I don't know why the US doesn't consume more beans, but I understand the UK doesn't. They only know the canned bean that is horrible. A friend once asked me why would you cook beans. I can't explain, you have to try.
Canned beans must be cooked properly, without that they are bland. I usually buy cans of beans without any sauce, species or tomato, then use them as an ingredient in cooking with meat, vegetables and proper seasoning. Also they are great in salads.
