Serving Sizes

Serving sizes are labels that help quantify food entries in a user-friendly way. Each serving size is associated with an amount and a base unit (g or ml).

Serving sizes are reference metadata and are not passed as input values to our API endpoints. The same label can represent different amounts depending on the food item. For example, one slice of bread is not necessarily the same amount as one slice of cheese.

Attribute `standard_serving_type`

standard_serving_type indicates the serving size type that is most likely to be selected by users.

This can be used to preselect a serving size and reduce user interaction.

Important behavior:

standard_serving_type can be null or empty.
serving_sizes can also be empty, although this is rare.
A food may have serving_sizes but no standard_serving_type.
It is not possible for standard_serving_type to reference a serving type that does not exist in serving_sizes.
Possible serving size keys are documented here:

Recommended integration behavior:

If standard_serving_type is present, preselect the matching entry from serving_sizes.
If standard_serving_type is missing, fall back to your existing serving-size selection behavior.
If no suitable serving size is available, you should always allow users to manually enter weight or volume.
For the most accurate input possible, we recommend always offering a manual weight or volume input in addition to serving sizes, for users who are willing to put in a little extra effort to get more accurate evaluations.
