I'm sorry, I think this article is idiotic. The relivence of this article is moot. We already know that the lower class is unable to purchase better, more nutrional food. We have to purchase what we can to survive, not what might have the most nutritional value. Exactly how much money did they spend to discover this? Could that money not have been used somewhere else? Like the Chattanooga Area Food Bank? Helping others even finding food to eat?
