Grade A large eggs were up nearly 35 percent during the same period and sliced bacon was up 4.6 percent.
There are a number of factors causing this run-up in food prices.
First, there is more money in a lot of developing countries. The upshot is that people can afford to eat more and also to eat foods they traditionally have not consumed, such as meat. So these countries then need more corn to feed their cattle, which drives up demand for the grain.
Also, the world's population is growing faster than the growth in food production.
Poor weather in some parts of the United States have also contributed to the run-up. Think floods and early frosts.
