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.

Potassium
198 mg per 100 g in the selected USDA record.

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 red radish
Selected reference.
Pickled radish
Use the exact pickled product or recipe.
Cooked radish
Use a cooked-state record or recipe.
Other radish variety
Use a variety-specific source when available.
PRACTICAL CONTEXT
How raw red radishes 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 19.6 kcal per 100 g, the 50 g example is 9.8 kcal.
Fibre check
The selected record lists 1.31 g fibre per 100 g.
Protein check
The selected record lists 0.656 g protein per 100 g.
Best logging move
Use edible raw weight; the source supplies no household measure, so all non-100-g examples are explicit calculations.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep raw radishes according to seller or package guidance.
After opening or cutting
Keep cut radish protected and appropriately chilled.
Prepare
Wash under clean running water and trim damaged areas before use.
Safety boundary
Discard mouldy, slimy or deeply spoiled radishes; this nutrient record sets no storage duration.
PHOTO LOGGING
How to log raw red radishes 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: Radishes, red, 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
Radishes, red, 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.
