Delicious berry. Blueberries are a popular berry, known far and wide for their dark blue colour, provided by the pigment anthocyanin. This fruit grows on bushes and, like cranberry, is considered a wild berry. Blueberries have a high content of manganese, vitamin C and fibre, and one cup (145 g) of fresh blueberries contains only 81 calories. Blueberries played an important role in the Native American diet, and the first settlers did not take to them quickly due to their original sour taste. They only became popular in the 20th century with the development of the American blueberry, with its sweet and meaty properties. Today, the USA is the world's largest blueberry producer. *Source: Faostat, Helgi Analytics
