Easily digested whole food maize porridge

Hi! Based in southern ontario and I'm trying to eat more maize (i.e. corn) in the diet. I have had success with eating poridge made from hominy flour but it is quite pricey. Given that maize is so cheap, does anyone know where else to source maize from (other than the small bags of it at international food stores)? Like, is maize fed to animals excessively different from the maize for humans?
