Both scenarios seem plausible to me.

And "enjoying" them, in the case of dairy, might include more than taste or
satiating hunger.  I ate some dairy recently, which led to eating it another
couple of times.  I had a pleasant mood-food response.  Subtle, yes, but
noticeable for a nice smooth feeling.  Maybe the casomorphin?  Back when I
ate dairy pretty often, I never noticed any effect from it.
