Diet Pepsi is a diet carbonated cola soft drink produced by PepsiCo and introduced in 1964. In 1984, PepsiCo announced that it would stop using saccharin in its diet soft drinks and switch to NutraSweet, an artificial sweetener. This change was made to improve the taste of the company's soft drinks and to gain a competitive edge against products containing saccharin, which has an unpleasant aftertaste for many consumers. NutraSweet, approved by the Food and Drug Administration for use in soft drinks in 1983, has faced controversies over its possible health risks, although no concrete evidence has been found. The debate around artificial sweeteners continues, with recent studies suggesting potential health concerns associated with their consumption.

What You'll Learn

Nutrasweet was approved by the FDA in 1983
NutraSweet, an artificial sweetener, was approved by the Food and Drug Administration (FDA) for use in soft drinks in 1983. The approval came after several controversies and safety concerns regarding the use of aspartame, the primary ingredient in NutraSweet. Aspartame had initially been approved for use in dry foods in 1974, but its approval for use in soft drinks was highly contested.
The controversy surrounding aspartame centred on potential health risks, particularly its alleged involvement in causing brain tumours. However, the FDA maintained that aspartame was safe, citing it as one of the most thoroughly tested and studied food additives they had ever approved. The FDA's approval of NutraSweet in 1983 was a significant milestone, as it allowed for its use as a sweetener in carbonated beverages, specifically diet soft drinks.
In the case of Diet Pepsi, the decision to switch to NutraSweet was made to enhance the taste of their diet soft drinks and gain a competitive edge over products containing saccharin, another artificial sweetener with an unpleasant aftertaste for many consumers. This switch occurred in 1984, a year after NutraSweet's approval by the FDA, and marked a significant change in the formulation of Diet Pepsi.
The use of NutraSweet in Diet Pepsi was part of a broader trend in the soft drink industry, as companies sought to meet the changing dietary preferences of consumers and tap into the growing market for diet soft drinks. The approval of NutraSweet provided these companies with a new option for sweetening their products, moving away from saccharin towards a sweeter and potentially more appealing alternative.
While NutraSweet's approval by the FDA in 1983 was a pivotal moment, it continued to face challenges and controversies. Critics questioned the approval process, alleging irregularities and conflicts of interest. However, regulatory and scientific authorities in various countries have consistently evaluated and approved the use of aspartame, considering it safe for consumption when used under approved conditions.

Pepsi switched from saccharin to Nutrasweet in 1984
PepsiCo Inc., the soft-drink unit of Pepsi-Cola USA, announced on November 1, 1984, that it would stop using saccharin in its diet soft drinks and switch to Nutrasweet, an artificial sweetener also known as aspartame. The reformulated products, Diet Pepsi, Diet Pepsi Free, and Pepsi Light, were to be available in some markets by the end of November 1984 and nationwide by January 1, 1985.
Roger A. Enrico, then president and chief executive officer of Pepsi, said that the change was made to improve the taste of the company's soft drinks and to gain an advantage over competing products that contained saccharin, which many consumers found to have an unpleasant aftertaste. In fact, in 1976, the FDA recommended banning saccharin because tests showed that it gave cancer to laboratory animals. Although Congress prevented a ban, products containing saccharin were required to carry warning labels.
Aspartame, on the other hand, was approved by the FDA for use in soft drinks in 1983, more than a decade after it was first tested. It was quickly adopted by the soft drink industry, which found that consumers preferred the taste of aspartame to that of saccharin. Pepsi's switch to Nutrasweet was expected to give the company a competitive advantage over its rivals, particularly Coca-Cola, which was still using a blend of Nutrasweet and saccharin in its diet cola products.
The switch to Nutrasweet was not without controversy, however. Aspartame was (and still is) significantly more expensive than saccharin, and there were concerns about possible health risks associated with its consumption. In fact, consumer groups questioned the validity of the FDA's testing and reported adverse reactions to aspartame, ranging from headaches to mood alterations. Nevertheless, PepsiCo pushed forward with the change, confident that it would provide a better-tasting product that would attract new consumers to the diet soda category.

Nutrasweet is commonly found in tabletop sweeteners
Aspartame is a popular sweetener that is 200 times sweeter than sugar. It is commonly found in tabletop sweeteners like NutraSweet, Equal, and Sugar Twin. In 1974, the FDA approved its use as a tabletop sweetener, and it can also be used in gum, cereals, instant coffee, dairy products, and other food and beverage items.
NutraSweet, a brand name for aspartame, has been a subject of controversy due to concerns about its possible health risks. In 2023, the World Health Organization's International Research Agency on Cancer announced that aspartame is a possible carcinogen. However, the FDA and another WHO group, the Expert Committee on Food Additives, stated that aspartame is safe for consumption when used under approved conditions. The daily intake limit for adults set by the FDA is 50 milligrams per kilogram of body weight.
Aspartame is widely used in the food and beverage industry, with analysts noting its contribution to the growth of the diet soft drink market. In 1984, PepsiCo switched from using saccharin to NutraSweet in its diet soft drinks, including Diet Pepsi, to improve taste and gain a competitive edge. This decision was influenced by consumer preferences and the goal of enhancing Pepsi's market position.
While saccharin has faced safety concerns in the past, it has since been deemed safe for human consumption by the National Toxicology Program of the National Institutes of Health, and the warning label requirement has been removed.

Nutrasweet is considered a 'possible carcinogen' by the WHO
Nutrasweet is the brand name for the sweetener aspartame. Aspartame has been the subject of health concerns since its approval by the Food and Drug Administration (FDA) in 1983. Aspartame is an artificial sweetener that is 200 times sweeter than sugar and is widely used in food and beverage products, including diet drinks, chewing gum, gelatin, ice cream, dairy products, breakfast cereal, toothpaste, and medications.
In 2023, the International Agency for Research on Cancer (IARC), a cancer research agency within the World Health Organization (WHO), classified aspartame as "possibly carcinogenic to humans" (Group 2B). This classification is based on limited evidence that aspartame might cause cancer, specifically liver cancer, in humans, as well as limited evidence of cancer in experimental animals and possible mechanisms for causing cancer. It is important to note that the Group 2B classification is generally used when there is limited but not convincing evidence for cancer in humans or convincing evidence for cancer in lab animals.
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) reaffirmed the acceptable daily intake of aspartame at 40 mg/kg of body weight. JECFA concluded that the available data did not provide a sufficient reason to change the previously established acceptable daily intake and that it is safe for consumption within this limit. JECFA's assessment considered how, how often, and how much people might be exposed to aspartame as a food additive.
The FDA has reviewed more than 100 studies on aspartame and continues to monitor new evidence. The FDA disagrees with IARC's conclusion, stating that there are significant shortcomings in the studies on which IARC relied. The FDA has determined that aspartame is safe for the general population under certain conditions of use and has established an acceptable daily intake (ADI) for aspartame, which is considered protective of public health. However, people with the rare genetic disorder phenylketonuria (PKU) should avoid or restrict aspartame consumption.

Pepsi's switch to Nutrasweet was a marketing tactic
Pepsi's switch to NutraSweet in 1984 was a marketing tactic to improve the taste of its soft drinks and gain an advantage over its competitors. The company announced that it would stop using saccharin in its diet soft drinks and replace it with NutraSweet (aspartame), an artificial sweetener that was considered to have a better taste and was approved by the Food and Drug Administration in 1983. This move was in response to the success of Diet Coke, which used a blend of NutraSweet and saccharin, and the growing consumer preference for diet soft drinks.
Roger A. Enrico, president and chief executive officer of Pepsi-Cola USA, stated that the change was made to enhance the taste of their products and differentiate themselves from competitors using saccharin, which had an unpleasant aftertaste for many consumers. This tactic proved successful, as Diet Pepsi sales increased by 30% with the adoption of the aspartame-saccharin blend, attracting millions of new consumers to the diet soda category.
Pepsi's switch to NutraSweet was a strategic move to capitalize on the growing popularity of diet soft drinks and challenge Coca-Cola's dominance in the market. By offering a product with improved taste and no metallic aftertaste, Pepsi positioned itself as a strong alternative to Diet Coke and other competitors. This move intensified the competition between the two soft drink giants and demonstrated Pepsi's willingness to adapt to changing consumer preferences and market trends.
The switch to NutraSweet also had financial implications for Pepsi. Aspartame was several times more expensive than saccharin or sugar, but Pepsi chose not to raise its prices despite the increased cost. This decision may have contributed to squeezing the company's margins, as predicted by analysts. However, the investment in a better-tasting product seemed to pay off, as Diet Pepsi gained popularity and market share.
In conclusion, Pepsi's switch to NutraSweet was a well-timed marketing tactic that allowed the company to enhance its product offering, differentiate itself from competitors, and capture a larger share of the rapidly growing diet soft drink market. By prioritizing taste improvement and responding to consumer preferences, Pepsi was able to successfully navigate the highly competitive soft drink industry and solidify its position as a leading brand.
