About this study

Official title: A Randomized Controlled, Crossover in Design, Double Blind Clinical Trial Investigating the Effects of Whole Versus Processed Fruit Consumption on Risk Factors for Chronic Disease and Performance Indicators.

Acute, randomized, placebo controlled, double blind, postprandial crossover study in male subjects. 4 intervention arms consisting of control, orange juice, whole orange, and processed whole orange to determine the effect of the interventions on the primary measure of flow mediated dilatation (FMD) and additional biomarkers of health. The study will also identify and quantify the main micronutrients and phytochemicals in each of the products and will identify and quantify the main micronutrients and phytochemicals and their metabolites in the subjects' plasma and/or urine. A subset of the study population (n=24) will be invited to participate in an additional arm of the main study which is summarised below.

Being tested
macro- and micro-nutrient matched control (240 ml), Orange juice, whole orange fruit, Processed whole orange

    Measured: change from baseline to 2 hours

  3. global cognitive function

    Measured: change from baseline to 6 hours

  4. Blood pressure

    Measured: change from baseline to 6 hours

  5. postprandial non-esterified fatty acids

    Measured: change from baseline to 6 hours

  6. Postprandial triacylglycerol

  8. Inflammatory status (IL1-beta; IL2; IL6; IL10; IFN-gamma; TNF-alpha; CRP)

    Measured: change from baseline to 6 hours

  9. LDL oxidation

    Measured: change from baseline to 6h

Questions about this trial

What is this clinical trial studying?

A study testing Orange juice, whole orange fruit and Processed whole orange in people with Vascular Stiffness, run by University of Reading at 1 site in United Kingdom.

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 13 inclusion and 13 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 Oct 2013. 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 Kingdom. 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. Some participants in this study may receive a placebo. 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?

Flow mediated dilation (time frame: change in Flow Mediated Dilation response between baseline and 6 hours). 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 NCT01963416, 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 Oct 2013.
