Optimization of Chrononutrition to Reduce the Risk of Disease in Shift Workers (SHIFT)
Summary
This randomized controlled trial, led by UC San Diego and the Salk Institute, is enrolling night-shift nurses to test whether meal timing can reduce health risks linked to shift work. Participants follow a 10-hour daytime eating window, with one group also receiving a low-glycemic snack during the night shift, while a comparison group continues with usual eating patterns. Researchers will track outcomes such as sleep, alertness, and metabolic health. The study is currently recruiting, with no published results yet.
Why It Matters For Night Shift Workers and Night Owls
Night work can disrupt metabolism and increase risks for conditions like diabetes and heart disease. This study is designed to test whether concentrating food intake in the daytime—and limiting overnight eating—can help offset some of those effects. If successful, it could provide night workers with clear, evidence-based guidance on when to eat to better support both short-term energy and long-term health.
