In and of itself, iceberg lettuce is not "unhealthy". I agree with you on this. Still, no single plant can be relied upon as an exclusive diet staple. Even those at the top of the reccomended list.
However, it is not a myth that
no amount of supplementation can ever make nutritionally inadequate foodstuffs wholesome and complete. This is particularly true when discussing food plants.
Within plants there are hundreds, if not thousands of different phytochemical nutrients. Even at the level of science we have today, we can't even say how many or even how most of them work. Thus far only a tiny portion of these nutrients have been isolated and manufactured into supplements. One thing that nutrition science has figured out is that a great many of these phytochemical nutrients are only effective when present in tandem with certain others. Thus producing isolated supplement agents is pointless.
