Hedge against food prices? Buy lots of pasta and grains now. Dry goods, if stored properly, can keep for a good while. Pasta, rice, beans, and Textured Vegetable Protein. You can even venture into freeze-dried vegetables and fruit if you like.

That's not a hedge, that's just preparing a backup plan.

What I'm saying is can you buy REAL futures in foodstuffs such that if the price of food goes up, your options increase in value as well and the net effect is to remove the price risk?
