It's a little dishonest of this article not to point out that junk food is engineered- I mean literally engineered, by teams of scientists running controlled experiments- to be as addictive as possible. This isn't a question of those wacky consumers and their revealed preference not matching their stated intentions; human willpower should barely enter the conversation when this topic comes up.
If PepsiCo is genuinely serious about encouraging healthy foods, the only way that's ever going to work is if the Lay's and Doritos are re-designed to be less appealing. Putting them in a fight head-to-head with the healthy foods in their current state is a fight the healthy foods are always going to lose, even if Pepsi's intentions were pure as the driven snow. But they can't (again, irrespective of whether they're good or evil) because that would kill the brands and competitors would simply swoop in and take the market share; so once again we have a coordination problem where regulation is realistically the only solution.
