Top Health Benefits of Black Grapes
Black grapes are not just delicious and juicy; they are also packed with essential nutrients that can support your overall health. Rich in antioxidants, vitamins, and natural plant compounds, black grapes offer several benefits when included in your daily diet. Here’s a look at the key health benefits of black grapes:
1. Black Grapes Are Delicious and Nutritious
Black grapes are not only delicious but also packed with essential nutrients that benefit your overall health. A one-cup serving (138 grams) of seedless black grapes provides around 90 calories, 24 grams of carbohydrates, 1 gram of fiber, 1 gram of protein, and 1 gram of fat. They are an excellent source of vitamin C (17% of the Daily Value) and vitamin A (11% of the DV), along with small amounts of iron (2% of the DV).
