News story brainstorming

It is no secret to anybody that the United States seriously suffers from obesity. I wonder if the majority of Americans wish to live a healthier lifestyle, or if they only care for the happiness of their taste buds. I think it would be interesting to do a news story/survey on which people would choose: their taste buds, or the health of their bodies. I could use twitter to post if people would rather choose McDonald's or Saladworks. Not that Saladworks is much healthier, but it just the idea that they want to eliminate McDonald's out of their diet and get the vegetables in. I could ask for "retweets" for McDonald's, and "favorites" for Saladworks. By doing this, I think I could get an idea of what people wish to do in regards to their food choices. However, this could not be a fair test due to the fact that I would only get results from people my age. Still, it would be a good representation.
