My mom recently sent me an email about what the world eats in pictures. I tracked it down to a Time Photo Gallery: What the World Eats which was inspired by the book Hungry Planet: What the World Eats.
The pictures are at least as interesting as the other cultural comments as they are for the food commentary. Don't miss the cost of the food and what their favorite foods are. There is a lot packed into such a small package that you could probably take the better part of an hour just gaining a basic understanding of what there is to see.
I saw this on the BBC News website. I found it as fascinating as you did. You wonder how some people make it.
