There might be a lot you're missing. Nutrition is hideously complex, but since we're evolved to eat whole foods and there are a lot of bioactive enzymes and or compounds that aren't well known or in vitamin pills you could be missing out on something crucial.
And so any labeling system needs to emphasize that it is incomplete, and that vitamins/minerals that we've located might simply be the markers of good food: not the sole constituents. It's like correlations versus causality.
