 These will be used to calculate the total nutrients of a recipe.
 Because adding all the properties to a food by hand is quite annoying I built this importer to import data provided by the [USDA Food Database](https://fdc.nal.usda.gov/fdc-app.html#/food-search?query=&type=Foundation) using the [API](https://fdc.nal.usda.gov/api-spec/fdc_api.html).

 ## How does it work?
 1. The program reads the [appsettings.json](./appsettings.template.json) to find the Tandoor instance and to get the needed API-Keys for Tandoor and the USDA FDC database.
 2. After that all properties and all foods are retrieved from the Tandoor instance.
 3. For each food item retrieved from Tandoor the FDC ID of that food item (retrieved from the URL of the `Food`) is used to query the FDC database for nutrients.
 4. All nutrients of a food item are retrieved, then the nutrients that are not present in Tandoor are filtered out.
