How many calories are in 100 grams of blueberries?

A 100-gram serving of raw blueberries has about 57 calories, based on USDA food data. For most people, that is roughly 3/4 cup of berries, though the exact cup-to-gram conversion varies a bit depending on berry size and how tightly they’re packed.

If you’re tracking intake closely, the best way to think about blueberries is by weight rather than volume. A small handful can look bigger or smaller than expected, but 100 grams is a precise amount and keeps calorie estimates consistent.

Blueberries nutrition per 100 grams

In addition to calories, 100 grams of blueberries typically provides about 14.5 grams of carbohydrate, 2.4 grams of fiber, about 10 grams of natural sugar, roughly 0.7 grams of protein, and less than 0.5 grams of fat. They also contribute vitamin C and manganese.

The fiber is one of the most useful parts nutritionally. It helps blueberries feel more filling than many other foods with a similar calorie count, especially when paired with protein or fat such as Greek yogurt, cottage cheese, nuts, or chia seeds.

Do frozen, dried, or sweetened blueberries have the same calories?

Fresh and unsweetened frozen blueberries are usually very similar in calories because freezing does not add sugar or fat. The biggest difference is texture, not energy content.

Dried blueberries are a different story. Removing the water makes the calories much more concentrated by weight, and many dried blueberries also contain added sugar. Sweetened products, blueberry snacks, and blueberry muffins can be far higher in calories than plain berries.

How to use 100 grams of blueberries in a meal plan

If you want a realistic fruit portion for weight management or macro tracking, 100 grams is a good benchmark because it is satisfying without being calorie-heavy. It works well as a topping, a snack, or a mix-in for breakfast meals.

If you’re pairing blueberries with workouts or trying to keep your meals consistent, simple tracking habits help. Fitnit can be useful for the exercise side of that routine with automatic rep counting and AI form analysis, while blueberries can be tracked by weight or meal photo when you want a quick nutrition estimate.

Tips

• Weigh blueberries once or twice to learn what 100 grams looks like in your usual bowl.
• Choose unsweetened frozen blueberries if you want convenience without changing calories much.
• Pair blueberries with protein, like yogurt or a protein shake, to make the snack more filling.
• Check labels carefully on dried or sweetened blueberry products because calories can rise fast.
• If you are logging meals, record blueberries by grams instead of cups for better accuracy.
