Frequently Asked Questions (FAQ)

How many calories are in a cup of blueberries?

One cup of fresh blueberries (about 148 grams) contains approximately 84 calories. That cup provides 21 grams of carbohydrates, 15 grams of natural sugar, 3.6 grams of fiber, and 36% of your daily vitamin K. Blueberries also deliver 24% of your daily vitamin C per cup.

Are blueberries a superfood?

While "superfood" is not an official scientific term, blueberries come close to earning that label. They rank among the highest of all common fruits and vegetables in antioxidant capacity. Research links regular blueberry consumption to improved memory, lower blood pressure, reduced LDL cholesterol oxidation, and better insulin sensitivity.

How do blueberries compare to other berries in calories?

Blueberries are moderate in calories compared to other berries. Per 100 grams, strawberries have 32 calories, raspberries have 52, blueberries have 57, and blackberries have 43. While blueberries have slightly more calories and sugar, they also have a significantly higher antioxidant content than most other berries.

Are blueberries good for your brain?

Yes. Multiple studies show that blueberry consumption improves cognitive function and may delay age-related mental decline. The anthocyanins in blueberries cross the blood-brain barrier and accumulate in brain regions involved in memory and learning. Research suggests that eating half a cup of blueberries daily can produce measurable cognitive benefits.

Do dried blueberries have more calories than fresh?

Yes, significantly more. Dried blueberries contain about 340 calories per 100 grams compared to 57 calories per 100 grams for fresh blueberries — roughly six times more calorie-dense. The drying process removes water, concentrating the sugars and calories. Many commercial dried blueberries also have added sugar. Always check the label and be mindful of portion sizes with dried fruit.
