High Fructose Corn Syrup (Fructose)

March 22, 2017 updated by: Washington University School of Medicine

The Effect of High Fructose Corn Syrup Feeding in Nonalcoholic Fatty Liver Disease

The purpose of this research study is to learn more about how high fructose corn syrup, a sugar used to sweeten drinks and foods, affects metabolism in obese persons with and without nonalcoholic fatty liver disease. Eligible participants will be studied before and after eating a diet high in high fructose corn syrup or a standard diet (low in high fructose corn syrup) for four weeks.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: NAFLD
Subjects with nonalcoholic fatty liver disease (NAFLD) will complete baseline testing and then be assigned to either the high fructose corn syrup diet or the standard diet (low in high fructose corn syrup) for 4 weeks. Post intervention testing will be completed after the subjects have completed the 4 week diet intervention.
Subjects will consume a high fructose corn syrup diet for 4 weeks. The food will be prepared by the bio-nutrition kitchen, and meals will be picked up every 3-4 days.
Subjects will consume a standard diet (low in high fructose corn syrup) for 4 weeks. The food will be prepared by the bio-nutrition kitchen, and meals will be picked up every 3-4 days.
ACTIVE_COMPARATOR: Non-NAFLD
Subjects without nonalcoholic fatty liver disease (Non-NAFLD) will complete baseline testing and then be fed a high fructose corn syrup diet for 4 weeks. Post intervention testing will be completed after the subjects have completed the 4 week diet intervention.
Subjects will consume a high fructose corn syrup diet for 4 weeks. The food will be prepared by the bio-nutrition kitchen, and meals will be picked up every 3-4 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in intrahepatic triglyceride (IHTG) content
Time Frame: 4 weeks
Determine the effect of 4-week isocaloric diet high in high fructose corn syrup (HFCS) on IHTG content measured by magnetic resonance spectroscopy (MRS).
4 weeks
Hepatic lipid metabolism
Time Frame: 4 weeks
Determine the effect of 4-week isocaloric diet high in HFCS on hepatic lipid metabolism [de novo lipogenesis, very low density lipoprotein-triglyceride (VLDL-TG) and very low density lipoprotein-Apolipoprotein B100 (VLDL-ApoB) secretion rates] by using stable isotope tracer methods.
4 weeks
Multi-organ insulin sensitivity
Time Frame: 4 weeks
Determine the effect of 4-week isocaloric diet high in HFCS on multi-organ insulin sensitivity by using a one stage hyperinsulinemic euglycemic clamp procedure in conjunction with muscle and adipose tissue biopsies.
4 weeks
Uric acid metabolism
Time Frame: 4 weeks
Determine the effect of 4-week isocaloric diet high in HFCS on uric acid metabolism by measuring post-prandial serum uric acid concentrations and using stable isotope tracer method.
4 weeks
