Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the postprandial metabolic responses to plant-based protein ingredients of different degrees of processing (pea protein concentrate, isolate, and extrudate) and in comparison to whey protein in healthy adults. Therefore, young healthy subjects consume 4 test meals with 25 g of protein from pea protein concentrate, pea protein isolate, pea protein extrudate or whey protein in a randomized order. In a postprandial period of 6 hours, parameters of protein and glucose metabolism (i.a. plasma amino acids), gastric emptying and hunger/satiety are analysed. It is assumed that the plasma amino acid profile after plant protein ingestion differs depending on processing level of the protein ingredients and in comparison to whey protein.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In a randomized crossover-design, 20 healthy women and men consume 4 test meals containing either 25 g of protein from plant protein ingredients (pea protein concentrate, isolate, or extrudate) or whey protein together with 1 g paracetamol, which is used as a marker for gastric emptying.

During a postprandial period of 6 hours parameters of protein metabolism (e.g. amino acids in plasma and urine), glucose metabolism (plasma glucose, serum insulin) and gastric emptying rate (based on plasma paracetamol) are analysed. Furthermore, subjective hunger/satiety and acceptance of the meals are assed using visual analogue scales. Each intervention arm will be separated by a washout period of at least 7 days.
