Trial summary

This study aims to find out how consuming different proteins with rice affect metabolism. Most meals the investigators eat predominantly consist of a carbohydrate and protein (i.e. rice, noodles, bread etc with meats or seafood). Read more about this study

About this study

This study aims to find out how consuming different proteins with rice affect metabolism. Most meals the investigators eat predominantly consist of a carbohydrate and protein (i.e. rice, noodles, bread etc with meats or seafood). However, it is still unknown how consuming different proteins with commonly eaten carbohydrates affect metabolism. Previous studies have shown that proteins stimulate hormones such as insulin, glucagon and gut hormones. However, the extent of the response depends on protein type. The metabolic responses to carbohydrates have also been shown to be greatly affected when they are eaten with proteins. However, most of the previous studies have used glucose as the carbohydrate and it is still unknown how eating proteins with carbohydrate foods such as rice affect metabolism. Therefore, this study has been initiated to determine the metabolic effects of eating different protein types with rice. Using the most common carbohydrate eaten in Asia (rice) and four commonly eaten protein foods (egg, chicken, fish and beancurd), this study aims to observe the metabolic effects of co-ingesting proteins and carbohydrate. The resulting data will provide valuable insights into the metabolic effects of protein-carbohydrate meals and will be useful in the development of practical advice and dietary guidelines for those with chronic diseases (such as diabetes and obesity).

Read the detailed description

The study will recruit 20 healthy Chinese male subjects from the general public over a period of one year. The test foods will be rice, rice with egg, rice with fish, rice with chicken and rice with beancurd.Potential participants will have to come on one morning in an overnight fasted state for consenting and screening procedures. Only those fulfilling the inclusion and exclusion criteria will be admitted into the study. Each participant will be required to come on 5 non-consecutive days, with each session lasting approximately 4 hours. On each day, participants will arrive at the laboratory between 8-9 am following an overnight fast. An indwelling catheter will be inserted into a vein in their forearm or antecubital fossa and kept patent. Baseline blood samples will be obtained after which they will be given the test food to consume. Further blood samples will be taken at periodic intervals for the subsequent 3.5 hours. Blood samples will be taken every 15 minutes in the first 60 minutes and every 30 minutes for the remaining 150 minutes. At every time point blood samples will be extracted from a finger prick (for measuring glucose) and from the cannula (for measuring all other metabolites). At the same time points subjects will have to fill in visual analogue scales on feelings of hunger and satiety.

Questions about this trial

What is this clinical trial studying?

A study testing White rice, Rice with chicken breast and Rice with fish in people with Metabolic Diseases, run by Singapore Institute of Food and Biotechnology Innovation.

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 12 inclusion and 0 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 15 May 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

Blood glucose response (incremental area under the curve) measured using the hemocue (time frame: 3.5 hours post consumption). The study lists 3 primary outcomes in all. 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 15 May 2019.
