SERVING SIZE
Calories by portion and serving weight

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.
Mature, boiled, no salt
Selected reference.
Edamame
Green soybeans are a separate food state.
Dry roasted
Use the roasted record and match salt state.
Sprouted or fermented
Choose the exact product rather than this boiled-bean record.
PRACTICAL CONTEXT
How cooked mature soybeans 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 172 kcal per 100 g, the 10.7 g example is 18.4 kcal.
Fibre check
The selected record lists 6 g fibre per 100 g.
Protein check
The selected record lists 18.2 g protein per 100 g.
Best logging move
Use cooked mature-bean weight and keep edamame, roasted and fermented soy products separate.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep dry soybeans sealed in a cool, dry place.
After opening or cooking
Keep cooked soybeans covered and chilled when not being served.
Prepare
Follow package soy-allergen guidance and current sprout guidance where relevant.
Safety boundary
The nutrient record does not establish storage duration; follow current local guidance for cooked legumes.
PHOTO LOGGING
How to log cooked mature soybeans 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: Soybeans, mature cooked, boiled, without salt.
- 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.
