Blackberries are an excellent source of vitamin C, vitamin K, manganese, and fiber. Just one cup provides about one third of the daily recommended value of dietary fiber! Blackberries are also extremely high in antioxidants, which can help slow aging and prevent a whole host of chronic diseases. (See more nutrition facts on Self.com.)
Store unwashed berries in the refrigerator. Use quickly, as fresh organic berries are not sprayed with anti-fungal agents. They spoil quickly!
