Ginger improved insulin sensitivity and some fractions of lipid profile, and reduced CRP and PGE₂ in type 2 diabetic patients. Therefore ginger can be considered as an effective treatment for prevention of diabetes complications.
Five hundred milligrams per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and HAQ in women with RA.
BackgroundType 2 diabetes (T2D) is accompanied by elevated inflammation, oxidative stress, hyperlipidemia and hyperglycemia which all contribute to cardiovascular disease pathogenesis. Saffron as a complementary medicine and source of antioxidants could play a role in alleviating diabetes and its complications. The aim of this study was to determine the effects of saffron supplementation as an adjunct therapy in T2D.Patients and methodsThis randomized controlled trial included 80 T2D patients with a mean age of 54.1 years. Participants were randomly assigned into two groups to take either saffron tablets (100 mg/day; n=40) or placebo (n=40) for 12 weeks. Fasting blood samples were obtained at the beginning and after the intervention period to quantify glycemic factors, lipid profile, and biomarkers of inflammation and oxidative stress. Anthropometric indices and dietary intakes were also measured at baseline and at study end.ResultsCompared with placebo, saffron supplementation resulted in significant decreases in waist circumference (p<0.001) and malondialdehyde (MDA) (p=0.001). There was no statistically significant difference in other indices, including anthropometric parameters, serum insulin, fasting blood glucose, HbA1c, insulin sensitivity indices, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, and tumor necrosis factor-α between the study groups (p>0.05).ConclusionOverall, 12 weeks of saffron supplementation in diabetic patients had beneficial effects on waist circumference and serum MDA levels. However, saffron did not influence other evaluated cardio metabolic risk markers in diabetic patients.
Background: Type 2 diabetes is a growing public health problem and is associated with increased morbidity and mortality. The
worldwide prevalence of type 2 diabetes is rising. Polyphenols, such as flavonoids, phenolic acid, and stilbens, are a large and heterogeneous
group of phytochemicals in plant-based foods. In this review, we aimed at assessing the studies on polyphenols and diabetes
management.
Methods: A literature search in the PubMed, EMBASE, Scopus, and ISI Web of Science databases was conducted to identify relevant
studies published from 1986 to Jan 2017.
Results: Several animal models and a limited number of human studies have revealed that polyphenols decrease hyperglycemia and
improve acute insulin secretion and insulin sensitivity. The possible mechanisms include decrease in glucose absorption in the intestine,
inhibition of carbohydrates digestion, stimulation of insulin secretion, modulation of glucose release from the liver, activation of
insulin receptors and glucose uptake in insulin-sensitive tissues, modulation of intracellular signaling pathways, and gene expression.
Conclusion: Growing evidence indicates that various dietary polyphenols may influence blood glucose at different levels and may
also help control and prevent diabetes complication. However, we still need more clinical trials to determine the effects of polyphenols-
rich foods, their effective dose, and mechanisms of their effects in managing diabetes.
BACKGROUND
According to previous studies, probiotic and prebiotic supplementation have desirable effects
on glycemic parameters. Thus far, the effect of supplementation on the glycemic parameters and
adipokines in non-alcoholic fatty liver disease (NAFLD) has not been assessed. Therefore, the
aim of this study was to determine the effects of supplementation with probiotic and prebiotic on
adiokines and glycemic parameters in the patients with NAFLD.
METHODS
In the present randomized, double-blind, placebo-controlled trial, 89 patients with NAFLD
were randomly divided into three groups to receive one probiotic capsule + 16 g/d maltodextrin
(probiotic group) or 16 g/d oligofructose powder + one placebo capsule (prebiotic group), and
one placebo capsule + 16 g/d maltodextrin (control group) for 12 weeks. All the subjects in the
study were advised to follow the weight loss diet and physical activity recommendations during
the intervention. Fasting blood samples were taken at baseline and after the intervention to measure
leptin, adiponectin, insulin, and fasting blood sugar.
RESULTS
At the end of the study, serum concentrations of leptin, insulin, and HOMA-IR decreased
significantly in the probiotic and prebiotic groups compared with the control group. Despite the
changes within the groups, serum concentrations of adiponectin did not change significantly between
the three groups. Also, fasting blood sugar did not change between the groups, but decreased in the
prebiotic group. Quantitative insulin-sensitivity check index (QUICKI) increased significantly in
probiotic and prebiotic groups compared with the control group.
CONCLUSION
Probiotic and prebiotic supplementation along with lifestyle intervention has a favorable impact
on glycemic parameters and leptin levels compared with lifestyle intervention alone.
Rheumatoid arthritis (RA) is a systemic autoimmune and inflammatory disease. Our study aimed to determine the effect of saffron supplement on clinical outcomes and metabolic profiles in patients with active RA. In this randomized, double‐blind, placebo‐controlled trial, 66 women older than 18 years old received 100 mg/day either saffron supplement in the intervention group (n = 33) or matched placebo in the placebo group (n = 33) for a period of 12 weeks. Sixty‐one patients (30 in the control and 31 in the saffron group) remained for the final analysis. No adverse effects were reported by the patients. Saffron supplementation significantly decreased the number of tender (−1.38 ± 1.66 vs. 0.10 ± 0.40, p < .001) and swollen (−2.12 ± 2.34 vs. 0.63 ± 2.79, p < .001) joints, pain intensity based on visual analogue scale (−18.36 ± 15.07 vs. −2.33 ± 5.04), p < .001), and disease activity score (DAS28) (−0.75 ± 0.67 vs. 0.26 ± 0.77, p < .001) at the end of intervention between the two groups and in saffron group compared with baseline values. Physician Global Assessment (p = .002) and erythrocyte sedimentation rate were significantly improved after intervention (24.06 ± 12.66 vs. 32.00 ± 14.75, p = 0.028). High‐sensitivity C‐reactive protein reduced at the end of the intervention in the saffron group compared with baseline values (12.00 ± 7.40 vs. 8.82 ± 7.930, p = .004). Tumor necrosis factor alpha, interferon gamma, and malondialdehyde were decreased, and total antioxidant capacity were increased, but their differences between the two groups were not significant (p > .05). According to the results, saffron supplements could positively and significantly improve clinical outcomes in RA patients.
