Summary

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.

Detailed description

Rationale: There is a growing interest in plant-based alternatives for bovine milk. However, these plant-based drinks are not a complete nutritional substitute for bovine milk, especially when focusing on the protein content and quality of these products. Knowledge on the effects of protein quantity and quality of plant based drinks on postprandial plasma responses and gastric behavior compared to bovine milk is lacking. Objective: To explore the effect of protein quantity and quality of protein in plant-based drinks. In addition, gastric behavior will be examined and compared to that of bovine milk. Study design: Single-blind randomized cross-over study with three treatments. Study population: 12 healthy normal-weight males, aged 18-45 y. Intervention: After an overnight fast, participants will drink cow's milk, or a plant-based drink. Gastric behavior will be monitored using Magnetic Resonance Imaging (MRI). Blood samples will be collected for plasma metabolomic analyses. In addition, wellbeing will be assessed.
