Food Percentage

Thank you for adding a sliding bar to refine further the food footprint! However, I find it very cumbersome to use. Food types of low percentage end up higher on the graph (I'm assuming this bar goes low to high from left to right). As I move x food type higher, another seemingly random food type y goes lower (without moving anywhere on the graph). I understand why this happens in mathematical theory, but it becomes very confusing and tedious when one food type I had previously set now changes. It might be easier if there were simply a field for each food type and the user could enter his or her percentage. It's less clever and pretty, to be sure, but probably a lot less confusing.
