There seem to be three groups: The normalised serving/100g group does not seem to fit the 100 ml group. I need to recheck this one. The per gram peak at 857 kcal seems too much off. This data seems to come from the USDA import. In some cases the normalisation was already in the import (blue part). The green ones were done by me. So the normalisation (14g/15ml) I used is not sufficient, I am missing another component.

The three peaks seem to indicate that there are three groups. The peak seen around 857 kcal seems a off. We would expect it to be around 900 kcal. Products in this peak belong to 100g group and the per serving group. It looks like the normalisation (which was based on the fats), did not work out well. So what happened?

Th 100g-group products seem to come from the USDA import, but the data was per 100g and not per serving as you would expect for this import. So the normalisation was already done, but wrong.
