This is a lie spread by the meat industry to imply that the majority of farmland used for animal feed couldn't feed humans. The 'useless' kind of corn is the kind that stores well and has high protein and caloric value and can be made into a variety of shelf stable foods. Animal feed corn isn't as tasty as other kinds of field corn (which can be grown on the same land), but other than that it's what you want as bulk primary food (where sweetcorn is borderline useless). You need to soak it in lye or potash if you intend to eat a lot of it, this is the 'complicated processing' that is scare mongered. High starch varieties may lead to protein deficiency, but will keep someone alive.
