Diet Studio contains data source file with food related data. It is a compilation one of publicly available food nutrition databases. Since the version 1.0.7 Diet Studio uses USDA Food and Nutrient Database for Dietary Studies, 3.0 (FNDDS) database for food nutrition facts. Previous versions of the application used USDA National Nutrient Database for Standard Reference SR18, SR22 databases.
The data source had been changed because of following advantages of FNDDS 3.0:
Data source file(s) are located in data folder and have xml format. Root node of these files defines its source by attribue Name: <DataSource ID="2" Name="FNDDS3">. That name is the name of the root of Food Tree in Ingredient view.
Diet Studio loads data from file defined in config.xml in section General as Data Source parameter. It is not recommended to change data source and this setting can not be set in Settings Manager by default. You can change it manually if you need use data source from previous version.
Documents created with version prior to 1.0.7 can not be modified without loss of data.
