Per multiple nutritional databases, this small portion typically contains about 20–21 calories. The macronutrient distribution is heavily skewed towards carbohydrates, with a trace amount of protein and fat.
Calories
At just over 20 calories, a 1/4 cup of blueberries is a very low-calorie fruit option. The calories primarily come from carbohydrates, specifically the natural sugars present in the fruit. This makes them an excellent choice for individuals managing their calorie intake for weight management, as they provide flavor and nutrients without contributing significantly to your daily total.

Blueberries, like most fruits, are not a significant source of protein. A 1/4 cup serving typically contains only around 0.2 to 0.3 grams of protein. For those looking to increase their protein intake, it is necessary to pair blueberries with other protein-rich foods, such as Greek yogurt, cottage cheese, or a protein-rich smoothie.
Other Key Nutrients
Beyond the primary macronutrients, a 1/4 cup of blueberries also offers valuable micronutrients and health-promoting compounds. This small serving contains about 1 gram of dietary fiber, which aids in digestion and helps promote a feeling of fullness. Blueberries are also a rich source of antioxidants, particularly anthocyanins, which are responsible for their deep blue color and powerful health benefits. This serving also provides small amounts of vitamins C and K, and manganese.
