The jumbo blueberry is larger than standard blueberries and contains slightly more calories, though the difference is minimal. A single jumbo berry typically has about 1 to 2 calories. Examining a serving size, like a cup, offers a more accurate understanding of the calorie content. A half-cup of jumbo blueberries has roughly 11 calories, while a cup of raw blueberries averages about 84 calories. This makes them a healthy snack choice for calorie-conscious individuals.
Nutritional Breakdown of a Jumbo Blueberry
Beyond its low calorie count, the jumbo blueberry is packed with nutrients. Its overall nutritional composition is similar to standard blueberries, differing primarily in size and, consequently, in the nutritional content per berry. They are mostly water, with carbohydrates, mostly simple sugars and dietary fiber, forming the bulk of its caloric content.

Essential Micronutrients
Blueberries are an excellent source of vitamins and minerals. One cup provides a significant portion of daily Vitamin C, vital for immune function, and Vitamin K, important for blood clotting and bone health. They also contain manganese, which aids in bone development and nutrient metabolism. Their most significant components are the antioxidants, particularly anthocyanins, which give them their deep blue color and provide powerful health benefits.
Calorie Tracking: A Weight-Based Approach
Because the size of blueberries varies, the most reliable calorie-tracking method is based on weight or a standardized volume. This method avoids the inaccuracies of counting individual berries.
Examples:
- 100 grams of jumbo blueberries: Approximately 57 calories
- 1/2 cup (18.8g) of jumbo blueberries: Approximately 11 calories
- 1 cup (148g) of raw blueberries: Approximately 84 calories
Health Benefits of Blueberries Beyond Calories
The benefits of eating jumbo blueberries go beyond their low-calorie nature. Their high antioxidant and nutrient content contributes to a range of health benefits.
- Brain Health: Studies suggest that regular blueberry consumption can boost cognitive function and memory, potentially helping protect against age-related cognitive decline.
- Heart Health: Blueberries' antioxidants help lower blood pressure and improve cholesterol levels, particularly by reducing LDL ("bad") cholesterol.
- Digestive Health: The fiber content in blueberries promotes a healthy digestive system, aids in regular bowel movements, and supports gut microbiome diversity.
- Blood Sugar Management: Blueberries have a low glycemic index, leading to a slower rise in blood sugar levels. This, combined with their ability to improve insulin sensitivity, makes them suitable for people managing diabetes.
