Summary

This trial will study the effects of night shift work on the microbiome, and how this may contribute to disease risk.

Who is the study for?
This trial is for non-smoking men aged 40-59 who have been working night shifts or regular day shifts for over 10 years. Participants should be healthy, not on medication, and own an Android smartphone. They can't join if they've traveled across time zones recently, had abdominal surgery, used certain drugs or supplements recently, or have any health issues that could affect the study.
What is being tested?
The study aims to understand how working night shifts affects the microbiome compared to regular day shift workers by examining their behavior, clinical data, and metabolites after eating a standardized meal followed by a glucose test.
What are the potential side effects?
Since this trial involves consuming a standardized meal and undergoing a glucose challenge test rather than testing new medications, side effects are minimal but may include discomfort from blood draws or potential reactions to the meal components.
