Chinese noodles

According to Wikipedia (I know, I know), the words "mein" and "fun" that appear in the names of Chinese noodle dishes are indicators of the type of starch the noodle is made from.  "Mein" noodles are made from wheat, and "fun" noodles are made from rice.  Not that lo mein can't be fun, mind you. [/obvious joke]

And, of course, in America foreign food terminology has a tendency to get really really confused, so there are no guarantees-- if you're trying to be gluten-free, buying chow fun might help, but then it might not.
