Drinking Alcohol and Risk of Non-alcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the developed world and affects about one-third of the total population of the United States.

NAFLD is a major risk factor for cardiovascular disease, which is the major cause of death in developed countries around the world. It is also a major cause of hepatic dysfunction among children.

Researchers examined the effects of moderate drinking on non-alcoholic steatohepatitis (NASH) or liver inflammation caused by a buildup of fat in the organ. The disease can get worse causing scarring of the liver and cirrhosis. NASH is a major characteristic or feature of non-alcoholic fatty liver disease.

An analysis of participants in the United States National Institute of Health's NASH Clinical Research Network who had non-alcoholic fatty liver disease compared lifelong non-drinkers to moderate drinkers. The results demonstrated that the risk of NASH dropped as the consumption of alcohol increased up to the highest levels of moderate consumption.

Moderate drinkers also had a significantly lower risk of suffering from fibrosis and as well as ballooning hepatocellular injury than lifetime alcohol abstainers.

It is important to know that people with NAFLD are much more likely to die of cardiovascular disease than of liver disease and that moderate drinking reduces the risk of death from cardiovascular disease by almost half.
