I'm still trying to get past Sid saying that Europeans don't eat corn! What?! This is the first I've heard of it. How can you not like corn?
I think it is most of all a climate thingy.
There are other crops that do better, make more profit to grow over here.
How good corn ripens in Western Europe is to unpredictable for commercial food production. But the large plants make excellent animal food for the winter whether or not the plant ripens completely. So a lot of farmers with cows grow corn, but not for the corn cobs. They grow varieties that grow high and make large leaves. Cobs? Not important to them.
We eat popcorn and cornflakes. You can even find corn based bread if you really look for it. But all that corn has to be imported. That's why a corn bread is generally more expensive here than a bread made of wheat. Hence only for the real fans of it.
If I have the choice between a more luxury whole grain bread or a corn bread (price wise almost the same), the corn bread looses.
There is an increase of corn production in some countries in Eastern Europe though. They have longer, warmer and sunnier summers.
