Global Grub

The husband/wife team of Faith D'Aluisio and Peter Menzel, authors of Sierra Club books, Material World and Women in the Material World, have come out with a new volume called Hungry Planet: What the World Eats, which explores the global diet by looking at what families around the world eat in an average week. Time magazine has a photo essay from the book on its website, and NPR talks with the authors.
