Blueberries are a staple in healthy diets, celebrated for their vibrant flavor and impressive nutrient profile. Whether you enjoy them fresh in the summer or frozen year-round, these tiny berries offer a powerful dose of vitamins, minerals, and antioxidants for relatively few calories. For those counting calories, knowing the precise nutritional information is essential. This guide breaks down the calorie content and other important nutrients in a 150 gm serving of blueberries.
The Calorie Count: Fresh vs. Frozen Blueberries
When examining the calorie count, it's important to consider whether the blueberries are fresh or frozen, as there can be minor differences due to processing.
Fresh Blueberries
Based on several nutritional databases, a 150-gram serving of fresh, raw blueberries typically contains 86 calories. This portion size is slightly larger than a standard U.S. cup, which is 148 grams and contains approximately 84 calories. This low calorie count makes blueberries an excellent choice for a snack or addition to meals for those managing their weight. The calories are primarily derived from the fruit's natural carbohydrates.
Frozen Blueberries
For unsweetened frozen blueberries, the calorie content is slightly lower. A 150-gram serving provides around 77 to 79 calories. This minimal difference is largely due to variations in water content and berry variety. The nutritional integrity, including the antioxidant levels, remains largely intact during the freezing process, so frozen berries offer a virtually identical health benefit for slightly fewer calories.
