And why? A lot a Americans eat everything from tin, frozen, fastfood. No gourmet-culture.
Yeah you have to understand the American culture. Our country has a society that is prone to excesses of many kinds. This society is not homogenous at all, there tons of people who are enlightened and have a sense of how to live a healthy live, but equally there are tons of morons roaming the streets, who don't care about anything except living in the moment and give in to every impulse they have.
George Carlin had a great bit about American culture.
