The Effect of Whey Protein and Its Hydrolysate on Pre- and Post-Fixed Meal Glycemia and Insulin in Young Adults

The Effect of Whey Protein and Its Hydrolysate on Pre- and Post-Fixed Meal Glycemia and Insulin in Young Adults

The purpose of this study is to describe relationships among whey protein and its hydrolysate when consumed before a meal on pre- and post-fixed meal satiety, blood glucose and insulin in healthy young adults.

A randomized, cross-over design study was conducted. Whey protein preloads (5-40 g) and hydrolysate whey protein (10 g) were provided in 300 ml water. At 30 min following consumption, subjects were fed a preset pizza meal (12 kcal/kg, experiment 2). Satiety, insulin and blood glucose were measured at baseline and selected intervals pre- and post-meal.

Inclusion Criteria:

• normal body weight

Exclusion Criteria:

• breakfast skippers

• dieters or individuals with diabetes (fasting blood glucose ≥ 7.0 mmol/L) or other metabolic diseases
