I mainly feel negatively towards the food industry for this. I mean, if you put a bunch of humans in a place where Cheetos and KFC grew on trees, we'd be having the same problem.

This type of food simply shouldn't be consumed as a main source of energy. And the fact is, many humans will inevitably gravitate towards the cheapest and most convenient food source. No amount of cultural enlightenment is going to eradicate this. It'd be wonderful if it could, and if these campaigns for healthier living would convince every person to stop eating badly on their own conscious terms. But right now they're competing with a massive, expensive food industry that makes all of its money from doing the exact opposite.

IMO the solution will be in the direction of strengthening awareness of why this food is bad for you, awareness of exactly what the food industry is doing, AND getting everyone on the collective ass of the corporate food giants. Probably disallowing junk food to be bought on food stamps, too.

If a company claims to provide food, and all they provide is sneaky snacks that mess with your body's ability to understand what it's actually getting, nutritionally... it's just not right.
