Well here in Germany we have the Problem of the rising footprices too. i dont know anything about the foodprice situation in the US so i cant answer your questions *sry*^^
i think that the high fuel prices are here a little problem too but that is not the importent one. the problem here is that the farmes are selling the corn to the fuelconcerns, which are giving a good price for it, to make biofuel. Or they are makeing electricity out of the corn (biomass power stadions).
i think its shit to fill our cars with regenerative fuel when the people in africa have to die cus they have no food.....
i could imagine that the situation in the US is like here because Europe and the US arent soooo different^^
(sry for my bad english)
