57 kcal / 100 gNutrition values describe a reference food state, not every individual item. Variety, water content, preparation and portion weight can change the estimate.
THE NUMBERS
Blueberry nutrition facts per 100 g
The table below uses the reference state shown at the top of this page. Keeping one gram basis makes it easier to compare foods before translating the values to the portion you actually ate.
Source: USDA FoodData Central SR Legacy record 171711. Values may be rounded for readability.
SERVING SIZE
Calories by portion and serving weight
Words such as “small,” “medium,” “half” and “one piece” are convenient but imprecise. Grams make the estimate reproducible, particularly when natural foods vary in size.
MACROS
Carbohydrate, protein and fat explained
Carbohydrate
Most blueberry calories come from carbohydrate, including naturally occurring sugars and fibre.
Protein
Blueberries contain very little protein and work best as the fruit component of a snack or meal.
Fat
Plain blueberries are naturally very low in fat; granola, cream, pastry and nut toppings must be counted separately.
MORE THAN CALORIES
Fibre, vitamins and minerals
One food does not need to provide every nutrient. These are the characteristics most useful for understanding where blueberry fits in a varied eating pattern.
Fibre
Raw blueberries provide 2.4 g of fibre per 100 g.
Vitamin C
The reference amount contributes 9.7 mg of vitamin C.
Anthocyanins
The blue-purple pigments are plant compounds not fully represented in a basic nutrition panel.
Potassium
Blueberries contribute some potassium but are not among the most concentrated sources.
FOOD STATE MATTERS
How preparation changes the nutrition estimate
A reliable calorie entry should describe the food you actually ate—not merely a food with a similar name.
Frozen unsweetened
Plain freezing does not add calories, although serving weight and texture can differ.
Sweetened frozen
Added sugar creates a separate product and must be included.
Dried
Dried blueberries are far more concentrated by weight and are often sweetened.
Baked
Muffins, pancakes and pies are complete recipes, not plain blueberries.
PRACTICAL CONTEXT
How blueberry can fit different goals
There is no universal “good” or “bad” food. Portion, frequency, the rest of the meal, preferences and individual health needs all matter.
Fruit intake
Blueberries are an easy way to add fruit to breakfast, snacks and desserts.
Fibre goals
They make a useful contribution alongside other fibre-rich foods.
Calorie planning
Weigh larger bowls because visual handfuls vary.
Balanced snacks
Add a suitable protein source when more satiety is useful.
QUALITY & SAFETY
How to choose, store and prepare it
Choose
Avoid containers with mould, leaking fruit or widespread collapse.
Refrigerate
Keep fresh blueberries cold and reasonably dry.
Wash
Rinse gently under running water before eating.
Freeze
Freeze in measured portions when easy later logging matters.
PHOTO LOGGING
How to log blueberry more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Confirm whether the blueberries are fresh, frozen, dried, canned or sweetened.
- 02
Use edible grams when possible; cups and handfuls vary.
- 03
Log sugar, syrup, granola, cream and other additions separately.
- 04
For oatmeal, yogurt bowls, muffins or smoothies, log the blueberries and other ingredients separately.
