I attended the Wisdom 2.0 conference last year where the unconference was hosted at Google. I heard tell of these vending machines where price reflected the true cost to your health.
I am hesitant to deify Google, but this was yet another brilliant innovation on their part that should be replicated across America. #justsayin
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
