Along with protein, blackberries are packed with other nutrients. According to the Cleveland Clinic, they are an excellent source of antioxidants, which can help protect your body against oxidative stress and reduce the risk of chronic diseases. Plus, a cup of blackberries contains about 7.6 grams of dietary fiber, which can improve your digestive health and prevent gastrointestinal problems. Blackberries are also rich in essential vitamins and minerals.
They contain a healthy dose of vitamin C, which is great for your immune system and skin health. Additionally, they have vitamin K, which is necessary for blood clotting, and manganese, a mineral that is vital for bone health and metabolism (per Healthline). Blackberries are also a smart choice for those watching their calorie and carbohydrate intake as they are relatively low in calories, and their carbohydrates are mostly from fiber, which has minimal impact on blood sugar levels.
The fiber and antioxidants in these tasty berries can also reduce the risk of heart disease. Fiber helps to keep your cholesterol levels in check (per Mayo Clinic), while antioxidants protect your arteries from damage and inflammation, according to the American Heart Association. A 2012 study published in the Journal of Agricultural and Food Chemistry showed that the antioxidants in berries can help improve cognitive function and memory.
