But being an American woman married to an Arab guy - and a Muslim to boot! - put me in a different category. People would open up, and tell me things that they would never tell another journalist, no matter how persistent.

Americans are curious about the texture of everyday life in the Middle East because they rarely get to see it. I wanted readers to feel like they were sitting around the dinner table with me and my friends, hearing what average people really say and really think, [where] the dinner table is the best place to find out.

There were a hundred booksellers in the old round city founded by the eighth-century caliph al-Mansur. The café and wine-drinking culture of Baghdad has been famous for centuries; there was a whole school of Iraqi poets who wrote poems about the wine bars of medieval Baghdad - the khamriyaat, or wine songs, that I quote in the book.

But how can you understand a war without any knowledge of the society where it happens? It's like trying to understand birth without knowing anything about pregnancy or conception. Or like trying to understand our current economic collapse without knowing what a derivative is.

In the Middle East, bread is so essential to everyday life that word for it in Egyptian Arabic is aish, which means life. It's always been the staple grain. But the predicament is that the Fertile Crescent, where wheat cultivation began, has now become the part of the world most dependent on imported wheat.

The Middle East is the only region in the world outside of sub-Saharan Africa where rates of malnutrition actually rose over the past decade or two, instead of falling.

If you look at the list of the top wheat importers for 2010, almost half of them are Middle Eastern regimes: Egypt, Algeria, Iraq, Morocco, Yemen, Saudi Arabia, Libya, and Tunisia. Egypt is the number-one importer of wheat in the entire world. Tunisia leads the entire world in per capita wheat consumption. So it's no wonder that the revolutions began with Tunisians waving baguettes in the streets and Egyptians wearing helmets made of bread.
