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.

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 reference.
Grilled
Use final weight and log oil separately.
Salad
Log dressing, cheese and nuts.
Mixed greens
Use the exact mix label or weigh components.
PRACTICAL CONTEXT
How raw radicchio 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 26.4 kcal per 100 g, the 50 g example is 13.2 kcal.
Fibre check
The selected record lists 2.11 g fibre per 100 g.
Protein check
The selected record lists 1.31 g protein per 100 g.
Best logging move
Use raw leaf weight and keep cooking fat or salad additions separate.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep radicchio chilled and reasonably dry.
After opening or cutting
Keep cut leaves covered in a clean container.
Prepare
Rinse before eating and use clean utensils.
Safety boundary
Discard slimy or extensively spoiled leaves; the nutrient record does not establish storage duration.
PHOTO LOGGING
How to log raw radicchio 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: Radicchio, 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, while explicitly labelled gram examples are calculated.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.

SOURCES & METHOD
Where these numbers come from
Radicchio, raw, per 100 g edible portion. Numeric nutrition claims use the nutrition-reviewed local USDA record. Named portion claims use source-held weights; explicitly labelled gram examples are calculations from the per-100-g record. The nutrient record does not establish storage duration, clinical advice or food-safety limits; use package directions and current authoritative guidance where relevant.
