Your comment celebrates our grain based ag-industrial complex a bit too much. I know that a lot of health problems were eased by throwing vitamin and mineral supplements into packaged foods but today, it is this over-processed food that is making us sick and the solution isn't just routing another pipe into the vat at the frozen lasagne factory.
Also, "go the way of vitamin D" isn't a good outcome. There is a lot of room between "oh my god my kid has rickets" and getting "enough" vitamin D. We who dwell indoors in the north need way more vitamin D supplements than what we might get in enriched foods. And if we avoid those processed foods, I guess we need even more D (even if it comes from the same ag-industrial complex, I suppose).
