| Popis: | Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. NAFLD involves a spectrum of conditions that include pure steatosis without inflammation, nonalcoholic steatohepatitis (NASH), fibrosis and cirrhosis. Insulin resistance (IR) plays a main role in the pathophysiology of NAFLD by causing lipid accumulation in the hepatocytes, which may be followed by lipid peroxidation, production of reactive oxygen species and consequent inflammation. The consumption of carbohydrates, particularly sugars additives high in fructose increased dramatically in the past decades and appears to be at least one very important contributing factor in NAFDL pathogenesis. Recent studies suggest that the excessive consumption of fructose from sugar additives (mainly those found in sweetened beverages and processed foods) is linked to development and severity of NAFLD by induction of IR, postprandial hypertriglyceridemia and lipid accumulation in the liver, especially in individuals with overweight. We discuss the possible mechanisms involving fructose consumption, lipid accumulation and development of NASH. This review also presents the chief findings from all the studies that evaluated fructose consumption in human NAFLD. |
