About this study
Official title: A Randomized, Controlled, Cross-over Trial Examining the Effect of Peas in Soup on Post-prandial Glycaemic Response in Healthy Adults.
This study is part of a group of studies whose overall goal is to accurately define the physiochemical and structural effects of pea varieties and relate these to blood glucose attenuation in healthy human volunteers.
Read the detailed description
A randomized, controlled, cross-over study designed to examine the post-prandial glycaemic response to peas in soup will be conducted at the I.H. Asper Clinical Research Institute in Winnipeg, Manitoba. Eligible participants who have provided consent will be asked to attend 3 clinic visits in a fasted state. Participants will be given soup containing peas at 2 visits and soup without peas at 1 visit. At each visit participants will provide 7 capillary blood samples via finger poke, 5 questionnaires about their appetite and a questionnaire about the acceptability of the products. Each visit will last approximately 2.5h and be separated by 3-14 days.

Questions about this trial
What is this clinical trial studying?
A study testing Whole yellow pea soup, Split yellow pea soup and Potato soup in people with Post-prandial Glycaemia, run by St. Boniface Hospital at 1 site in Canada.
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 5 inclusion and 23 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: under way, not looking for participants, as of the sponsor's last update on 29 Nov 2024. 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 Canada. 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?
This study is still under way. Results are not available in the source record yet.
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?
Post-prandial glucose (time frame: 120 min). The study lists 2 primary outcomes in all. 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 NCT03306862, which also lists 11 linked publications.
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 29 Nov 2024.
