Functional and Value-Added Dairy Products and Blood Glucose Control

Not Applicable

Completed

• Conditions: Metabolic Disease; Overweight and Obesity; Blood Glucose, High

• Registration Number: NCT05400694
• Lead Sponsor: Mount Saint Vincent University

Brief Summary

Milk proteins possess multiple biological activities including their effect on blood glucose control, satiety and energy intake. The design of functional food products with added milk protein fractions has many challenges related to their inferior sensory properties. Chocolate milk presents the universal vehicle for added milk protein fractions that might partially mask their sensory characteristics. However, commercially produced chocolate milk has a significant amount of added sugar. This project will investigate the properties of a value-added dairy product (chocolate milk with reduced sugar content) enriched with individual milk protein fractions on characteristics of blood glucose control, satiety and energy intake in young healthy adults.
