Not Applicable

Active, not recruiting

• Conditions: Post-prandial Glycaemic Response; Satiety

• Registration Number: NCT03306927
• Lead Sponsor: St. Boniface Hospital

Brief Summary

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 and appetite related sensations in healthy human volunteers.

Detailed Description

A randomized, controlled, cross-over study designed to examine the PPGR and appetite related sensations to peas in chili 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 4 clinic visits in a fasted state. Participants will be given vegetarian chili containing peas at 2 visits and rice at 2 visits. At each visit participants will provide 7 venous blood samples via indwelling catheter, 7 capillary blood samples via finger poke, 2 urine samples, 5 questionnaires about their appetite and a questionnaire about the acceptability of the products. At the end of each visit, participants will eat pizza ad libitum, and the amount of pizza consumed will be measured to determine if the peas influenced the amount of calories consumed at lunch. Participants will record their food/beverage intake for the rest of the day. Each visit will last approximately 3h and be separated by 3-14 days.
