A different chemical is employed to color different plants. http://www.ag.ndsu.edu/pubs/yf/foods/fn595w.htm Blue/purple fruits and vegetables are colored by natural plant pigments called "anthocyanins." Anthocyanins in blueberries, grapes and raisins act as powerful antioxidants that protect cells from damage. They may help reduce risk of cancer, stroke and Heart disease. Other studies have shown that eating more blueberries is linked with improved memory function and healthy aging. These are some examples of the blue/purple group:
- Blackberries
- Blueberries
- Eggplant
- Figs
- Juneberries
- Plums
- Prunes
- Purple grapes
- Raisins
