When were nutrition labels introduced in the us?
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".
