Sour Cherries, Wikimedia Commons (Fir0002).

Nutritionally, sour cherries have recently proven to be beneficial for antioxidant and anti-inflammatory properties, discovered from the high levels of anthocyanins found in the red and purple pigments of the cherries themselves. In particular, the Montmorency cherry has proven to have high levels of anthocyanins that assist in reduction of oxidative stress, aging, and cancer. Sour cherries also have high levels of vitamin A (20% of the recommended daily intake in 100 grams) and vitamin C (22% of the recommended daily intake in 100 grams). Although, sour cherries are mostly processed for pie fillings and are not as commonly sold fresh on the market as sweet cherries.
