How would you define the level of "processed food"? Some processing is good and necessary. Some processing not so good. The quantification is even more difficult. In general, I wouldn't rely on any of such scores. My approach is: 1) I look at the ingredient list, which already tells a lot. 2) I assess the food quality with my own senses, if possible. Although sometimes color can be misleading. 3) The more bullshit bingo is printed on the packaging, the less likely I buy it. It takes a bit of experience but over time you get the drill.
