About this study

This study hypothesizes that milk protein consumed together or shortly before a white rice or white bread carbohydrate meal exerts different influence on the glycaemic, insulinaemic responses.

Read the detailed description

Consumption of milk proteins increase satiety and reduce glucose response when consumed alone or with carbohydrate. Milk proteins are of interest because proteins are more satiating than either carbohydrate or fat, and they regulate food intake and metabolic functions by the intact protein, encrypted peptides and amino acids on gastrointestinal and central pathways. White rice and white bread are two common carbohydrates types mostly consumed in Asia. Both of them are known to result in high glycaemic and insulinaemic responses. However, in most meals, they are accompanied by other foods such as soy milk, cow milk products. The glyceamic and insulinaemic responses are determined by the type of protein and the type of carbohydrates. And also the consumption time of protein and carbohydrate. Recent research points to an intrinsic value of small amounts of milk protein or dairy consumed shortly before a meal can reduce the glycemic response to carbohydrate and that this is not at the cost of increased demand for insulin. The objective of the present study is to investigate how glycaemic, insulinaemic and satiety responses to a white rice or white bread meal changed when a soy milk or cow milk consumed together or shortly before the meal. Whole soy milk and whole cow milk will be added to the meal. Healthy subjects (n 15) will ingest the test meals once. The meals will be provided as breakfasts, on 10 different occasions, in random order with ≥ 7 days between each. Blood samples (from the cannula and finger pricks) will be then drawn for 3 h, and glucose and serum insulin, plasma glucagon, satiety markers, inflammation markers, amino acids et.al will be analysed. The objective of the study is determining if different liquid protein consumed shortly before or with carbohydrate has different effects on metabolism. And also we will compare the difference of white rice and white bread. Determining the consuming time effect, milk protein type and carbohydrate type on glycaemic and insulinaemic are critical for the provision of dietary advice and formulation of public health guidelines.

What is being measured

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

  1. Glucose response of different treatments

    The blood glucose will be measured by Hemocue 201 from finger prick. Venous blood will be collected at the same time points.

    Measured: 3.5 hrs post consumption

Secondary outcomes (1)
  1. Gastric emptying rate

    Measurement of gastric emptying rate using real-time ultrasonography (GE LOGIQ P5 ultrasound in CNRC). Ultrasound measurements will be taken with subjects in a supine position during fasting, then at 15-30 min intervals after consumption of the test meal.

    Measured: 2 hours post consumption

Questions about this trial

What is this clinical trial studying?

A study testing Bread, Soy milk and cow milk and real-time ultrasonography (GE LOGIQ P5 ultrasound in CNRC) in people with Diabetes and Impaired Glucose Tolerance, run by Singapore Institute of Food and Biotechnology Innovation at 1 site in Singapore.

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 7 inclusion and 3 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 2 Feb 2016. 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 Singapore. 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?

Glucose response of different treatments (time frame: 3.5 hrs post consumption). 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 NCT02151188, 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 2 Feb 2016.
