【Abstract】：Nonalcoholic fatty liver disease (NAFLD) is defined as hepatic steatosis without heavy drinking (the amount of alcohol intake is limited within the safe threshold), and the difference between NAFLD and alcoholic liver disease is largely dependent on the amount of alcohol intake. Alcohol intake and NAFLD coexist in a considerable proportion of the population, and this proportion is increasing continuously. There are still controversies over the definition of “safe threshold” and whether moderate drinking within the “safe threshold” has a protective effect against NAFLD, so as to improve the adverse outcome and survival prognosis of chronic liver diseases. This article elaborates on the above ideas, and it is believed that we should pay attention to individualized risk assessment when evaluating the influence of drinking on NAFLD and follow the principle of individualization when judging the benefits and harms of drinking and giving suggestions for drinking.
