A meta-analysis of epidemiological studies investigating the association between alcohol consumption and NAFLD risk was carried out by a team of Argentinean researchers from the University of Buenos Aires (Argentina). Eight studies with 43,175 adults (30,791 non-drinkers and 12,384 modest drinkers (defined as < 40 grams alcohol per day) were included. The analysis showed that moderate consumption of alcoholic beverages was associated with a significant protective effect, i.e. a 31% lower risk of having NAFLD. Further, moderate alcohol consumption was associated with a 50% lower risk of developing an advanced disease stage (1).
