THE NUMBERS
Blackberry 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.

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.
Raw
Selected generic reference.
Wild
Mapped separately from common raw blackberries.
Frozen
Use the unsweetened frozen record when it matches.
Canned
Use the syrup-pack record and include its liquid as eaten.
PRACTICAL CONTEXT
How blackberry 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.
Portion math
At 43 kcal per 100 g, the 50 g example is 21.5 kcal.
Fibre check
The selected record lists 5.3 g fibre per 100 g.
Protein check
The selected record lists 1.39 g protein per 100 g.
Best logging move
Weigh the berries and switch records when they are frozen, canned or part of a sweetened recipe.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep fresh blackberries dry and chilled.
After opening or cutting
Rinse shortly before eating and drain gently.
Prepare
Remove leaking or mouldy berries so spoilage does not spread.
Safety boundary
The nutrient record does not establish storage duration; follow current produce-safety guidance.
PHOTO LOGGING
How to log blackberry 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
Match the exact reference state: Blackberries, raw.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
