Study Details

Study Description

Brief Summary

It is hypothesized that yellow pea protein and fiber will reduce short-term food intake, subjective appetite and glycemic response.

Condition or Disease	Intervention/Treatment	Phase
Obesity Type II Diabetes Mellitus Metabolic Syndrome	Dietary Supplement: yellow pea protein Dietary Supplement: yellow pea fiber Dietary Supplement: Control Tomato Soup	N/A

Detailed Description

A within-subject, randomized study was conducted. Each subject returned 5 times, 1 week apart, and received 1 of the 5 treatments per week. The 5 treatments were tomato soup with 10 or 20 g of isolated yellow pea fibre or protein, or a control soup with no added pea fractions. Food intake was measured at an ad libitum pizza meal served 30 minutes after treatment. Satiety and blood glucose (via finger prick) were measured throughout the treatment period.
