Calories in Blueberries

About Blueberries

Blueberries are consistently ranked among the most nutrient-dense foods per calorie. A full cup of fresh blueberries contains only 84 calories yet provides a wealth of antioxidants, vitamins, and fiber that make them one of the healthiest additions to any diet.

The standout feature of blueberries is their anthocyanin content — the natural pigments that give blueberries their deep blue color. Anthocyanins are powerful antioxidants linked to improved brain function, reduced inflammation, lower blood pressure, and better cardiovascular health. In fact, blueberries have one of the highest antioxidant capacities of any commonly consumed fruit.

From a macronutrient standpoint, blueberries are primarily carbohydrates (21g per cup), with about 4 grams of fiber and 15 grams of natural sugar. The fiber slows sugar absorption, giving blueberries a relatively low glycemic impact despite their sweetness.

Blueberries are incredibly versatile — add them to oatmeal, smoothies, yogurt, salads, or eat them straight from the container. BasedHealth can scan your exact serving to track calories precisely.
