Whether dipped into melted chocolate, baked into a pie, sliced onto cold cereal or eaten straight out of the pint, strawberries are a low-calorie source of essential nutrients. They're particularly rich in vitamin C.
According to the Centers for Disease Control and Prevention, 1/2 cup of sliced strawberries is a serving, and each serving has just 25 calories, none of which come from fat. If you eat 2,000 calories each day, one serving of strawberries is just over 1 percent of your day's caloric total.
Carbohydrate, Fiber and Protein
Each serving of strawberries contains 6 g of carbohydrate, 4 g of which are from sugars. The remaining 2 g come from dietary fiber. A serving of strawberries gives you 7 percent of your recommended daily value of fiber. It also contains 1 g of protein.
Vitamin C and Potassium
Each 1/2 cup of strawberries gives you 80 percent of your recommended daily value of vitamin C. Strawberries are also a good source of potassium, with 127 mg in each 1/2 cup, according to the U.S. Department of Agriculture's National Nutrient Database.
