Body needs protein, you crave an Angus steak (based on previous tasting of a steak, and how the body reads it). Uncivilized animals seem to operate this way, why wouldn't we before the advent of modern foods and advertising.

I also tend to believe that we had (like animals) an intuitive sense of what would poison us (before refined sugar). Certain compounds would send an immediate signal that this was not edible. Now that we are eating "parmesan cheese" made out of wood fiber, we've completely lost the ability to pick up on those subtle signals. And of course if you are starving, you'll eat just about anything in desperation. So if our bodies are "starving" for nutrition, and we're just filling our stomach with crap, not getting the vital nutrients we need, then we'll just keep eating to try and fill that void--even if it should signal as "poison".
