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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
47

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.
Behavioral: High fructose corn syrup diet
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.
Behavioral: Standard diet (low in high fructose corn syrup)
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.
Behavioral: High fructose corn syrup diet
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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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.
