Calories in Strawberries

How Many Calories Are in Strawberries?

Strawberries are one of the lightest fruits available. One cup of sliced strawberries contains about 53 calories, and a single medium berry is only about 4 calories. By weight, strawberries come in at roughly 32 calories per 100 grams, on par with watermelon and among the lowest of any common fruit.

They are almost entirely carbohydrate, but with a high water and fiber content that keeps both calories and sugar very low. That combination makes strawberries a favorite for anyone watching calories or carbs while still wanting something sweet.

Plain frozen strawberries match fresh. Watch for sweetened frozen strawberries in syrup and strawberry jam, which add significant sugar and calories.

Are Strawberries Low in Sugar?

Strawberries are among the lowest-sugar fruits you can choose. A full cup contains only about 8 grams of natural sugar — less than a single banana and far below grapes or mango. Their generous fiber, about 3 grams per cup, further softens the impact on blood sugar. This makes strawberries a smart pick for low-carb, diabetic-friendly and weight-loss diets, where you can enjoy a satisfying portion without the sugar load of sweeter fruits.

Macros and Nutrition in Strawberries

A cup of sliced strawberries provides about 13 grams of carbohydrate, 3.3 grams of fiber, 8 grams of natural sugar and 1 gram of protein, with no fat. The headline nutrient is vitamin C — a single cup delivers nearly a full day’s requirement, more than an orange by weight. Strawberries also supply manganese, folate and potassium, plus anthocyanins and ellagic acid, antioxidants tied to heart health. Their high water content, around 91%, is a big part of why they are so light.

Do Strawberries Fit a Healthy Diet?

Strawberries fit virtually every healthy eating pattern. They are low in calories and sugar, high in fiber, water and vitamin C, and versatile enough to top oatmeal and yogurt, blend into smoothies or stand alone as a snack. As a dessert swap, a bowl of strawberries satisfies a sweet tooth for a fraction of the calories of baked goods. The main thing to avoid is sugar-laden preparations like syrup-packed frozen berries or jam. Fresh or plain frozen, strawberries are about as diet-friendly as fruit gets.
