If one cent equaled one calorie, I definitely think the world would have better eating habits. McDonald's and all other fast food restaurants would slowly go bankrupt because their food items are simply too expensive, No one wants to pay over $13 for a hamburger that's only going to make you feel sick. Money is more important than health in this world, which is what would end up showing if each calorie cost one cent. The more unhealthy the food, the more calories it has. The more calories it has, the more it's going to cost. The healthy food has a very low amount of calories, and so it would be cheaper and people would be buying that more. Of course you would still get the odd people that just want the Big Mac and don't care about the pricing, but in the long run I think most people would choose money over taste. It's sad that people would only stop eating junk food because it gets too expensive, rather than because it's not good for your body or health.
