Aspartame is the technical name for the brand names, NutraSweet, Equal, Spoonful, and Equal-Measure. Aspartame was discovered by accident in 1965, when James Schlatter, a chemist of G.D. Searle Company was testing an anti-ulcer drug. Aspartame was approved for dry goods in 1981 and for carbonated beverages in 1983. It was originally approved for dry goods on July 26, 1974, but objections filed by neuroscience researcher Dr John W. Olney and Consumer attorney James Turner in August 1974 as well as investigations of G.D. Searle's research practices caused the US Food and Drug Administration (FDA) to put approval of aspartame on hold (December 5, 1974).
