In the app, I use the “Lowest First” principle in the statistics.
This means that the “worst” meal is counted rather than each individual meal.

Example:
If you eat 2x vegan and 1x with meat on one day, this day is counted as “omnivore” and flows that way into the statistics.
If you eat vegan 3 times in one day, this day will also be marked as “Vegan”.
The individual results of each day then proceed into the statistics.
