The processing does matter, and the more processed it is the more fat, sugar, and salt companies can put in.

Or in some cases when they remove one component they have to up the others. See low-fat "yogurts", which end up adding lot of sugar to compensate for the fat content...

Or, viewed another way, the more processed it is, the more everything else is processed out, so that fat, salt, and sugar are almost all that's left.

What about protein bars? Those are processed foods where they add artificial sugars, protein whey, and artificial coloring.

It also tends to indicate that the main ingredients aren’t very nice unprocessed; otherwise they wouldn’t need so much processing.
