Food is a part of culture, think of all the different foods the "old", immigrants introduced to "us".
Not just Chinese food either.
Somehow, the older wave seems like it must have been easier to accept, but I doubt if the established people looked at it that way.
Things took a turn with John Cabot, and Christopher Columbus, not to mention Leif Erickson.
Like it or not, I think we're stuck.
