OK, I usually don't do this but I just can't resist.  Today, a search term that was referred to this site from Google was this:

    why do chinese people eat chinese food (source: www.google.co.uk)

The page they navigated to was my entry concerning a conversation I heard while in college living in Boulder, CO.  The entry was comical and was not to be taken seriously.  Since then, I get all kinds of searches for people wanting to know "what Chinese people eat for breakfast" but this is the first time anybody has asked the question "why".

Let me see if I can take a stab at a true honest answer:

Chinese people eat Chinese food because...

China is a country.  This country has many people.  These people are citizens of China, hence they are Chinese citizens.  The citizens of China do, in fact, eat food.  Now this is the tricky part, since they are Chinese and they eat food, one could deduce that Chinese people eat Chinese food.

Did I hit the nail on the head here or am I way off base?

Also, feel free to plug any country into the above explanation to see why citizens of other countries eat indigenous foods.  Example, did you know that French people eat French food?  Or that Mexican people eat Mexican food?  I bet you didn’t.  But now you do!
