Understanding the Health Effect of a Bioactive Peptide From Egg: A Pilot Study
A Preliminary Human Study on Bioavailability and Efficacy of Bioactive Peptide IRW in Egg White Hydrolysate
University of Alberta
28 participants
Feb 25, 2026
INTERVENTIONAL
Conditions
Summary
Bioactive peptides derived from food proteins show potential for improving human health. One of such promising peptides is namely IRW made from egg white hydrolysate and composed of three peptides. This is a feasibility study to assess the acute effect of IRW in egg white hydrolysate for the management of high sugar and blood pressure. Participants at high risk of type 2 diabetes (T2D) or having T2D will undergo 4 consecutive treatments of 1 day each (randomly), during which they will consume a standardized breakfast with a smoothie containing different protein powders. Each treatment will be separated by a minimum of 1-week. Participants in the healthy control group will undergo 1 treatment only (one day).

Exclusion Criteria7
- Individuals with a previous history of CVD, renal disorder, monogenic dyslipidemia, with endocrine disorders other than T2D
- Individuals taking chronic anti-inflammatory drugs (including aspirin, antihistamines, and omega-3 supplements)
- Pregnant/lactating women
- Individuals aged above 70 years
- Smokers (current smokers: daily/occasional and those who have smoked more than 100 cigarettes in their life)
- Individuals with specific nutritional restrictions (e.g. vegetarianism excluding eggs from their diet, vegan or with egg allergy) will be excluded
- Individuals with poorly controlled (HbA1c \>12.0%) diabetes or taking exogenous insulin will be excluded. Other anti-diabetic and lipid-lowering medications will be documented.
Interventions
Participants will consume a standardized breakfast (2 slices of 70 g whole wheat bread, 10 g of butter and 30 g of strawberry jam) followed by a smoothie containing the powder. The Egg White Powder will be incorporated in the standardized smoothie containing water, fruits and chocolate/strawberry syrup totaling 250 Kcal. The total calories of the breakfast will be adapted to the calorie needs of each participant to account for 20-25% of their daily calorie intake. After a 9 h fast, blood will be taken before consumption of the standardized breakfast and smoothie (T= 0) and at 5, 10, 20, 30, 60, 90, 120, and 180 min after consumption of the smoothie. Participants will be given 15-25 minutes to eat their breakfast. Urine samples will be collected from participants before the smoothie consumption (0 h) and at 30 min, 90 min, 150 min, 6 hours, 12 hours, and 24 hours following consumption.
