Milk and Plant Protein Digestion
The goal of this study is to explore the effect of protein quantity and quality in plant-based drinks. Healthy normal-weight males aged between 18 and 45 years will be included in the study.

The main objectives are to examine the differences in postprandial amino acid profiles, and to examine differences in gastric behavior between cow's milk and plant based drinks.

Participants will visit after an overnight fast three times and have blood draws before and after consumption one of the study drinks. There will be MRI scans of the stomach before and after consumption of the drink to assess gastric behavior.
