As of 2015, studies done with cherries, cherry juice and cherry extract indicate the fruit's efficacy in reducing recurrent attacks of gout, states the Arthritis Foundation. A 2012 study at Boston University Medical Center claims that eating 10 cherries daily reduces flares by up to 50 percent.
A study from the Robert Wood Johnson Medical School reports that gout patients who consumed a tablespoon of tart cherry extract twice daily for four months saw incidences of gout flares reduced by half. Boston University researchers say that the pigment anthocyanin, which naturally occurs in cherries, blueberries and raspberries, is responsible for the berries’ anti-inflammatory and antioxidant properties, notes the Arthritis Foundation. The pigments are particularly potent in tart cherries and work by reducing uric acid, which causes gout.
