As a recent Newsweek article said “The day when doctors say – ‘Take 10 cherries and call me in the morning’ – may not be far off.” The secret is in the pigments that give tart cherries their rich red / black hue. They belong to a class of natural dyes called anthocyanins. These compounds are being called “Mother Nature’s all-natural agents.” In addition to the antioxidants, tart cherries are rich in two important flavonoids – isoqueritrin and queritrin. According to leading researchers, queritrin is one of the most potent agents ever discovered. Consuming it in foods, such as tart cherries, is like unleashing inside your body an entire army of agents.
