The effect of moderate alcohol consumption on nonalcoholic fatty liver disease

[ABSTRACT] Non-alcoholic fatty liver disease (NAFLD) is accepted as a counterpart to alcohol-related liver disease (ARLD) since it is defined as a hepatic steatosis without excessive use of alcohol. However, the amount of moderate alcohol consumption is controversial, and previous studies have shown heterogeneous evidence of whether moderate alcohol consumption is beneficial or detrimental. In this review, we compare and summarize the findings of studies with high-quality evidence for the impact of moderate alcohol consumption in NAFLD patients to date.
