Cinnamon supplementation can be a safe and potential adjunct treatment to improve inflammation and clinical symptoms in patients with RA.

BackgroundThe health benefits of pomegranate juice have been reported in several studies. However, limited clinical trials have examined the effects of concentrated pomegranate juice (CPJ) on inflammatory factors.ObjectivesThis study aimed to investigate the effects of CPJ on metabolic risk factors, including inflammatory biomarkers, in patients with type 2 diabetes mellitus.Patients and MethodsIn a quasi-experiment trial, 40 type 2 diabetic patients were asked to consume 50 g of CPJ daily for 4 weeks. Anthropometric indices, dietary intake, blood pressure measurements, and fasting blood samples were conducted at baseline and 4 weeks after the intervention.ResultsThe intake of CPJ produced a significant increase in both total and high-density lipoprotein cholesterol (HDL-C) (4.7% and 3.9%, respectively) from baseline (P < 0.05). However, changes that were observed in serum triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose, and blood pressure were not statistically significant. Administration of CPJ caused significant reduction in serum interleukin-6 (IL-6) (P < 0.05), but tumor necrosis factor-α (TNF-α) and high-sensitivity C-reactive protein (hs-CRP) remained unchanged during the study. The mean value of serum total antioxidant capacity (TAC) was substantially increased (~ 75%) from 381.88 ± 114.4 at baseline to 1501 ± 817 after 4 weeks of CPJ consumption.ConclusionsConsumption of CPJ (50 g/day) appears to have favorable effects on some markers of subclinical inflammation, and to increase plasma concentrations of antioxidants in patients with type 2 diabetes.

We performed a meta‐analysis to evaluate the efficacy of turmeric/curcumin supplementation on serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in patients with nonalcoholic fatty liver disease (NAFLD). We searched PubMed, Scopus, Cochrane Library, ISI Web of Science, and Google Scholar up to November 20, 2018. Studies that examined the effect of turmeric/curcumin on serum concentrations of ALT and AST among patients with NAFLD were included. The mean difference and standard deviation (SD) of changes in ALT and AST between intervention and control groups were used as effect size for the meta‐analysis. A total of six randomized controlled trials (RCTs) were eligible for meta‐analysis. Results from pooled analysis revealed that turmeric/curcumin supplementation reduced ALT (MD: −7.31 UL/L, 95% CI [−13.16, −1.47], p = 0.014) and AST (MD: −4.68 UL/L, 95% CI [−8.75 −0.60], p = 0.026). When RCTs stratified on the basis of their treatment duration, the significant reduction in serum concentrations of ALT and AST was observed only in studies lasting less than 12 weeks. This review suggests that turmeric/curcumin might have a favorable effect on serum concentrations of ALT and AST in patients with NAFLD. However, further clinical trials are needed to confirm these findings.
