Research from John Hopkins Medicine states that blackberries are second only to black raspberries when it comes to overall nutrition. Blackberries are vitamin and nutrient-dense with a high amount of fiber and antioxidants and less sugar than other berries, says a press release from Berry Farms of Compton, CA.
Sweet Karoline is a blackberry variety co-owned by Berry Fresh that is known for its sweet flavor and resistance to red cells, according to the release. Berry Fresh says it is a year-round grower and marketer of premium blueberries, blackberries and raspberries to customers in the Americas.
