Fat China: The Impact of China's Growing Waistlines

All kinds of adjectives have been used to describe China's growth. The obvious signs of it have been shining new skyscrapers, bullet trains, shopping malls and luxury goods enjoyed by a burgeoning consumer class. But there's another sign now of a quite different kind of growth in China. Unprecedented, exponential....and really quite worrying. Because another thing that is burgeoning is people's waistlines. Hundreds of millions of Chinese have gone from a simple farmer's diet of fresh fruit and vegetables to an urban one filled with fast food - all in the span of a decade or two. The BBC Business Matters' Mark Whittaker speaks to Paul French, author of a book called " Fat China: How Expanding Waistlines are Changing a Nation." Mark is also joined by Simon Long, Asia Editor at The Economist.
