Abstract

Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and refers to the accumulation of triglycerides in hepatocytes. Recent studies have showed that resveratrol (antioxidant of grape) can be effective in the treatment of NAFLD through its inhibitory effect on lipid accumulation. Method: We systematically searched databases including: ISI web of science, Scopus, PubMed and Embase by using related keywords. Then, by considering inclusion and exclusion criteria, appropriate articles were selected. All the analyses were conducted in Review Manager (RevMan) Version 5.3. Results: Finally, 6 RCTs were included in meta-analysis and systematic review. Our results showed that resveratrol supplementation significantly reduced levels of TNF-alpha (SMD = −0.46; 95% CI (−0.78, 0.14); P = 0.005) and hs-CRP (SMD = −0.53; 95% CI (−1.01, −0.05); P = 0.030), but for other markers (BW, BMI, WC, HC, WHR, SBP, DBP, ALT, AST, GGT, ALP, bilirubin, TC, TG, HDL, LDL, LDL to HDL ratio, apo-A1, apo-B, insulin, HOMA-IR, glucose, creatinine and IL-6), no significant change was observed. Conclusion: Overall, the results of the present study show that resveratrol supplementation does not affect the management of NAFLD although it can improve some inflammatory markers. © 2020
