It is believed to havebeneficial effects in the prevention and treatment of many diseases, one of which is nonalcoholicfatty liver disease (NAFLD). The present study investigated the effects of consumption of greentea in NAFLD patients. Methods: This study was a double?blind, placebo?controlled, randomized clinical trial. Ultrasonography was used to diagnose fatty liver in patients with alanine aminotransferase (ALT)>31 mg/dl and 41 mg/dl and aspartate aminotransferase (AST)>31 mg/dl and 47 g/dlin women and men, respectively and without other hepatic diseases. A total of 80 participants (20–50 years) with NAFLD were randomly allocated into two groups to receive either green teaextract (GTE) supplement (500 mg GTE tablet per day) or placebo for 90 days. At baseline andat the end of the intervention weight, serum ALT, AST, and alkaline phosphatase (ALP) weremeasured in fasting state, and dietary data were collected at baseline and end of the study. Results: Green tea group showed significant reductions in ALT and AST levels after 12 weeksperiod (P Conclusions: According to the findings of this study, GTE supplementation decrease liverenzymes in patients with NAFLD. It can be claimed that GTE prescribed can be considered asa treatment to improve serum levels of liver enzymes in NAFLD patients.
