Abstract
Dietary fructose induces unfavorable lipid alterations in animal models and adult studies. Little is known regarding metabolic tolerance of dietary fructose in children.
The aim of the study was to evaluate whether dietary fructose alters plasma lipids in children with nonalcoholic fatty liver disease (NAFLD) and in healthy children.
We performed a 2-d, crossover feeding study at the Inpatient Clinical Interaction Site of the Atlanta Clinical and Translational Science Institute at Emory University Hospital.
Nine children with NAFLD and 10 matched controls without NAFLD completed the study. We assessed plasma lipid levels over two nonconsecutive, randomly assigned, 24-h periods under isocaloric, isonitrogenous conditions with three macronutrient-balanced, consecutive meals and either: 1) a fructose-sweetened beverage (FB); or 2) a glucose beverage (GB) being consumed with each meal.
Differences in plasma glucose, insulin, triglyceride, apolipoprotein B, high-density lipoprotein cholesterol, and nonesterified free fatty acid levels were assessed using mixed models and 24-h incremental areas under the time-concentration curve.
After FB, triglyceride incremental area under the curve was higher vs. after GB both in children with NAFLD (P = 0.011) and those without NAFLD (P = 0.027); however, incremental response to FB was greater in children with NAFLD than those without NAFLD (P = 0.019). For all subjects, high-density lipoprotein cholesterol declined in the postprandial and overnight hours with FB, but not with GB (P = 0.0006). Nonesterified fatty acids were not impacted by sugar but were significantly higher in NAFLD.
The dyslipidemic effect of dietary fructose occurred in both healthy children and those with NAFLD; however, children with NAFLD demonstrated increased sensitivity to the impact of dietary fructose.
