Globally, the rise in prevalence of obesity and metabolic syn-drome as a whole has been linked to increased access toprocessed foods, such as refined sugars and saturated fats.Consequently, nonalcoholic fatty liver disease (NAFLD) is onthe rise in both developed and developing nations. However,much is still unknown on the NAFLD phenotype with regardsto the effect of ethnic diversity. Despite similarities in dietaryhabits, it appears that certain ethnicities are more protectedagainst NAFLD than others. However, manifestations of thesame genetic polymorphisms in different groups of people in-crease those individuals' predisposition to NAFLD. Diets fromdifferent regions have been associated with a lower preva-lence of NAFLD and have even been linked to regression ofhepatic steatosis. Socioeconomic variations amongst differ-ent regions of the world also contribute to NAFLD prevalenceand associated complications. Thus, a thorough understand-ing of ethnic variability in NAFLD is essential to tailoring treat-ment recommendations to patients of different backgrounds.
