REVAMP Study

Proteins, proteins, proteins: we see the promotion of eating enough of them everywhere. We already know that added proteins can have an effect on our digestion. But what happens while consuming proteins that are naturally present in foods? And how do these proteins affect our hormonal system?

To answer those questions, we are looking for you. For 2 periods of 2 weeks, you will eat free breakfast, lunch, and dinner at the research location (Helix) on work days within a time span of 7 weeks. For the weekends, we provide you with food to eat at home.

Digestion, hormones and proteins

After the consumption of food, carbohydrates, fats, and proteins are broken down in the stomach and intestines and then absorbed. The composition of added proteins in food can influence these digestion processes. However, less is known about proteins that are naturally present in foods. Therefore, with the REVAMP study, we aim to investigate whether proteins naturally present in food affect digestion and other physical responses such as endocrine responses.

Timeline

This study will take place from October 2023 to November 2024. The study lasts for 7 weeks, with a preceding information session and screening session. Both sessions will be scheduled in consultation with you. During a study period of 7 weeks, you will eat breakfast, lunch, and dinner at the research location (Helix) on work days for 2 x 2 weeks. On the weekends, you will receive pre-packed foods to consume your meals at home. Your body composition will be measured multiple times during the 7 weeks, and blood will be drawn a total of 3 times. Do you want to contribute to gaining more insights in protein digestion?
