Exporting obesity to Mexico

Mexico is now the second fattest country in the world. The U.S., of course, is first. This is the result of increased presence of American fast food in Mexico, and a move away from a more traditional--and quite healthy--Mexican diet. U.S. investment can make your country fatter.

Some Mexicans say there's less space on an already crowded Mexico City subway because riders are getting larger. At a flea market in the south of the city, vendors hawk clothes brought from the United States made for overweight individuals.

Wow.
