Feels like they are jumping the gun in terms of saying this could help with malnutrition in developing countries. Starving and malnutrished people can't just drink a meal replacement shake and be fine, especially kids. There are many other factors that must be taken into consideration. For example see http://en.wikipedia.org/wiki/Plumpy%27nut . I saw this on 60 minutes a few years back.

"Plumpy'nut is a peanut-based paste in a plastic wrapper for treatment of severe acute malnutrition... They are also relatively high in calories, which means that a patient receives a lot of nutrition from small amounts, important because malnutrition shrinks the stomach."
