Is the United States a health conscious nation?

First, the United States is filled with fast food restaurants at every corner. Research has shown that almost all of our nation eats unhealthily. A big example are school lunches. They have gotten better recently but they have always only had unhealthy choices. But now they actually have some salad or fruit instead. The US citizens see these everyday choices as normal and automatic. Concluding, the only way we can change this normality is if we be the example and change ourselves.
