Both are nutritionally similar in terms of calories, sugar, and vitamins. Red and purple grapes contain resveratrol and anthocyanins — antioxidants linked to heart health and longevity. Green grapes contain catechins and quercetin. If you are choosing for antioxidant content, red grapes have a slight edge, but both are healthy choices.

Are frozen grapes a healthy snack?

Frozen grapes are an excellent low-calorie snack. Freezing does not significantly alter their nutritional content, and the cold temperature slows down eating, naturally promoting portion control. They have a sorbet-like texture that satisfies sweet cravings. About 20 frozen grapes is roughly 70 calories.

Do grapes help with heart health?

Research consistently links grape consumption to improved cardiovascular health. The polyphenols in grapes — especially resveratrol in red grapes — help lower blood pressure, reduce LDL cholesterol oxidation, and improve blood vessel function. Studies show that consuming grapes or grape products daily can reduce systolic blood pressure by 4–6 mmHg.
