Mark Di Ionno writes in the San Francisco Chronicle how junk food companies have motivated Americans to literally eat ourselves to death: "Spend $12 billion a year on advertising. Put product on every corner. Don't stop until you've changed the American lifestyle." These are the "two main ingredients for the pervasiveness of junk food in our culture: advertising and availability." He lambastes children's TV ads for pushing hard for kids to see junk food as "cool." And he illustrates the "availability" issue thus: "Drive down any stretch of any highway and count the number of gas stations that sell soda and snacks. Then count how many can actually fix a flat tire."
