Food prices are now at an all-time high, according to the U.N. Food and Agriculture Organization.
Wheat cost twice as much in January as it did last June, pushing an additional 44 million people worldwide into poverty.
Higher prices of staples, particularly wheat, helped drive the public anger in Egypt, the world's largest wheat importer, where the average family spends 38 percent of its income on food (compared with 7 percent in the U.S.).
"Some days we do not eat dinner," said Cairo truck driver Ahmed Said, who went on strike for higher wages after President Hosni Mubarak's government fell. "If our child goes to the hospital and we have to pay for that, then my wife and I do not have a meal.
How can Mubarak be worth so much and we have so little?"
