Dietary factors contribute to fat accumulation in the liver, and early intervention is key to helping patients. It ranges in severity from simple steatosis excessive fat accumulation to steatohepatitis liver cell injury and inflammation. NASH can progress to cirrhosis and hepatocellular carcinoma. Most patients with a fatty liver have excess body weight; obesity is a common and well-documented risk factor for NAFLD and a predictor of advanced disease. Sustained weight loss is the most effective treatment and should be the foundation of any treatment plan. Sufficient weight reduction can be an effective treatment to improve the histology of NASH. RDs are the cornerstone of NAFLD treatment and should be up-to-date on the current recommendations for medical nutrition therapy. A nonpharmacological intervention based on personalized diet, physical activity, and behavior therapy should aim to encourage lifestyle change, the only therapy proven to effectively treat NAFLD. This continuing education course reviews the dietary factors associated with NAFLD as well as the lifestyle and nutrition options for treating the disease.
The risk factors mainly associated with NAFLD are diseases related to the metabolic syndrome, genetics and environment. In this review, we provide a literature compilation evaluating the evidence behind dietary components, including calories intake, fat, protein, fibers and carbohydrate, especially fructose which could be a trigger to development and progression of the NAFLD. In fact, it has been demonstrated that diet is an important factor for the development of NAFLD and its association is complex and extends beyond total energy intake. Non-alcoholic fatty liver disease NAFLD is one of the most common forms of liver disease primarily related to the progressive increase of obesity in the world. Initially, it was considered to be a liver disease with benign course, however, it is currently known to be a complex disease which involves environmental factors and genetic predisposition 1. NAFLD ranges from simple Steatosis to non-alcoholic steatohepatitis NASH that can have different degrees of fibrosis and progress to liver cirrhosis and hepatocellular carcinoma HCC in patients with no history of alcoholism 2. Sedentary lifestyle, inadequate intake of foods with high fat and fructose consumption, as well as obesity, metabolic syndrome MtS, type 2 diabetes mellitus T2DM, hormonal status and genetic background have been described as responsible for the development of NAFLD 3. Due to increasing rates of obesity, NAFLD has become more prevalent in all populations, especially in the Western world and has been defined by specialists as the disease of the modern world 4. However, this prevalence differs significantly according to the diagnostic method used and the population studied. Balanced and healthy nutrition is one of the main determinants of nutritional status that can prevent many diseases, such as NAFLD. In fact, an inadequate diet, with a high concentration of saturated fat and cholesterol, simple carbohydrates and xenobiotics, or external contaminants, which lacks in vitamins and fibers, is an important factor for the development of NAFLD.
