The dark blue color of blackberries ensures they 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. Consumption of blackberries can also help to promote the healthy tightening of tissue, which is a great non-surgical procedure to make skin look younger. Prolonged consumption also helps keeps your brain alert, thereby maintaining clarity of thought and good memory. Much like 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 per cup. The blackberry is small in size but large in nutritional facts!
