ELI5: Why does any food that's really healthy taste like cardboard and anything evil like gravy or bacon taste like heaven?

Isn't your body supposed to tell you "this is bad, so here's a bad taste in your mouth" or "here's some delicious healthy steamed bruxel sprouts, here's a taste bud explosion!"??

Because stuff like bacon and gravy have extremely high caloric value in comparison to fruits and veggies. Back in our hunter/forager days, getting enough calories to not starve to death was far more important than having a balanced diet to promote optimum health, so we evolved to go nuts for those things whenever we got the chance.
