I don't know which one you'd pay a premium for. You'd see which one you're selling more of and charge a premium for that. The reality is, foods aren't indistinguishable. They have different tastes, different marketing, different cultural value, etc. How "good" something is is not, and never was, a prime indicator of success in the marketplace or value to the consumer. If Pepsi wants to spend billions on advertising, people will buy Pepsi. I'd also venture a guess in saying that you don't just get a tally of every food component available within some distance of your house, their nutritional content and their price, and then you just optimize on nutrition regardless of what your favorite childhood dish was, or what you're in the mood for or what your friends are having. All I'm saying is it isn't that simple as turning into a simplified problem of supply and demand. Go to a fried foods place at a poor neighborhood and watch how people order; I sincerely doubt they'd always end up getting the cheapest thing just that's what they can afford. Certain lifestyle choices lead you to a certain lifestyle (or perpetuate it) and completely forgetting those choices for problems like obesity is being disingenuous with yourself.
