Why cherries are good for you

Anthocyanins in cherries appear to have a marked anti-inflammatory action. Specifically, these compounds seem to be highly effective in treating gout, a condition that causes painful swelling in joints. Last year, a Boston Medical Center study reported that eating cherries reduces gout attacks by 35%. Cherries are also one of the few food sources of the hormone melatonin, which regulates sleep patterns.
 A study published in 2011 in the European Journal of Nutrition, reported that eating tart montmorency (or morello) cherries significantly raised levels of melatonin and improved sleep. Compared to most other fruits, cherries are low in sugar, which makes them an ideal choice for people who want to lose weight.
