I can translate all of that except "overlidom" and "penmetallia". The latter is what I'm used to seeing as "transition metals"? If so:
Too bad there's so little of it; it would be useful in so many ways.
Wikipedia says it "has the highest magnetic moment (10.6=B5B) of any naturally-occurring element and possesses other unusual magnetic properties."
That's the sort of thing that drives me crazy(er).
Could be their physical characteristics aren't amenable to typical manufacturing processes. Look how long it took ceramic magnets to get from the lab bench to car speakers.

Oh, I could have said "suitably combined" as in carbohydrates, fats, and proteins, but in the SF world the concept of "CHON food" is so old hat I didn't think it needed explaining.
Also I rather should have said that the other two elements you allowed be taken by fractions from the other less prominent but eventually equally necessary components of food; Ca, K, P, I, the assorted so-called trace metals, and so on.
And a rather important component of foods like garlic. Yummy!
The media. Feh! They're lucky to say "element" when that's what they mean.
