Cherries contain an ingredient that helps the body regulate its natural sleep cycle and potentially get more rest, researchers say.
The red fruits contain an antioxidant called melatonin, which is also commonly sold in the form of nutritional supplements.
Melatonin is often used as a sleep aid, but cherries may be a good alternative for helping the body replenish its own supply of the antioxidant, according to Russel J. Reiter of the University of Texas Health Science Center.
“When eaten regularly, tart cherries may help regulate the bodys natural sleep cycle and increase sleep efficiency, including decreasing the time it takes to fall asleep,” he explained.
“And, because cherries are so rich in other antioxidants, such as anthocyanins, you get other important health benefits.”
Previous research at the University of Michigan has also pointed to the potential health benefits of tart cherries, which are sold dried, frozen or in juice.
In rodent studies, animals receiving whole tart cherry powder as part of a high-fat diet did not gain as much weight as those who simply ate a high-fat diet. The rats also had lower cholesterol in their blood.
