If you’re looking up calories in 14g blueberries, the short answer is about 8 calories for raw blueberries. That estimate comes from USDA nutrition data for blueberries at roughly 57 calories per 100 grams.
It’s a very small serving — about 1 tablespoon plus a little extra, depending on berry size. Even though the calorie count is low, blueberries still provide carbs, fiber, and micronutrients, so they can fit well in snacks, yogurt, oatmeal, or post-workout meals.
Calories in 14g blueberries
Using standard USDA data for raw blueberries, 14 grams contains about 8 calories. The exact number can vary slightly by berry variety, ripeness, and whether the blueberries are fresh or frozen, but 8 calories is a solid estimate for plain raw blueberries.
If you are tracking food intake closely, it helps to think in grams rather than cups. Blueberries are light and watery, so a small-looking portion may still weigh very little. A kitchen scale gives the most accurate result.
What 14g of blueberries provides
A 14g portion of raw blueberries is mostly water and carbohydrate. It contains only a trace of protein and fat, plus a small amount of fiber. While the serving is too small to deliver a large nutrient dose, blueberries do contribute vitamin C, vitamin K, and plant compounds called anthocyanins.
For people watching calories, blueberries are a high-volume, low-calorie fruit option. They can add sweetness and texture without the calorie load of many packaged snacks or desserts.
How to estimate blueberry calories accurately
The easiest way to estimate calories is to use weight. USDA raw blueberries are about 57 calories per 100 grams, so 14 grams works out to just under 8 calories. If your blueberries are frozen without added sugar, the calorie count is usually similar to fresh blueberries by weight.
If blueberries are in a sweetened product — like pie filling, dried blueberries with sugar, or a fruit blend with syrup — calories can be much higher. Always check the label for added sugar and serving size.
Good ways to use a 14g serving
A 14g serving is small, but it can be useful for flavoring without adding many calories. Try it as a topping for plain yogurt, mixed into cottage cheese, or added to a smoothie when you want just a hint of fruit sweetness.
If you’re also tracking exercise and meals, a tool like Fitnit can help keep things consistent by reading meal photos for macros and counting reps from your phone camera. That can make it easier to match your food intake with your training routine.
Tips
- Weigh blueberries once or twice to learn what 14g looks like in your hand or bowl.
- Use raw or unsweetened frozen blueberries if you want the lowest-calorie option.
- Check labels on dried blueberries and fruit mixes, since added sugar can change calories a lot.
- If you log food often, save common portions like 14g, 28g, and 50g for faster tracking.
- Pair blueberries with protein, such as yogurt or cottage cheese, to make the snack more filling.
