Vitamins A and C are out, D and potassium are in
Everyone's inside on computers all the time and it's making them lonely and sad and deficient in vitamin D and potassium. Americans used to be deficient in A and C, but a new era calls for new vitamin deficiencies -- which means vitamin D and potassium levels are required, while A and C move into the "optional" category.
All in all, these aren't bad changes
Look, say what you will about the effectiveness and speed with which vast government bureaucracies operate, these changes at least acknowledge two fundamental problems with the American food industry: huge serving sizes and too much sugar, the latter of which contributes to all sorts of nasty health problems from diabetes to heart disease and so on. So now all the FDA has to do is convince people to read these things, which shouldn't be too hard at all, since Americans are known for adapting well and without uproar to information that might require them to modify their behavior.
