About this study

Official title: Impact of Orange Juice Consumption on Glucose Homeostasis and Antioxidative Status in Healthy Subjects

Aim of the study is to investigate the impact of orange juice consumption (with meals or between meals) as well as sugar sweetened beverage (SSB) consumption (between meals) on glucose homeostasis and antioxidative status.

Read the detailed description

Duration of the study is 3x three weeks including one wash-out week each followed by two weeks of juice/SSB consumption under free living conditions.

During wash-out weeks consumption of orange juice or citrus fruits is restricted.

During intervention weeks, participants are asked to eat three regular meals per day without snacking. Intervention weeks are (i) orange juice consumption with meals (ii) orange juice consumption between meals and (iii) SSB consumption between meals. Daily energy intake with orange juice/SSB is 20% of individual energy requirement. Additional caloric beverages (SSB, juice, coffee with sugar/milk, alcohol) are not allowed. At the beginning and the end of each intervention phase insulin sensitivity and antioxidative status are assessed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. changes in daylong glycaemia between pre and post intervention periods

    measured via continuous glucose monitoring [mg/dL]

    Measured: two weeks

Secondary outcomes (3)
  1. changes in uric acid between pre and post intervention periods

    measured via uric acid serum levels [mg/dL]

    Measured: two weeks

  2. changes in insulin sensitivity between pre and post intervention periods

    measured via "Matsuda-Index" from oral glucose tolerance test data

    Measured: two weeks

  3. changes in antioxidative status between pre and post intervention periods

    measured via vitamin c blood levels [mg/L]

    Measured: two weeks

Questions about this trial

What is this clinical trial studying?

A study testing Orange juice with meals, Orange juice between meals and Sugar sweetened beverage between meals in people with Healthy, run by University of Hohenheim at 1 site in Germany.

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 1 inclusion and 6 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 25 Apr 2017. 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 Germany. 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?

changes in daylong glycaemia between pre and post intervention periods (time frame: two weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Apr 2017.
