About this study

Official title: Pharmacokinetics and Pharmacodynamics of Fructose Following Soft Drink Consumption: Sucrose vs High Fructose Corn Syrup

The purpose of this study is to determine whether sucrose vs high fructose corn syrup from a soft drink results in differences in various metabolic byproducts such as fructose, glucose, serum uric acid, triglyceride and lactate.

Read the detailed description

Fructose consumption has risen sharply during the past several decades. Since its introduction to the United States in 1967, high fructose corn syrup (HFCS) has overtaken sucrose as the main sweetener in manufactured foods and beverages, and thus, is responsible for the approximately 30% increase in fructose in our diet. Numerous studies have shown that excessive fructose consumption can cause a variety of harmful metabolic effects, suggesting that fructose may partially be responsible for the current epidemic in obesity, hypertension, metabolic syndrome, and diabetes.

This preliminary study will investigate the pharmacokinetics and pharmacodynamics of fructose in a broad population. Specifically, the goal of our research are to compare the impact of the two main sources of dietary fructose, sucrose versus HFCS, on fructose bioavailability and acute metabolic changes by measuring response phenotypes, such as serum uric acid, lactate, and triglyceride levels.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by University of Florida at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fructose (time frame: baseline, 15min, 30 min, 60 min, 90 min, 2 hr, 3 hr, 4.5 hr, 6 hr). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00661947, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Feb 2012.
