Cornell University researched the impact of eliminating chocolate milk from elementary schools. Some thought it would be a no-brainer; that kids would have a more nutritious lunch. Wrong.

At 11 Oregon elementary schools where students were denied the choice of chocolate milk, students drank 10% less milk. There was also a 29% jump in the amount of white milk wasted, left on the tray and discarded. Nutritionally it meant fewer calories and less sugar, sure, but it also meant less protein and less calcium. Hardly a success. Inexplicably, it even coincided with a 7% drop in the number of students even participating in the school lunch program. Fail. No word on if those 11 schools will reintroduce chocolate milk.
