes type 2 is not a risk factor for osteoporosis, So screening, diagnosis and management of osteoporosis in diabetes type 2, Should be done independently and according to other risk factors.

Abstract

Background: Many researches have been conducted on islet cells' transplantation for a definitive treatment of diabetes mellitus type1. As the viability of the islets is the most important factor in predicting the transplantation prognosis, we have designed a study to isolate rat's islets. The aim of the study was to assess the viability of the islets at different stages and suggest the best transplantation time.
Methods:
Pancreatic islets were isolated from male rats (250-300gr) by standard surgical procurement followed by intraductal HBSS distension, chopping and digestion with collagenase (type V). After being centrifuged for 3 times, the islets were then hand-picked and incubated in 37oC with RPMI 1640 media for 6 days. Each well contained 35-45 islets. Viability of islets was assessed by 2 independent investigators, giving score 0-2 to the color of islets under florescent microscope after Propidium iodide/Acridine orange staining at 6 times: just after the incubation, 24h, 48h, 3rd day, 5th and 6th day.
Results: The viability of the islet cells was gradually increased after the incubation as we had the most viability rate after the second day, while it decreased after this period and reached the least rate on the 5th and 6th day.
Conclusion:
The islets' viability increased following the cell culture after the isolation procedure, as they have the best condition for transplantation after 48 hours. As the islets’ viability is the most critical point in transplantation, further studies evaluating the effects of different interventions on viability is needed.

Abstract

Background: Artichoke with the scientific name of Cynara scolymuse is a plant from compositae family. In this research, the effect of hydro alcoholic artichoke extract on serum glucose, lipids and lipoproteins and prevention of type 1 diabetes mellitus was investigated.
Methods: Twenty mature male Rats with mean weight of 200-250 gr in four groups were arranged. Rats in the control group, received physiological serum. The Second group (diabetic) received 120 mg/kgbw Alloxan monohydrate. The Third group (diabetic + Glibenclamide) received 0.5 mg/kgbw Glibenclamide in addition of the similar treatment with second group. The Fourth group (Alloxan monohydrate + Cynara scolymus), received 120 mg/kgbw Alloxan monohydrate with 300 mg/kgbw of Cynara scolymus simultaneously. Prescribing materials in all groups was done as interaperitoneal injection(IP). Fourty eight hours after last IP, blood sample was taken from each animal via cardiac puncture to measure blood factors.
Results: The results indicated significant reduction in glucose, cholesterol, triglyceride, VLDL and LDL levels in the treated group with extract and Alloxan monohydrate simultaneously as to compared diabetic group. Also, the result indicated significant increase in HDL level. Hydroalcoholic Artichoke extract could not reduce blood glucose level as compared with Glibenclamide, but had similar effects on other factors in comparison with Glibenclomide.
Conclusion:
Artichoke contains antioxidants compounds, that plays a protective role on beta cells against Alloxan. The results of this research indicate that hydro alcoholic extract of Cynara scolymus could effectively prevent type 1 diabetes mellitus.

Abstract

Background: Limited data are available relating intake of fruits and vegetables to inflammatory markers and risk of metabolic syndrome. The aim of this study was to evaluate the relationship between fruits and vegetables intake and C-reactive protein (CRP) and the prevalence of the metabolic syndrome.

Methods: Fruits and vegetables intake were assessed using a validated semi-quantitative food frequency questionnaire in a cross-sectional study of 486 Tehranian female teachers aged 40-60 y. Anthropometric measurements were done and blood pressure was assessed according to standard methods. Fasting blood samples were taken for biochemical measurements. The metabolic syndrome was defined according to Adult Treatment Panel III guidelines.

Results: The reported mean daily intake of fruits and vegetables were 228±79 and 186±88 g/d respectively. Both fruits and vegetables intake were inversely associated with plasma CRP concentrations. After statistically controlling for age, BMI and waist circumference, mean plasma concentrations of CRP across increasing quintile categories of fruits were 1.94, 1.79, 1.65, 1.61 and 1.56 mg/L respectively (P for trend <0.01) and of vegetables were 2.03, 1.82, 1.58, 1.52 and 1.47 mg/L respectively (P for trend<0.01). These inverse associations remained significant after additional control for other potential confounding variables and dietary factors. After controlling for potential confounders individuals in the highest quintile of fruits intake had 34% (95% CI: 20%-46%) lower and those in the highest quintile of vegetables intake had 30% (95% CI: 16%-39%) lower chance of having the metabolic syndrome compared to those in the lowest quintiles.

Conclusion: In this study higher intake of fruits and vegetables were associated with lower risk of metabolic syndrome part of this association may be mediated through CRP. These findings support current dietary recommendations to increase the intake of fruits and vegetables as a primary preventive measure against cardiovascular disease.

Abstract

Background: Recently on the metabolic syndrome is considered as an inflammatory disease. So factors affecting inflammation are important in this condition.

Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Inflammatory markers were measured by ELISA.

 Results: The difference from the control diet for E-selectin (an inflammatory markers which shows the endothelial function) was -11.4% (P<0.01) on the soy nut consumption and -4.7% (p=0.19) on the soy protein diets. Soy nut consumption reduced interleukin-18 compared to the control diet (difference from the control diet: -9.2%, p<0.01). For C-reactive protein the difference from the control diet was -8.9% (P<0.01) on the soy nut diet and -1.6% (P<0.01) on the soy protein diet.

Conclusion: Short-term soy nut consumption reduced some markers of inflammation and increased plasma nitric oxide levels in postmenopausal women with the metabolic syndrome.

Abstract

The interaction of reducing carbohydrates with proteins leads to a cascade of reactions that are known as glycation or Maillard reaction that have important roles in diabetic complications. In this minireview, structural changes of glycated human serum albumin (GHSA) via various sugars in different incubation times, which reported in scientific literature as well as our research, were reported. Our studies showed glycation induced structural changes for Human Serum Albumin (HSA). In glycation process of HSA after 21 days incubation, glucose separates from HSA and induced the formation of molten globule state that is relative to several diseases that originate from molten globule state in proteins. Also, glycation of HSA induced aggregation states and amyloid formation as well as decreased surface tension which plays a role of denaturant for protein as a surfactant. In following, we showed that alginate as a sugar polymer decreased glycation reaction in HSA. Finally, it is compared the structural changes of artificial and in vitro interaction of sugars with HSA as well as diabetic patients HSA. The results show the number of arginine residues in HSA of diabetic patients is more modified relative to lab samples.

Abstract

Background: Little evidence exists regarding the effects of soy consumption on the metabolic syndrome in humans. We aimed to determine the effects of soy consumption on components of the metabolic syndrome, plasma lipids, lipoproteins, insulin resistance and glycemic control in postmenopausal women with the metabolic syndrome.

Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with the metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Red meat in the DASH diet was replaced by soy protein in the soy protein period and by soy nut in the soy nut period.

Results: Total cholesterol was significantly reduced compared to the control (P<0.01) and soy protein groups (P<0.01). The results were the same regarding the fasting insulin serum (P<0.01 compared with the control and soy protein group), HOMA-IR (P<0.01 compared with the control and soy protein group), Fasting blood sugar (P<0.01 compared with the control and soy protein group), and LDL cholesterol (P<0.01 compared with the control and P<0.05 compared with the soy protein group). Both soy nut and soy protein reduced Apo B100 compared to the control group (P<0.01).  

Conclusion: Short-term soy nut consumption improved glycemic control and lipid profiles in postmenopausal women with the metabolic syndrome
