Brief Summary

A comparison of the glycaemic response and insulinaemic response to glucose, Nutralys S85 Plus pea protein and whey protein using a single-blind, randomised, repeat measure, crossover design trial.

Detailed Description

A single-blind, randomised, repeat measure, crossover design trial will be used to study the glycaemic response and insulinaemic response following consumption of five products: one reference product (50 g available carbohydrate Glucose) and four test products (50 g available carbohydrate Glucose with 10 g NUTRALYS®S85 Plus pea protein, 50 g available carbohydrate Glucose with 20 g NUTRALYS®S85 Plus pea protein, 50 g available carbohydrate Glucose with 10 g Whey protein concentrate and 50 g available carbohydrate Glucose with 20 g Whey protein concentrate).
