With the worldwide spread of diet westernization, sedentary lifestyle, and obesity, non-alcoholic fatty liver disease (NAFLD) has becoming frequent disorder. NAFLD is the presence of hepatic fat infiltration more than 5% of liver cells, in lack of alcohol abuse or steatogenic drugs. NAFLD includes a spectrum of liver disorder, ranging from steatosis and non-alcoholic steatohepatitis (NASH) to fibrosis, cirrhosis and hepatocellular carcinoma (1). Metabolic syndrome and systemic micro-inflammation are the most relevant metabolic disorders related to this spectrum of diseases (2). There is currently no approved pharmacological treatment for NAFLD. The management strategy of NAFLD involves lifestyle interventions, including diet, exercise, and behavior modification (1).
