I think the point of obsession with food means we're healthy as a species. When we're hungry, everything tastes good, hunger is the best spice. When you're in a area that has few resources, you work incredibly hard to have something. And then you make the something taste good. The greatest food in the world comes from the inventiveness of great privation. What emerges is all the miraculous fermentations and all the strong flavors. You put it together in the right way, it's delicious. That defines survival, and our human species.
