If you’re searching for 100 grams blueberries calories, the short answer is about 57 calories for raw blueberries. That makes them a low-calorie fruit option with a lot of volume for the calories.
Blueberries also bring fiber, vitamin C, and natural plant compounds called anthocyanins, which give them their deep blue color. If you’re logging meals or balancing a training plan, knowing the calories per 100 grams can make portion tracking much easier.
How many calories are in 100 grams of blueberries?
According to USDA FoodData Central, 100 grams of raw blueberries contains about 57 calories. That amount is roughly a small bowlful or a little over 1/2 cup, depending on berry size.
For context, 100 grams is a useful reference because food labels and nutrition databases often use it as a standard comparison amount. It helps you compare blueberries with other fruits more accurately than guessing by handfuls or cups.
What’s in 100 grams of blueberries besides calories?
A 100-gram serving of raw blueberries is not just low in calories; it also provides about 14.5 grams of carbohydrate, 2.4 grams of fiber, and around 0.7 grams of protein. It also has small amounts of fat.
Blueberries are a good source of vitamin C and manganese, and they contain anthocyanins, the antioxidants linked to the fruit’s blue-purple color. In practical terms, that means you get a nutrient-dense snack without a big calorie load.
Blueberries: portion sizes and calorie comparisons
A common serving is 1 cup of blueberries, which weighs roughly 148 grams and has about 84 calories. So if you eat 100 grams, you’re getting a bit less than a cup and a little under 60 calories.
If you compare them with more calorie-dense snacks, blueberries are easy to fit into a weight-conscious diet. They can also add sweetness to yogurt, oatmeal, or smoothies without adding much sugar or fat from the fruit itself.
How to use this number for tracking meals and goals
If you track calories or macros, weigh blueberries in grams when possible. That’s the most accurate way to log fruit, especially if the berries are large, small, or mixed with other fruit.
When meal photos or visual estimates are your only option, it helps to remember that blueberries are very light and airy in a bowl. A cup can look smaller than you expect, so gram-based tracking is usually more reliable. If you’re also tracking workouts, Fitnit can help with automatic rep counting and form feedback during training, which can make it easier to stay consistent overall.
