A recent study from the University of Chicago Medicine and Columbia University indicates that increasing the intake of fruits and vegetables may enhance sleep quality.

Published in the journal 'Sleep Health' in June 2025, the research highlights the correlation between daily dietary choices and sleep patterns, particularly focusing on sleep fragmentation.

To assess sleep patterns, the study utilized objective wrist monitors, which measured sleep fragmentation—disruptions that occur during sleep.

Healthy young adults participated by tracking their daily food intake through an app while also wearing wrist monitors to measure their sleep.

The findings revealed that consuming more fruits, vegetables, and healthy carbohydrates like whole grains led to deeper and less interrupted sleep, underscoring the importance of diet on sleep health.

Co-senior author Esra Tasali, MD, emphasized that dietary changes can serve as a natural and cost-effective method for improving sleep quality.

Remarkably, significant improvements in sleep quality can occur within just 24 hours of making dietary modifications, suggesting a quick response to changes.

The study encourages individuals to make small dietary changes, empowering them to take control of their sleep quality.

This research marks the first time a temporal context has linked diet to sleep patterns, providing new insights into how our food choices affect our rest.

The study received funding from multiple National Institutes of Health grants, highlighting the importance of this research in understanding sleep health.

Future studies are needed to further explore the causation and biological mechanisms behind the observed effects of diet on sleep quality.
