Why do we generally crave food that is bad for us, rather than healthy food?

I mean, sometimes I'm like aww yeah salad, but most of the time I'm just like aww yeah cheeseburgers. What's up with that?

Sugar and salt are things that we require to live and they used to be hard to get. Our ancestors were programed to eat as much of these things as they could, as these resources were scarce, people hardly ever over ate.

Now thanks to farming and industral scale extraction methods, we can get salt and sugar very easily. The problem is that our bodies are still wired to crave these things like there's no tomorrow.
