Grain and the ghetto
Here's another interesting article on making convenience store food healthier. Having lived a half block from one for two years, I can testify that these places are a major food source in the inner city. For people without reliable transportation (or inconsistent adult supervision), it's a whole lot easier to just get a back of chips or a hot dog at the local gas station. When I think about my (possible) future work as a geographer, one interest I have is in learning more about the public health research that's gone on with this issue. As this article states, it's hard to tell someone to eat healthy when the options just aren't there, due to price or geography.
