Soon, all the food at the grocery store will have a single-number ranking, somewhere between 1 and 100. It's called the Overall Nutritional Quality Index ("ONQI") and it's been developed by a group of nutritional experts, with a Yale PhD at the helm.
I haven't seen the actual rankings yet, but I'm assuming that organic cabbage gets something like a 97 and cotton candy gets a 2. Something like that.
