  2. The units field contains references to respective Food Units.

  • PUBLIC - Foods that are in Fitbit's public food database and are visible to any Fitbit users. Only Fitbit populates this database to avoid spam and duplicate entries.
  • PRIVATE - Foods created by a user either on the website or via the Create Food endpoint.
