When was the sugar-free soft drink which was a later entrant to the diet cola market unveiled
Diet Pepsi Diet Pepsi and Diet Pepsi Classic Formula Blend (stylized as diet PEPSI CLASSIC SWEETENER BLEND) are no-calorie carbonated cola soft drinks produced by PepsiCo, introduced in 1964 as a variant of Pepsi-Cola with no sugar. First test marketed in 1963 under the name Patio Diet Cola, it was re-branded as "Diet Pepsi" the following year, becoming the first diet cola to be distributed on a national scale in the United States. In the 1960s and 1970s its competition consisted of Tab, produced by The Coca-Cola Company, and Diet Rite soda, produced by Royal Crown. Diet Coke was a later entrant to the diet cola market; though shortly after entering production in 1982 it became the primary competing diet cola to Diet Pepsi.
Aspartame controversy The artificial sweetener aspartame has been the subject of several controversies since its initial approval by the U.S. Food and Drug Administration (FDA) in 1974. The FDA approval of aspartame was highly contested, with critics alleging that the quality of the initial research supporting its safety was inadequate and flawed and that conflicts of interest marred the 1981 approval of aspartame. In 1987, the U.S. Government Accountability Office concluded that the food additive approval process had been followed properly for aspartame. The irregularities fueled a conspiracy theory, which the "Nancy Markle" email hoax circulated, along with claims, counter to the weight of medical evidence, that numerous health conditions (such as multiple sclerosis, systemic lupus, methanol toxicity, blindness, spasms, shooting pains, seizures, headaches, depression, anxiety, memory loss, birth defects, and death) are caused by the consumption of aspartame in normal doses.
