The problem here is that these chemists always seem to believe they have covered all the bases - until a bunch of people get sick because there's too much of this, or not enough of that, or something's missing all together. A couple decades ago there was a "baby formula" like that (can't recall which) that was found to be missing a number of elements crucial to early development. Lots of pissed off parents.
If they really want to create a super food, the ingredients should be: animal protein and fat, vegetable, fruit.
Oh crap, that's already been done. Hmmmm.
