Blackberries are part of the bramble family. Spinach, raisins, apples, plums and grapes, blackberries are rich in bioflavonoids and Vitamin C, but other nutritional benefits include a very low sodium count and having only 62 calories to a cup. The dark blue colour ensures blackberries have one of the highest antioxidant levels of all fruits. Antioxidants, well-known for lowering the risk of a number of cancers, are a huge bonus, but be aware the berries are best consumed in their natural state to get the full benefits. The berries are known by a variety of names, which include brambleberries, bramble, dewberry, thimbleberry and lawers.
