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
The Recommended Dietary Allowances (RDAs) were a set of nutrition recommendations that evolved into both the Dietary Reference Intake (DRI) system of nutrition recommendations (which still defines RDA values) and the RDIs used for food labelling. The first regulations governing U.S. nutrition labels specified a "% U.S. RDA" declaration based on the current RDA values, which had been published in 1968. Later, the % U.S. RDA was renamed the %DV and the RDA values that the %DVs were based on became the RDIs.
