PotatoFree - I do see your point: people do need to make educated choices. And I certainly believe that personal responsibility is key.

But, I do think that government sponsored support of corn/wheat products impacts people's choices. One of the reasons people, especially low-income people, buy junk food/fast food/corn/wheat products is that subsidies make it MUCH less expensive than other foods. Food companies would not use so much HFCS if it wasn't so inexpensive due to price subsidies.

There was an article (I believe that it was in the new issue of US News -- in a series of articles about obesity) that talked about how low income and inner city populations do not have access to fresh fruits and vegetables and they can get more "bang for their buck" calorie wise buying cheap fast foods. Even if they know what they should be eating, if it is not available or affordable, people will choose what is available and affordable.
