These indices were chosen because the DGE Ernährungskreis is an instrument that is familiar to the German population to some extent and can be depicted graphically. The FSA-NPS DI was chosen because the study by Wu et al. [2] showed that it is a suitable indicator for drawing conclusions about food intake using shopping data. After evaluating the receipts, it makes sense to display the results graphically on the smartphone (in an app) in a user-friendly way and thus show the users their previous individual shopping behavior. ...
