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.

So much of what we see and hear about the Middle East focuses on what we call politics, which is essentially ideology. But when it comes to the Middle East, and especially the Arab world, simply depicting people as human beings is the most political thing you can do.

For my generation - the "Children of Nixon," as I call us in the book - the Lebanese civil war was an iconic event. Downtown Beirut became a metaphor for so many things: man's inhumanity to man, what Charles Bukowski called "the impossibility of being human." It shaped our perceptions of war and human nature, just as Vietnam did for our parents. We used it to understand how the world works.

I chose to write about food: food is inherently political, but it's also an essential part of people's real lives. It's where the public and private spheres connect. I wanted to show readers that the larger politics of war and economics and U.S. foreign policy are inextricably bound to the supposedly trivial details of our everyday lives.

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.

There is a feminist proverb I learned from my mother: The personal is political. There's a powerful literary stereotype that men write about war and politics and public life, while women confine themselves to family and food and personal life.

Being an American journalist can put people on the defensive. In countries where people assume the press is partisan, like in Lebanon, or where it had essentially become an extension of the government, like in Iraq, people tend to see a journalist as an agent of his or her government. That can be dangerous if the United States military is occupying their country, or aligned with their enemies.
