Integrated Food Security Phase Classification

The missing piece from the http://en.wikipedia.org/wiki/Integrated_Food_Security_Phase_Classification is that malnutritioun may be based on the quality, not quantity - of food. For example, 35% of Americans Are Obese due to unhealthy food. According to the Food Security Phase Classification, America may be said to be in a Humanitarian Emergency, but this term is not in general applied to the US population.
