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.
Common guava, raw
Selected reference.
Strawberry guava, raw
Mapped as a separate variety.
Guava juice or nectar
Not represented by the selected whole-fruit record.
Guava paste or canned guava
Not represented by the mapped raw-fruit records.
PRACTICAL CONTEXT
How guava 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
68 kcal per 100 g becomes 37.4 kcal for the 55 g example.
Fibre check
The selected record lists 5.4 g fibre per 100 g.
Protein check
The selected record lists 2.55 g protein per 100 g.
Best logging move
Use the edible portion and switch records when the fruit is processed into nectar, paste or another sweetened product.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep ripe guava chilled and protected from crushing.
After opening or cutting
Cover cut guava in a clean container.
Prepare
Rinse the outside before cutting.
Check before eating
Discard guava with mould, leaking flesh or a fermented off-odour.
PHOTO LOGGING
How to log guava 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: Guavas, common, raw.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portions use weights stored in that 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.
