Today, the US Food and Drug Administration finalized its design overhaul of the nutrition facts label, a major change to health information provided on Americans' food packaging.

The calorie count on the new label is significantly larger, as is the serving size. Vitamin D and potassium will now be added to the label, while Vitamins A and C will be dropped. "In the early 1990’s, American diets lacked Vitamins A and C, but now Vitamins A and C deficiencies in the general population are rare," the FDA says. "Manufacturers are still able to list these vitamins voluntarily."

The classic footnote description of Percent Daily Values is also getting a minor change for clarity. "The % Daily Value (DV) tells you how much a nutrient in a serving of food contributes to a daily diet," the new note reads. "2,000 calories a day is used for general nutrition advice."

Food manufacturers have until July 2018 to comply with the new regulations. Smaller manufacturers with less than $10 million in annual food sales have until 2019.
