Paul Jaminet Nails It

I had to share this quote, because I think he's managed to sum up where the whole food reward thing contributes to the discussion while simultaneously shoving it gracefully into the corner it belongs in:

The difference with junk food is not that it is more palatable at the time it is eaten, but that it does not satiate or nourish and therefore the brain forces the person to go seek more food. What they are seeking is nourishment, not palatability. But they have learned to seek nourishment from unnourishing foods. That is the problem. 

 This is from one of his comments on his most recent post, here.  Just stellar.
