Personal Protein Digestion Variability

This study aims to quantify the variation in postprandial AA profiles between (and within) individuals after consumption of a poorly digestible plant protein source (Lucerne) and to compare the variation in postprandial AA profiles between a poorly digestible plant protein source and an easy digestible protein source (whey). The study has a randomised, cross-over, controlled design. Two different treatments, all representing a 20g protein load, will be evaluated on five occasions with a washout period of minimum one week between the test days. On test days, research subjects will receive two different protein sources, in the form of a protein drink, in randomised order; on three test days they will receive a poor-digestible protein source, on two test days an easily digestible protein source. Blood will be collected via a catheter before and up-to four hours after protein consumption. Wellbeing, health complaints or other adverse effects will be collected via short questionnaires during each test day. After each test day gastrointestinal complaints will be collected via an online questionnaire.
