Not many fruits are native to North America, but blueberries are one of them (not coincidentally, cranberries are another: the two are related, along with huckleberries.)  Native Americans in various parts of North America are known to have cultivated blueberries.

Blueberries are one of the foods with the highest concentration of antioxidants. They have a moderately low amount of sugar compared to other fruits.

Health Benefits of Blueberries

Blackberries are a good source of vitamin C, vitamin K, and manganese. They also provide very high amounts antioxidant compounds, which may help protect our cells from damage.  Blueberries also contain many other phytonutrients which have healthful effects around our bodies.

Some studies have shown higher levels of antioxidants in wild blueberries and in organically-grown blueberries.

There is some evidence of reduced cancer and heart disease risk from blueberries, as well as many other conditions, although these studies usually involved consuming fairly large amounts of blueberries or drinking blueberry juice.
