This means that items can be either be completed when there is data missing (and thus the food item can show a Health Rating as soon as complete) or you can correct incorrect entries.
You will be able to change/add:
- serving size
- all macros
You will be able to do so by clicking on the product in question and then on Edit Food. Then change/add the information in question and save your changes.
There are certain rules behind the editing so it is not possible to enter any value:
protein + carbs + fat = total amount of calories +/- 20%
Please note: Verified items have to be reported. In those cases Lifesum will change the data.
