Rising food prices are the result not of ethanol but a combination of other factors.  Among them is government regulations, energy, inflation and simple greed.  To test the concept of price rise do simply to corn run down an isle at the grocery store and check out the price of pop.  You will find that DIET pop is priced exactly the same as regular pop made with corn fructose.  Strange that a product without any food value has the same price as one that has some caloric content.  

Often left out in any discussion of food price is the energy savings that has been seen by the average person.   It's now conclusive that $1.09 a gallon is saved on every gallon of gasoline due to ethanol.  That savings should be considered when talking about food prices. 

The simple matter is things are going to cost more as the dollar is worth less. 

It's in the interest of special interest groups to blame corn for rising food prices or other social problems.
