These are the myLevels food scores, which measure the impact food has on your sugar levels.
The score is the difference between your sugar baseline and the elevated level after you have eaten.
For example, if your sugar level is stable at 5.5 and the food takes you up to 7.5, then your myLevels food score would be 2.0.
We do some smart stuff to help iron out scores when you've eaten two things at once, but we won't get into that here.
If your score looks really 'off' then you can click the dots and "report score" as too high or too low.
