The only place on the campus where employees pay for food is from a vending machine. The pricing strategy is based on nutrient content, again according to the Harvard pyramid plan.  For the vended products, you pay:  one cent per gram of sugar
  two cents per gram of fat
  four cents per gram of saturated fat
  one *dollar* per gram of trans fat


That's very cool.  I'd love to see this concept get wider usage.
