Mustard Greens vs. Taffy

The Overall Nutritional Quality Index is described as an:

…algorithm designed to generate a single, summative score for the “overall nutritional quality” of a food based on it’s micronutrient and macronutrient composition and several other of its nutritional properties

The idea is that all foods get assigned one simple number, from 1 to 100, that gives you an idea of how “good” they are for you. On this list of sample rankings, mustard greens, fresh strawberries, and raw spinach get a score of 100, while taffy and regular soda get a score of 1.

There’s a nice photo-spread in the September 2008 National Geographic (which you can read if you get your hair cut at Ray’s Place).
