If you look at the purported dangers of salt or fat there is no consensus of support in scientific literature. So I would ask first: 'Is it possible to have an informed government that actually follows the science?' From what I've seen it's not likely.

A great deal has been written in recent years about the purported lack of motivation in the children of the Negro ghettos. Little in my experience supports this yet the phrase has been repeated endlessly and the blame in almost all cases is placed somewhere outside the classroom.
