Fitbit Nutrition Export Format
The Fitbit Nutrition data export contains information from participants' food logs, including:
- Food Log Daily Summary — A high-level summary of each participant's daily food log.
- Food Log Items — A detailed breakdown of food log data. Each entry contains information for a particular food item including quantity and nutrition content.
The data in the Fitbit export is obtained through the Fitbit API. The available data will vary based on what the participant logs through Fitbit. See the Fitbit "Get Food Log" documentation for more information about using and interpreting Fitbit data.
