The blueberry is a small, round berry that is purplish, almost black, in colour. It has a mild, sweet and slightly tart taste, although this can vary depending on the variety of blueberry, as can its size.
The blueberry is a low calorie fruit rich in tannins, vitamins and micronutrients. Its antioxidant properties make it a well-known berry that is frequently eaten as a "functional food". Anti-inflammatory virtues are sometimes attributed to it, along with positive effects on sight and memory.
