SERVING SIZE

Calories by portion and serving weight

PHOTO LOGGING

How to log raw starfruit 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.

  1. 01

    Match the exact reference state: Carambola, (starfruit), raw.

  2. 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.

  3. 03

    Log oil, sauce, sweetener, salt and recipe ingredients separately.

  4. 04

    Use a separate record when preparation changes the food state.
