I couldn't understand why they were concentrating so much on the "processing" part of it - it's the garbage they add (and the nutrients they remove) in creating UPFs so that it lasts on the shelf for months or years that's the real problem.

Combine that with the sugar/salt/seed oil ratio that makes it incredibly addictive, and you have practically entire populations filling up on this nutritionally bankrupt junk.

The traffic light isn't going to tell them much about what's actually IN the food they're buying - you can have a highly nutritious roasted chicken labeled with all red lights simply because of the nutrients inherent in roasted chicken, and a nutritionally bankrupt candy bar made sufficiently low enough in all the "bad" things to meet the standard for green lights.
