About

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.

Full 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.
