Where the calories come from
Calories come from three macronutrients: protein and carbohydrate at 4 kcal per gram, fat at 9 kcal per gram. For blueberries (raw) the split is:
- Protein: 0.7 g × 4 = 3 kcal — 5% of calories
- Carbohydrates: 14.5 g × 4 = 58 kcal — 91% of calories
- Fat: 0.3 g × 9 = 3 kcal — 5% of calories
- Most of the energy in blueberries (raw) comes from carbohydrate (91% of calories).
- 10 g of its carbohydrate per 100 g is sugar.
- For 200 kcal you can eat about 350 g.
What actually changes the number
Blueberries are dense enough to be worth measuring by the cup rather than the handful — a heaped cup is around 150 g and 85 kcal. Dried blueberries are a different food entirely, roughly five times the calories by weight.
How accurate are these numbers?
The values on this page are reference averages from the USDA FoodData Central database (SR Legacy release), measured on samples of blueberries as sold and prepared in the United States. Your portion will differ: produce varies by variety and ripeness, meat by cut and trim, and anything cooked by the fat and water it gained or lost.
For most foods the per-100 g figure is reliable to within about 10%. The larger uncertainty is almost always the weight of what is on your plate and the cooking fat you cannot see — the two things worth checking before you worry about the database.

Can I track blueberries by taking a photo?
Yes. A photo calorie app like Wellix identifies blueberries on the plate and estimates the portion from the image. The estimate is most accurate when you confirm the weight or the count, and tell the app about anything the camera cannot see — cooking oil, butter, dressings and sauces.
