Why are blueberries so healthy?

Blueberries are flowering plants that produce blue berries, and are native only to North America. When mature, the berries have a sweet taste and varying acidity. The blue pigment in blueberries is anthocyanin. Blueberries also have antioxitants (molecules that prevent oxidation of cells, which prevents damaging of cells over time) and other phytochemicals (good stuff from plants), which help reduce the risk of cancer and other ailments. Some research has indicated that blueberries also help prevent cognitive decline and Alzheimers.
