Brief Summary

The goal of this interventional study is to learn about the effects of different proteins (from animals or plants) on the metabolism in healthy, normal weight women between 18-45 year who are not on hormonal birth-control.

The main questions the study aims to answer are:

1. How do different proteins affect biological markers of the metabolism and which protein has the strongest effect?

2. How are the different proteins digested and taken up from our body?

Participants will drink four different shakes on four different study days in a random order. Three of them contain each a different protein and one does not contain protein. Right before drinking the shake and on 11 timepoints after drinking the shake blood samples will be drawn.

Primary Outcome Measures
NameTimeMethod
Release of Growth Hormone0-3 hours after consumption of test drink (on all 4 study days)

The primary outcome is defined as the postprandial release of growth hormone during three hours after oral ingestion of plant-protein test drinks vs. an animal-protein test drink measured as incremental area under the curve. Growth hormone will be measured in blood samples.

Secondary Outcome Measures
NameTimeMethod
Release of Hormones Related to the Somatotrophic Axis0-3 hours after consumption of test drink (on all 4 study days)

We will measure different hormones related to the somatotrophin axis in collected blood samples and investigate if there are differences between different protein-sources.

Kinetics of Amino Acid Uptake0-3 hours after consumption of test drink (on all 4 study days)

We will measure amino acids in collected blood samples to investigate dynamics and kinetics of protein digestion/uptake of different protein sources.
