Because rats sometimes got cancer after drinking the equivalent of 20 cases a day?
Because of course obesity carries no health risks...
Hey! I have an idea! Since ALL food can be abused, and obesity itself has health risks we could:
A) ration all food, after making sure that the food that WAS allowed was healthy by the standard du jour
or
B) only allow the health food du jour, and enforce exercise through labor camps!
That will keep those insurance costs down!
