The Power of the Food Movement?

According to this article (HT Farmpolicy), consumption of high fructose corn syrup is down by 11 percent from 2003 to 2008.  The only thing in the article to explain the drop is consumer, and hence processor, resistance.  I know corn prices jumped over the same period, so it might be that "pure sugar", nature's food, processed from sugar cane or sugar beets, became a better buy over the time period.  But regardless of the explanation, the food movement will take credit and thus become more powerful in the eyes of other players in the food arena.
