Nutrition facts label
Additionally, there is a requirement for ingredients to be listed in order from highest to lowest quantity, according to their weight.
The label was mandated for most food products under the provisions of the 1990 Nutrition Labeling and Education Act (NLEA), per the recommendations of the U.S. Food and Drug Administration. It was one of several controversial actions taken during the tenure of FDA Commissioner Dr. David Kessler. The law required food companies to begin using the new food label on packaged foods beginning May 8, 1994. (Meat and poultry products were not covered by NLEA, though the U.S. Department of Agriculture proposed similar regulations for voluntary labeling of raw meat and poultry.) Foods labeled before that day could use the old label. This appeared on all products in 1995. The old label was titled "Nutrition Information Per Serving" or simply, "Nutrition Information".
Reference Daily Intake
On May 27, 2016, the FDA updated the regulations to change the RDI and Daily Values to reflect current scientific information. Until this time, the Daily Values were still largely based on the 1968 RDAs. The new regulations make several other changes to the nutrition facts label to facilitate consumer understanding of the calorie and nutrient contents of their foods, emphasizing nutrients of current concern, such as vitamin D and potassium. The revision to the regulations came into effect on 26 July 2016 and initially stipulated that larger manufacturers must comply within two years while smaller manufacturers had an additional year. On September 29, 2017 the FDA released a proposed rule that extended the deadline to January 1, 2020 for large companies and January 1, 2021 for small companies.
