A new study shows that eating the recommended five cups of fruits and vegetables a day can lead to better sleep that same night. Researchers found a 16% improvement in sleep quality for those who added more produce to their diet.

The study tracked young adults who recorded their meals and wore sleep monitors. Those who ate more fruits, vegetables, and healthy carbs like whole grains experienced deeper, more restful sleep with fewer wakeups during the night.

Experts say even one day of healthy eating can make a difference. Adding more fruits and vegetables to your meals may be a simple, natural way to improve your sleep.
