It can still be simple -- look at it like this: 200 calories of Oreos provides very little additional benefits, while 200 calories of meat provides more additional benefits for your diet. It doesn't matter as much when comparing Oreos to meat, but it really matters when you're comparing orange juice to soda. The processing might play a factor, but really you're looking for calories containing nutrients that keep you alive and healthy -- processing level is pretty subjective.
