This sounds like one of those situations that is being blown out of proportion. It seems reasonable that some organization, who actually understands the subject, would write a series of guidelines on how food should be handled. For example, if beef was being processed, what should the temperature be? How cold should the freezer be? How long can beef remain edible if it is stored a 3 degrees C, etc.
The controversy over the vitamins and minerals doesn’t seem to be about their availability, but more focused on the labeling and manufacturing standards. I can see the organic, natural food groups being unhappy if the labeling has to specifically state the truth, which is that most supplements have no valid, double blind testing to prove they work, so they would have to say on the label that they are not proven to do anything. This would be a bit of a problem for their sales effort.
But, it wouldn’t stop you from buying vitamin C if you wanted to.
