Frozen red and green grapes essentially have the same nutritional value despite a difference in color. Many nutritionists recommend frozen grapes as a healthy snack as they provide protein, calcium and vitamin C without high fat, cholesterol or sodium. Kids especially love the icy cold grapes, though they could pose a choking hazard for very young children.

Minerals

One cup of frozen red or green grapes contains 1.2 grams of protein, 16 milligrams of calcium, 0.58 milligrams of iron, 0.3 milligrams of niacin and 0.1 milligrams of riboflavin. With more than 1 gram of protein, the grapes provide 3 percent of your daily required value.

Vitamins

A serving of frozen red or green grapes provides minimal vitamin nutrients. One cup of red or green grapes contains 106 international units of vitamin A, 17.2 milligrams of vitamin C and 0.3 international units of vitamin E.

Fats, Cholesterol and Sodium

Nutritionists often suggest red and green grapes as a healthy snack in part because they contain very little fat or cholesterol. One cup of green or red frozen grapes contains only 0.3 grams of fat. Of this fat, 0.1 grams comes from saturated fat and the remainder comes from polyunsaturated fat. Frozen grapes do not contain any cholesterol or sodium.

Calories and Antioxidants

A cup of frozen grapes contains 110 calories, with only 4 calories from fat. The one major difference between frozen red versus green grapes comes in the antioxidants found in red grapes. Frozen red grapes contain trace amounts of resveratrol, an antioxidant linked to preventing heart disease.
