Like most berries, blackberries are low in calorie — one cup has only 62 calories. They're nutritious as well. That same cup of blackberries has 42 milligrams calcium and 233 milligrams potassium. It's also a good source of iron, zinc, magnesium, vitamin C, and folate. Blackberries are virtually fat-free, plus they contain some phytochemicals called anthocyanins in the purple pigment.
Fresh blackberries are available in the produce section of the grocery store. Blackberries are tasty just as they are, without anything added. But, you can combine them with strawberries and blueberries. Layer the berries with a light whipped topping for a delicious parfait.
Use blackberries and a little honey as a topping for oatmeal at breakfast time, or add them to Greek yogurt for dessert. You can also serve them with a scoop of vanilla ice cream or frozen yogurt.
