USDA calories for blueberries per 100g

According to USDA FoodData Central, raw blueberries provide 57 calories per 100 grams. That serving size also contains about 14.5 grams of carbohydrates, 2.4 grams of fiber, and 10 grams of sugar. Because blueberries are mostly water, the calorie density stays low compared with many other snack foods.

For everyday use, 100 grams is a helpful reference point, but it is not the same as a cup. A cup of raw blueberries is larger than 100 grams, so the calorie total will be higher even though the fruit is still considered light and nutrient-dense.

What 100g of blueberries looks like in real life

A 100-gram portion of blueberries is roughly a small bowlful or about three-quarters of a cup, depending on berry size. If you are tracking intake for weight management, this is a more practical estimate than guessing by handfuls.

If you eat blueberries straight from the container, it helps to remember that small serving changes matter less than with higher-calorie foods. Going from 100 grams to 150 grams only adds about 29 calories if the berries are raw and unsweetened.

Why blueberry calories can vary by form

The USDA number applies to raw blueberries. Frozen blueberries without added sugar are usually very similar. But dried blueberries are much more calorie-dense because the water has been removed, and many dried versions also include added sugar or oil.

Blueberry products like pie filling, jams, smoothies with sweeteners, and yogurt toppings can have a very different calorie profile from plain fruit. Always check the package label or USDA entry for the exact product you’re eating.

How blueberries fit into a healthy diet

Blueberries are popular because they offer fiber and beneficial plant compounds for relatively few calories. That makes them easy to fit into breakfast bowls, snacks, and post-workout meals without adding a lot of energy.

If you’re using blueberries around exercise, pairing them with protein can make a snack more satisfying. Fitnit can also help with workout tracking by counting reps automatically and checking form from your phone camera, which can make home training easier to structure around simple meals like fruit and yogurt.

Tips

• Use 100 grams as your baseline if you want the USDA calorie number: 57 calories for raw blueberries.
• Weigh berries once or twice at home so you can learn what 100 grams looks like in your usual bowl or container.
• Choose unsweetened frozen blueberries if you want a similar calorie count to fresh fruit.
• Check labels carefully on dried blueberries, since added sugar can raise calories quickly.
• If you log meals for weight goals, pair blueberries with protein or fat for better fullness.
