Get ready for higher food prices

``Warnings of higher food prices headed for American supermarkets and restaurants were swallowed easily across much of farm country Wednesday... The price of corn, which has doubled over the past six months, affects most food products in supermarkets. It's used to feed the cattle, hogs and chickens that fill the meat aisles... Shoppers could see higher grocery bills as early as three months from now, though most of the impact won't be felt for another six months, said Scott Irwin, an agricultural economics professor at the University of Illinois.''
