A growing number of Americans are adding "food prices" to their list of worries.

USA Today reports that 73-percent of Americans say they're concerned about the higher cost of food - and with good reason, too. 

Corn, wheat, soybeans and other grain prices have surged to record prices this year.

Also, over the last 12 months, milk is up 13 percent, white bread is up 16 percent and eggs are up 35 percent. 

"I'll drive farther, even though gas is higher, if there's a bigger price savings at another store," USA Today quoted one Indiana shopper. "It's hard on us, but it's harder for families with kids," she said.

Analysts are blaming the rising prices on growing demand for food in countries like China and India

The paper also reports that about one-third of the U.S. corn crop will go to producing the new bio fuel, ethanol.
