This is, in fact, the only example I have heard of of different food preferences across ethnic groups. But in this case there is only one change to be made—removing milk from the diet—and regardless, some europeans are lactose intolerant too.

I’m not sure it exactly counts as food, but there are substantial geographical variations in genes related to alcohol metabolism.
