What research has been done on tart cherries?

Although anthocyanins, which are also found in blueberries and other purplish-red fruits and vegetables, are known to be powerful antioxidants, no studies have looked at whether cherries--tart or sweet-can relieve symptoms of arthritis, gout, or diabetes outside the lab.

  • A small randomised controlled trial in the British Journal of Sports Medicine examined the effectiveness of a tart cherry juice blend in preventing symptoms of exercise-induced muscle damage. Fourteen male college students drank 12 fl oz of a cherry juice blend or a placebo, twice per day for eight consecutive days. Strength loss was significantly lower in people taking the cherry juice (4%) compared with the placebo (22%). Pain was also significantly lower in people taking the cherry juice.

  • Jill M. Tall, Ph.D., research fellow at Johns Hopkins, was the lead researcher of a study that tested the effectiveness of orally administrated anthocyanins from tart cherries on inflammation-induced pain in rats. The results of the study suggested that tart cherry anthocyanins may have a beneficial role in reducing inflammatory pain.
