In addition , there was a low level of evidence that hypercaloric fructose and glucose diets have similar effects on liver fat and liver enzymes in healthy adults .
There was insufficient evidence to draw a conclusion for effects of HFCS or sucrose on NAFLD .
Conclusions : On the basis of indirect comparisons across study findings , the apparent association between indexes of liver health ( ie , liver fat , hepatic de novo lipogenesis , alanine aminotransferase , AST , and γ-glutamyl transpeptase ) and fructose or sucrose intake appear to be confounded by excessive energy intake .
Overall , the available evidence is not sufficiently robust to draw conclusions regarding effects of fructose , HFCS , or sucrose consumption on NAFLD
Background : Concerns have been raised about the concurrent temporal trend between simple sugar intakes , especially of fructose or high-fructose corn syrup ( HFCS ) , and rates of nonalcoholic fatty liver disease ( NAFLD ) in the United States .
Objective : We examined the effect of different amounts and forms of dietary fructose on the incidence or prevalence of NAFLD and indexes of liver health in humans .
Prevalence of nonalcoholic fatty liver disease and nonalcoholic steatohepatitis among a largely middle-aged population utilizing ultrasound and liver biopsy: a prospective study.
BACKGROUND & AIMS Prevalence of nonalcoholic fatty liver disease ( NAFLD ) has not been well established . The purpose of this study was to prospect ively define the prevalence of both NAFLD and nonalcoholic steatohepatitis ( NASH ) . METHODS Out patients 18 to 70 years old were recruited from Brooke Army Medical Center . All patients completed a baseline question naire and ultrasound . If fatty liver was identified , then laboratory data and a liver biopsy were obtained . RESULTS Four hundred patients were enrolled . Three hundred and twenty-eight patients completed the question naire and ultrasound .  Mean age ( range , 28 - 70 years ) was 54.6 years ( 7.35 ) ; 62.5 % Caucasian , 22 % Hispanic , and 11.3 % African American ; 50.9 % female ; mean body mass index ( BMI ) ( calculated as kg/m(2 ) ) was 29.8 ( 5.64 ) ; and diabetes and hypertension prevalence 16.5 % and 49.7 % , respectively . Prevalence of NAFLD was 46 % . NASH was confirmed in 40 patients ( 12.2 % of total cohort , 29.9 % of ultrasound positive patients ) . Hispanics had the highest prevalence of NAFLD ( 58.3 % ) , then Caucasians ( 44.4 % ) and African Americans ( 35.1 % ) . NAFLD patients were more likely to be male ( 58.9 % ) , older ( P = .004 ) , hypertensive ( P < .00005 ) , and diabetic ( P < .00005 ) . They had a higher BMI ( P < .0005 ) , ate fast food more often ( P = .049 ) , and exercised less ( P = 0.02 ) than their non-NAFLD counterparts . Hispanics had a higher prevalence of NASH compared with Caucasians ( 19.4 % vs 9.8 % ; P = .03 ) . Alanine aminotransferase , aspartate aminotransferase , BMI , insulin , Quantitative Insulin-Sensitivity Check Index , and cytokeratin-18 correlated with NASH . Among the 54 diabetic patients , NAFLD was found in 74 % and NASH in 22.2 % . CONCLUSION Prevalence of NAFLD and NASH is higher than estimated previously . Hispanics and patients with diabetes are at greatest risk for both NAFLD and NASH
